Beta releases for mobile apps

My team is going through a beta release for our mobile app to get early feedback. We’ve noticed that our android app is struggling compared to iOS. It seems that having an extra hurdle with signing up for the android beta program impacts installations. Naturally we’d expect the android engagement to lag a little behind iOS based on the Aussie mobile usage market analysis but there is still a significant drop.

We have 428 iOS installs, and 99 android installs. That’s a 19% Android installation rate. We have roughly 75-80% successful registrations and return log ins once people actually figure out how to install the app.

Google Groups vs Test Flight

We are using google groups to manage the distribution of the android beta app and because it’s harder to use than test flight for iOS we’ve gotten less installations. It’s fascinating how an extra hurdle in the sign up process can impact installations.

Return Logins

Our android numbers appear to be higher than usual here but I think it’s to do with the timeframe I’m collecting these numbers over. We’ve had a few people install the android app before we officially started the beta release and I think they’ve been counted in this statistics.

Tools

We are using adobe analytics, test flight and using a closed test track via google groups to help us manage the beta app releases and to gauge engagement metrics. You can read more about our general mobile app test strategy here if you like.

What were your experiences going through a beta release process? What worked well? How did you improve the process?

The Y2K bug in the year 2038

Do you remember how the world freaked out over the potential Y2K bug when the year was changing from 1999 to 2000? A large mitigation factor was a huge outsourcing effort to India and it helped to establish India as the global IT giant it is today. So when not many bugs eventuated it was a bit anti climatic. 


Globally; $308 billion dollars was spent on compliance and testing and it helped build more robust systems that survived the system crashes from the 9/11 terrorist attacks. 


Well the y2k bug would only impact systems that used 2 digits to represent the year, i.e. using the DDMMYY format to save on memory.

And the world updated this and their systems every where. Businesses did a pretty good job of patching that bug before it became an issue. Bugs still did come up but the world didn’t end.

There’s another bug for 2038

However did you know there is another Y2K bug scheduled for the year 2038? Basically the way our current 32 bit computer systems count time is the number of seconds since 1970. In the year 2038 we get a bit overflow issue and that counter resets to zero. This is more likely to impact cheap embedded systems with limited memory or old legacy systems.

If we switch to a 64 bit counter, our sun will explode before we get the same issue. It’s like going from ipV4 (we are already running out of ip addresses) to ipV6 for the internet.

IPv6 – Let the Sky Fall!

2038 might feel like a long way away but here’s a story about pension payments breaking in 2018 due to this bug (20 years before this bug is meant to occur):

Is your system at Risk?

So, are any of your legacy systems at risk? Do you think you’d have them migrated to cloud infrastructure before this issue occurs?

How about setting up a test environment that’s configured to be 6 months ahead of production? Would that give enough time to find and fix these issues when they occur?

Mindmaps and Heuristics for testing

I like to use mind maps to help me test. Mind maps are a visual way of brainstorming different ideas. On a previous mobile team I printed and laminated this mind map to bring along to every planning session to help remind me to ask questions like, “What about accessibility? Automation? Security? or Performance?”:

As I go through exploratory testing (or pair testing), I’ll tick things off as I go and take session notes. Often this will involve having conversations with people, sometimes bugs are raised. 
Here is a quick mind map I’ll use for log in testing:

Heuristics for testing

This mind map approach can be combined with a heuristic test strategy approach or a nemonic test approach. Heuristics is a rule of thumb that helps you solve problems, they often have gaps because no mental model is perfect.

SFDPOT is a common nemonic that was developed by James Bach; who also developed Rapid Software Testing; a context driven methodology. James Developed his RST course with Michael Bolton

In SFDPOT each letter stands for something that is meant to help generate testing ideas, they are; Structure, Functions, Data, Platform, Operations and Time. Here’s someone’s blog on applying SFDPOT to a mobile app testing approach.
I tend to use all of these different approaches as part of my exploratory testing practices.

More resources

If you are interested in reading about exploratory testing Elisabeth Hendrickson has written this book called Explore It!, reduce risk and increase confidence with exploratory testing. Elisabeth also has this nightmare headlines game which is a fun tool for brainstorming potential error cases.

Your team could also go through the process of creating your own nemonic/mindmap to help you have consistency across different testing styles, maybe something that made sense for your context? 

You could also use mindmaps to feed into the different feedback loops you’d like to have in your team. You can read more in this mobile test strategy blog.

Conferences Mobile Testing Presenting Technology

DevWorld 2019

I recently attended /Dev/World in Melbourne this week. This is Australia’s only iOS developer conference. Here is my summary of the conference.

Photos from the conference on Twitter under the hashtag #DevWorld

Themes

There were a few themes that gleaned from the talks. These were;

  • Swift is the most talked about language in this space
  • People are still using Objective-C
  • Cross platform remains a hot topic (from iOS to mac, React Native and Flutter)
  • Augmented Reality is still a cool toy
  • How to build engaging experiences in your app
  • Game design stories
  • Testing

Sketchnotes

Here are my highlights:

You can access all of my sketchnotes on google photos here.

My Talks

I presented on swift UI & wearables using my sample poo tracking app as the basis for it. You can watch a similar talk from my twitch channel. You can also access my slide decks here. I also gave a lightning talk on how to do sketch noting. You can read this blog post if you are interested in learning about sketch noting. I also have this blog post on Right To Left bugs which was inspired from my talk if you are interested in reading more.

Recordings

Eventually the talks will be up on youtube under the AUC_ANZ youtube channel. You can access previous years talks there too.

Right To Left design considerations for mobile apps

We truly live in a global and inter connected society. But have you tested your app using a Right to Left (RTL) language such as Arabic? This blog post is a reflection on some of the design considerations to keep in mind when accomodating this.

Why does this matter?

Arabic is one of the top 5 spoken languages in the world with around 3 hundred million speakers and it is the third most spoken language in Australia. Even if you only release apps for the Australian market someone out there will have Arabic set as their default device language. It’s ok if you haven’t translated your app, but you should check that these people can still use it.

How do I test this?

Android

Enable developer options and select “Force RTL layout direction”. On My Samsung S10 this is what my screen and options look like after enabling this option:

iOS

In Xcode you can change the build target language to a Pseudo RTL language to see how your app renders in this way without having to change the language on your device.

Number pads

You don’t actually need to render your key pads in Right To Left, in fact it’s actually more jarring to render numbers in a RTL arrangement because ATM’s and phone pads are left to right in Arabic. Most Arab’s are use to globalised number pads. Samsung has an in-depth article on when RTL should be applied.

When I have RTL rendering set on my android phone, the log in pin screen and phone call functionality is in LTR. However some of my banking apps render their pin pads in RTL.

Common RTL Issues

I was pleasantry surprised to find out how many of my apps weren’t broken when I switched to RTL rendering. Facebook, twitter and email still look very good. Some apps (like my calculator) do not make sense to render RTL and they remain LTR:

Bug One: Overlapping labels

You will have to watch out for when labels overlap like in the domain app here:

Bug Two: Visuals doesn’t match written language

And when your text is rendered RTL but the visual cue is still LTR like in the shade bar for representing countries visitors to my blog in this wordpress statistics view:

Bug Three: Menu’s that animate from the side

In the app I’m helping build, the side menu renders pretty funkily in RTL mode, I can’t show you a screenshot of this behaviour but it’s probably the quirkiest RTL bug I’ve seen. If you find an app with bad side menu behavior in RTL please share your screenshots with me.

But here are some screenshots of the CommSec app on android (LTR on the left and RTL on the right for comparison)

Bug Four: Icon’s aren’t flipped

Often icon’s have a direction associated with them like the walking person when you get google maps directions. Sometimes it can look a little odd when they aren’t flipped correctly (as if they are walking backwards).

Have you seen these bugs before?

Please let me know your thoughts or experiences in supporting RTL languages. I’d love to hear your stories.

A Mobile App Test Strategy

Test strategy, what a funny concept. Now this strategy isn’t going to help you win any battles (this is where the word strategy comes from after all) but for lack of a better well understood term, this blog post is a reflection on what I imagine will work for my team*.

*disclaimer: what might work for my team might not work for yours. People are amazingly diverse and your team and company context is fundamentally different. Also this here is a wish list of what I think will work. It’s subject to change as we learn and evolve.

Context

First let’s set the scene. Our scrum team includes 1 Android developer, 1 iOS developer, 2 back end developers, 2 business analysts (1 is our scrum master), 2 testers and a team/tech lead. We are changing our team structure and I’ve come on board as a software engineer in test. Our team closely collaborates with the design team and they are included in our group email threads but don’t come to our retro’s. We have a 10 day sprint cycle that looks a little like this:

We have a daily standup, a few kick off meetings at the start of the sprint to lock in what we are working on for the next 2 weeks, some mid sprint review/next sprint refinement sessions and a few meetings at the end that help tie up what we’ve completed. Consider this a crash course in Scrum Agile if you will. Not everyone is required to attend all of these meetings and I won’t be covering these meetings in detail in this blog post.

Get to the Test Strategy

Yes I know, that was a rambling tangent but the context is important. Before I get into the good bits I’ll ask you a question;

Why do we even bother with testing?

Some people say, “to ensure the product works as expected” or, “to find bugs”, “it’s my job to test things” and these are all ok answers but they miss the point a little. Here’s my answer:

We test to get feedback on the state of the product. To help us answer the question, “are there any known risks with shipping this product to production?”

Paraphrased from conversations with Michael Bolton, the tester not the singer

Every part of the following strategy is all tied into facilitating feedback. The more timely and accurate the feedback the better.

Testing and quality is a team responsibility, it’s not just up to one person to be the quality gate keeper. My role is to help facilitate feedback

Layer One: The product design feedback loop

This is all a little out of scope of my teams day to day activities but this how our design team tests if we are building the right thing that users need.

User/Product Research

This might involve researching our market for current trends. How many of our customers care about their superannuation? What is their financial literacy? What type’s of problems are they facing? What are our competitors doing and how does their experience deliver value?

Wireframe/Design prototyping

Eventually someone will need to start sketching out some design ideas. What’s the user flow through a particular feature?

User Testing

This won’t happen for every new design, for example log in hasn’t gone through this process. Our new big features will go through this type of testing. This helps get feedback on the design and layout. Does it all make sense?

Design and user story creation

Out of all of the work, eventually the design team and the business analyst will work together to create acceptance criteria, refine the UI and get the rest of the team up to speed with the context of a feature. Our user stories and designs are usually shared on a confluence page and linked to Jira tasks. We use a GIVEN WHEN THEN structure for our user stories.

Layer Two: The code feedback loop

Exploratory Testing

All testing is exploratory in nature, its front and centre. It’s across everything we do. chaos engineering is a type of it as well as building the code locally. We use our skills, plans and judgement to determine when and how much testing is needed at any point.

Experience Testing

When we do the code review we will do exploratory testing based on the risk of the feature. Time boxed to a session or two depending on what has been built. We will look at the user stories, brain storm any more edge cases and consider if they are worth testing. Checking if the experience of the feature makes sense and if there are any ways people can get into some sticky unexpected situations.

Unit Tests

As a developer builds a feature, they will create unit tests based on the user acceptance criteria. Developers will use the tools they are most comfortable with the write these tests. If you’d like to read more Martin Fowler has this blog post on Unit Testing.

UI Automation

Here’s a visual risk for UI automation board; each feature is mapped against customer impact vs frequency of use

I have my visual risk board next to our team which we use to prioritise how much testing we build at this layer. We use Espresso for Android and XCUITest for the iOS app.

“Why not Appium?”, I hear you ask

Simple, when test code lives in a repository outside of your production code, you decrease collaboration with the whole team. Also you can’t easily run your appium tests during pre commit testing or locally as a developer. You can follow the interactive visual risk for UI automation exercise here to understand more.

Code Review

When a new API is being developed, I’ll often pair with the developer to do a code review. We will talk about the architecture, brain storm testing ideas, do a bit of testing (usually through postman if we are testing an API), we will chat about test coverage. Is it adequate? Is there any thing missing? Can we see the tests fail under the expected conditions?

If it’s a front end feature, I’ll check out the code locally and use a different emulator/simulator than what the developer uses. I’ll give the feature a good shake out and check the test coverage. I’ll also test for accessibility if it’s a new front end feature.

Mock Testing

For our mobile app, we are able to do most of our code review testing without ever talking to a backend. The engineers have built some mock servers into out apps, when the app would call an API, our mock server returns a canned response. This helps us test that the UI and the flow hangs together even when test environments aren’t available. If you’d like to read more, check out this article on mock testing for android or this one for iOS.

Build Pipelines

We have different pipelines for different applications. We are using TeamCity as our Continuous Integration tool. Generally all of our unit tests and UI tests will be run. Maybe our contract tests. I have a few other ideas to increase the value from our build pipelines that I’ll talk about in Chaos Testing. If our main builds start failing, we won’t release the software.

Device Coverage

We don’t necessarily focus on doing device testing for each feature that comes through. I try to pick a different emulator/simulator than what the developers do. I always make sure features get tested on a Samsung. Some features, if they are 3 star features from our risk analyst we will spend more time testing on a wide variety of devices. We currently have an on premise mobile device cloud server delivered by Mobile Labs. If you don’t have a device cloud, you could set up your own device farm.

Why Samsung?

Samsung has a wide market saturation and they always do funky stuff to the android UI. The android emulators are awesome at vanilla android. However, most people out there aren’t using vanilla Android :(.

Contract Testing

We are moving towards having contract testing in place that lets us know if an API starts to break, if someone changes the JSON payload in an API our contract will break and someone will know the have more stuff to clean up. We don’t have contract testing for our mobile app yet but some of our downstream micro services are starting to build these. If you’d like to find more, read this article by Martin Fowler.

Test Environment

We have an integration test environment where our code is being constantly deployed into. Sometimes it can mean an API is down because it’s being deployed. We do a lot of our API testing in this environment.

Chaos/Crash Testing

With android there’s this command line tool called chaos monkey. This tool is a UI exerciser, it throws random user input at your UI to try and find where it crashes. I’m hoping to include this in a build pipeline for an overnight build. Run it for a few hours on an android device and see if it crashes. The next night, do the same thing but on a different device/os combination. This will give us reasonable device testing over a sprint. I don’t know of a similar tool for iOS. You can read more about chaos engineering on wikipedia.

Layer Three: Shipping the product feedback loop

Bug bash

A few days before the end of the sprint, our team and invited guests will sit down and do some exploratory testing on the features that have just been built. If anyone wants to explore a new API that’s been built, they can. If they’ve had their head in unit tests lately, they have the chance to explore some of the new UI. You can read how to run a bug bash to find out more. If major bugs are found here we won’t release the software. We might do a mob programming session when we don’t have enough features for a bug bash.

Demo

On the last day of the sprint we will demo our features to a broader audience. Feedback is gathered and turned into Jira items/research for the design team.

Internal release

Then we release to internal staff members. Many other companies call this “eating your own dog food”. This gives people the chance to raise more feedback before we put the product in front of customers. You can read more on wikipedia here.

Beta Release

We can release our app to our high value or digitally savvy customers who want to ahead of the curve. This is a customer engagement strategy as well as a test strategy.

Percentage roll outs

The google play store allows you to do percentage rollouts. Say you rollout to 5% on the new version, monitor production for any new crashes or customers complaining. If it’s all smooth for a few days you can continue the rollout to 50% and then 100%. The google play store allows you to roll back if major bugs do occur. The apple play store has a similar feature.

Monitoring in production

What metrics should be communicated back to the team? How can we respond to issues in production? I like this quote from a 5 minute google talk back in 2007:

Sufficiently Advanced Monitoring is Indistinguishable from Testing

Ed Keyes

Layer Four: Supporting the product feedback loop

Supporting devices

We should support all of the devices that 80% of our market uses. We will be support from Android 6 (marsh-mellow) and from iOS 11. There probably will be some obscure android devices out there that don’t play nice with our app. Android is a beast like that.

Facilitating customer feedback

There will be an easy way for customers to provide feedback in app. I have some ideas on how to make that experience better but there are privacy concerns to consider. We will also be monitoring our google/apple play store reviews for bugs.

Triaging feedback

Someone should be monitoring all of this feedback, attempting to reproduce bugs if customers are facing them and raising them in the teams backlog for prioritisation next sprint.

Soap Opera Testing

Maybe in the future, we could try some soap opera testing with the business? Soap opera testing is a condensed and over dramatised approach to testing. What are the wackiest scenarios our customers have actually tried? How does our system break? You can read more about this exercise here.

Why the layers?

Consider each of these layers like a net. It won’t catch everything, bugs in production will still happen. But when we have all of these feedback loops layered on top of each other, we get a pretty tight net, where hopefully no major issues get into production.

What about auditing or compliance?

Our source of truth is the code, Jira and Confluence. When we have all of it integrated, we can prove we tested a feature thoroughly without too much extra overhead. An auditors mindset and a testers mindset are very similar. Testers are concerned with product risks, auditors are concerned with business risk.

Their main question is, “did you do what you say you do? Did you follow your process?” and, “Is the existing process adequate?”.

Where are your test cases?

Michael Bolton has a 7 part series on breaking the test case addiction. You can read series one here. You don’t need test cases to prove you did adequate testing. They create unnecessary overhead that detract from adding business value.

What else is missing?

Security testing is not included in this test strategy. Neither is performance testing. Getting these included can be challenging. I’m open to your suggestions in how I can incorporate this type of feedback in a timely manner.

What else would you add to your test strategy?

70 days into #100DaysOfLinkedIn

Wow, I’m two thirds of the way through my #100DaysOfLinkedIn marketing campaign. Here is an update of how I’ve adapted and grown over that time. You can read up on the launch of the campaign and a halfway through update too.

2200 connections

Before starting this campaign, I had 1400 connections. I’ve now see this grow to over 2200 at the time of writing this blog. I’ve written to every single one of those 800 new connections. EVERY. SINGLE. ONE. I’m now up to my third version of a template message. Here it is:

Hi ,

How are you? Thanks for connecting. What are some of the challenges facing you these days?

You might enjoy reading my blog on Soap Opera Testing:
https://bughuntersam.com/soap-opera-testing/

Is there anything I can help you with?

Regards,

Sam

It’s short and sweet. Most people don’t respond but I’ve been able to organise a few key meetings with this approach, organise a few testers Meetup events and score a job with a startup.

Reconnecting with Sydney testers

I have around 200-500 QA/Testing professionals based in Sydney in my network. I’ve been reconnecting with them to see what events they are interested in. Here is my template message reaching out to these people:

Hi ,

Have you been to a Sydney Testers event recently? We’ve got a few events lined up that might interest you:

API Testing at ING on the 4th of April https://www.meetup.com/Sydney-Testers/events/259748843/

Performance Testing at the Rockend in St Leonards on the 9th of May

https://www.meetup.com/Sydney-Testers/events/259722603/

I’d greatly appreciate it if you could share those events with any colleagues who would be interested.

If you can’t make it on the day, I will be streaming these meetups through www.twitch.tv/BugHunterSam

What other events would you like to see?

Regards,

Sam

Avoiding Automation

I don’t generally automate these messages because that is against LinkedIn’s terms and conditions. I actually have a Google doc full of these template messages that I copy and paste into LinkedIn and add the person’s name at the start.

5000 connections?

Can I get to 5000 connections? Maybe not by the time I finish this campaign but I will continue to use the techniques learned from this campaign after I finish. If I get to over 5000 connections I will become the most connected software tester that I know.

Test Automation Uni – Day 1

Today I hosted a lovely bunch of keen learners who wanted to put aside some time and do an online course with me. You can check out the event on meetup here. Today’s topic was setting a foundation for successful test automation by Angie Jones. I also streamed the activity and conversations via twitch.tv/BugHunterSam. Here is what my loungeroom looked like:

Chapter 1 – Designing a Test Automation Strategy

  • What is your goal for starting a test automation initiative and what is it that you want to accomplish?
  • Who do you envision participating in your test automation initiative and in what capacity?
  • How do you plan for the execution of this strategy

Chapter 2 – Creating a Culture for Test Automation Success

  • how to get people on board
  • how to help them understand their place in the automation strategy
  • how to enable them to do what’s needed

Chapter 3 – Developing for Test Automatability

The test automation pyramid is a mental model for thinking about what level you should build your automation tests. It’s a little contended because it doesn’t acknowledge exploratory testing but it’s a model that is widely used. James Bach has a blog on the round earth model that could also be used.

Chapter 4 – Tooling for Test Automation

We discuss how to choose the right tools for your initiative. Before choosing your tools, it’s important to consider who will be using them.

Chapter 5 – Future-proofing Your Test Automation Efforts

Without a clear strategy in mind, many teams make the mistake of automating their tests for their current situation. Perhaps you’re just starting out and you have a dozen or so tests that run locally. You don’t see the issues that your poorly written test code can surface.

Design patterns

Become familiar with design patterns that are especially beneficial for test automation projects such as:

  • Page Object Model
  • Screenplay
  • Fluent
  • Builder
  • Singleton
  • Factory
  • Facade

Here is a getting started guide with Page Object Model (POM) architecture with C# and selenium:

Chapter 6 – Scaling Your Test Automation

Writing automated tests that run perfectly against one environment is challenging in and of itself. But what about when you’re ready to scale your one suite of tests to run in multiple environments, browsers, or devices?

LUNCH

On the menu today was Turkish. We had a lentil tabbouleh salad, Turkish bread, felafel, hummus, tatziki and marinated chicken. You should come along to the next event just for the food. I always put on a good spread.

Chapter 7 – Measuring the Value of Your Test Automation

Many automation projects fail due to unrealistic expectations. To avoid this, it’s best to identify expectations early and communicate these expectations to the entire team. What’s your expected Return on Investment?

Bonus Material: Writing readable code

Having readable code is a prerequisite to scaling your product and the organisation behind it. Hard-to-read code not only intimidates your co-workers (and your future self) but also conceals bugs and hurts your team’s velocity, since every modification takes twice as long as it should. This talk shares the principles of writing clear, idiomatic JavaScript code, illustrated with real-world examples.

Hands on exercise

We finished the day with a live code example of getting started with Page Object Model architecture using c# and selenium. I would share the video with you but I was experiencing issues with OBS and was unable to get you a video :(.

Tails of Fail

Today I gave a talk at TiCCA (Testing in Context Conference). The talk topic was tails of fail – how I failed a quality coach role. It’s a story of how I tried out this quality coaching thing but I didn’t pass probation. You can access the slides here. I used slido to manage the questions at the end of the sesion.

At the end of the day, quality coaching can be hard to demonstrate value add.

Will you answer all these questions offline ?

Yes, this blog post is an attempt to answer all of the unanswered questions that were raised. Thanks Richard. First of all, a bit of context that was missed in my intro. I’m currently a Test Analyst at a superannuation company, I don’t technically have coach in my title but I’m also growing my side business where I provide training and workshops for teams in testing skills. This might have caused some confusion with the questions.

What does a quality coach’s typical day look like?

When I was at Campaign Monitor, my day would start with a stand-up and seeing what items needed focus on for the day. The team might have a work item that needed a bit of testing and I’d be available to pair test with that developer if needed. Some days we would run workshops (training for quality champions; developers who wanted to improve their testing skills) or bug bashes (these were generally once a fortnight).

What are the differences between a quality coach and an agile coach and a test coach?

An agile coach is a facilitator, often scrum certified (but not always). They are usually more focused on helping the team collaborate more effectively over improving the teams quality/testing practices. I don’t see much difference between a test coach vs a quality coach. You can use the words that make sense in your context.

Are there any drawbacks to using a quality coach practice?

Yes, when you are encouraging people who prefer to build things workout their testers mindset you aren’t going to get as focused attention as someone who has spent their career practicing their testing craft.

Also, you might have some really technical testers who aren’t interested in coaching/leadership skills. You shouldn’t expect everyone to want to become a coach and that’s fine too.

What are the benefits to the organisation of the assistance/coach/advocate model?

If your company believes that quality is a team responsibility a coach can help lift the testing capabilities of a team. If you need a bit of focus on quality (maybe you have lots of customers complaining about bugs and it’s costing you big $) but you don’t know how to get your engineering teams to prioritise bug finding as well as build new features a coach could help here. There isn’t a great deal of training out there in how to be a good tester, it’s not as easy as sending your devs off to a 3 day course and bam they are master bug hunters.

If everyone is responsible for quality, is anyone really responsible for quality?

You could always say the CEO or CTO are fundamentally responsible for quality. Maybe have a Chief Quality Officer (CQO)? Maybe they’d just become a scapegoat for all of the problems you face in production? The testing teams themselves aren’t responsible for quality if they can’t easily build quality in either.

What is a good team to quality coach ratio?

Depends on the team/company. When I was at Campaign Monitor we had 2 testers to roughly 50-ish engineers. Hence why we were using the quality champion model to help get more quality reporting from teams. We physically couldn’t sit with all 6 teams at the same time to understand their pain points. I’d prefer a 1 coach to 1-2 cross functional teams. Being embedded and focused on one team of roughly 8 people would work for me.

What are the challenges you faced while quality coaching?

Clearly articulating how I add business value that aligns with my own intrinsic motivations and interests. I don’t think I’ve struggled with convincing developers they need to do more of their own testing.

Visual Risk & UI Automation framework

Have you wanted to start with automation testing and not known where to begin? Or maybe you have 100’s or thousands of test cases in your current automation pipeline and you want to reduce the build times. Here I will walk you through one way you could consider slicing up this problem. Using examples from Tyro’s banking app (I use to work on their mobile iOS team).

Break into flows

Analyse your app/site/tool and brainstorm the main flows that people will take through it. I picked 6 flows using tyro as an example app. Next I numbered them.

1. Registration

Registration is a pretty common feature, you might also set a 2 factor authentication, a pin and a password for the account (especially if it’s a bank account)

2. Transfer Funds

If you have a bank account, it’s highly likely you want to access the money in it at some point

3. View Transaction

You might want to check if that bill was paid correctly or if the last transfer was processed

4. Contact Us

Something not quite right? send us a request and we will give you a phone call at a convenient time

5. Change Pin

When was the last time you changed the pin for your mobile banking app?

6. Log in

I’d say this is a pretty common feature

Mapping those flows to a risk board

Draw a graph, put frequency of use on the x axis down the bottom; things that are more used will be on the right hand side. On the vertical y axis put impact if broken. This is from a person point of view, how much would they care if that feature was a broken? From a business point of view you may have a different understanding of risk and that’s fine two. We will go into how to reflect that later.

Add your flows

We have our 6 flows to the right hand side of our graph, we’ve also broken our graph into 3 areas

Move the flows to your graph

It helps to pair on this exercise to help build up a shared understand. Do your designers and engineers have the same understanding of risk as you do? It’s ok if your answer is different to mine, we all have a different context and understanding.

Reflect other elements of risk

You might want to reflect other elements of risk such as security, financial, regulatory and anything else you can think of. At the end of the day this is only a 2 representation of risk and risk is a little more complex than these dimensions we put here.

Neat, what’s next?

If you are thinking, well that’s cool and all but what does that have to do with automation testing? Then please continue reading. You could use this board to decide which tests you should focus on building/refactoring next (hint, the stuff with 3 stars is pretty important). You could also use this to priortise your performance testing efforts. I took this board to our planning sessions to talk about new features and it helped with deciding how much automation/testing effort we may need. At the end of the day, your software will be more complex than this example.

Here is the actual board I used at Tyro with a bit more detail:

I then broke down each flow into a test case, and grouped similar test cases into a barebones automation test suite. You can also use this approach to generate exploratory testing ideas for each screen in your flow.

I also run this as a lunchtime 30-45 minute workshop exercise. Book me in for a lunchtime brownbag if you are based in Sydney (I can do remote too).
