You got an amazing idea…

You nailed the UX…

You got a beautiful UI…

And you are all set to start developing your app.

The fun, exciting and explorative phases are done and you are moving into execution mode. You want an incredible user experience to make your app the next big thing. What does it take? Testing, testing, testing…

Things to consider upfront (before you even start to develop)

Testing and Quality Assurance (QA) is a time consuming and sometimes dull task. But it’s critical to do in-depth testing in order to deliver an app your users will love 💖.

Before you start developing your app consider the following:

  • Which platforms does the application need to support? Web, mobile, tablet, desktop?
  • Web: Which browsers need to be supported? Chrome, Firefox, Safari, Internet Explorer, Edge etc.?
  • Mobile & Tablets: iPhone and/or Android? iPad and/or other tablets?
  • Desktop: Windows app and/or Mac app?
  • Compatibility: Are you only going to support the latest released OS and browser versions, or does it need to be compatible with older versions?

Assume you need to support 5 browsers + iPhone + Android, you need backwards compatibility on all platforms and to support different devices; then you’ll see how the testing effort quickly scales up.

Overall Test Approach

Follow these 5 tips to speed up testing and quickly find critical bugs:

  1. Carry out cross-platform testing: Login with different users simultaneously on all supported platforms. Use both simulators and physical devices. You can now start testing.
  2. Check the most important functionality, the overall flows etc. Variations, combinations, details and edge cases can be checked later.
  3. Do everything that you think you shouldn’t be allowed to do!
  4. Try to make the system crash!!
  5. And of course check spelling, UI, design, alignment etc.

You can of course test a lot with simulators. But remember to test on physical devices as well. They sometimes provide slightly different results 😉

In-depth QA Tests

Here’s a detailed list of things to look out for in your current or next project.

It’s a checklist for all members involved in your app development. Developers (backend + frontend), Designers (UX + UI), QA, QC, Project Managers, Product Owners and Support.

  1. Sign up: Create account with email.
  2. Sign up: Activate account via link in email.
  3. Sign up: Create password. Which rules apply to the password? Small and capital letters, numbers and special characters, minimum length etc.
  4. Login: Successful login.
  5. Login: Auto-login when opening the app.
  6. Login: Failed login using incorrect username and/or incorrect password.
  7. Login: Lock account on too many incorrect login attempts.
  8. Login: Reactivate account if it has been locked.
  9. Login: Test social logins like Facebook, Google, LinkedIn etc.
  10. Login: Test single-sign login.
  11. Login: Test two factor authentication.
  12. Log out: Log out from the application.
  13. Log out: Log out of all devices.
  14. Profile: Change password.
  15. Forgot password: Verify that you receive a password reset email or SMS code and that the updated password works as expected.
  16. Onboarding: Test all variations of the flow. E.g. if the onboarding splits up into different routes depending on a choice, if different templates/groups can be selected etc.
  17. Onboarding: Check that you can’t proceed if the user needs to select a minimum number of topics to follow.
  18. Onboarding: What happens if the user stops in the middle of the flow?
  19. Onboarding: Test the email onboarding sequence after sign up. Maybe you use services like Drip, Mailchimp or ActiveCampaign?
  20. Empty state: Does the application look properly (and good) when no content is shown? What happens when the first item is added?
  21. Empty state: Delete all content and check the empty state.
  22. General: Is each field in the application the correct type? Single line of text, multiple lines of text, numeric, yes/no, dropdown, choice, lookup, date, time, person, calculated value, link etc.
  23. General: Can the field be edited or is it a view-only field (locked for editing)?
  24. General: Does the field have a minimum or maximum length? Does it require an exact number of characters (like credit card details where you need to provide an exact number of characters)?

  48. General: Can follows/likes be unfollowed/unliked? Is it dynamically reflected for other users.
  49. General: Check business rules if you have fields which are dependent on each other. E.g. if values filled in one field narrow the options available in the next field. Go back and change a previous field. Verify that dependent fields are updated/cleared.

  227. Delete account: Ultimately, check that you can delete your account.

Speed vs. Quality

If you ship often and your app is feature-rich you’ll probably need one or more full-time QA engineers to ensure that you continouosly deliver a high quality app.

Move fast and break things. This was Facebook’s original motto. It may be a fine approach for early startups without too much traction but you (and your customers) need stability as you mature.

This is why Facebook changed their motto to Move fast with stable infrastructure since fixing bugs was slowing down development.

Facebook’s original and new motto.

How to help your engineers?

There’s nothing more frustrating for your developers if you say “it doesn’t work” without providing any details.

Provide the following information to make your developers happy. It will of course also speed up the time to fix the observed issue 😉

  1. Record the time the issue happened.
  2. Make sure you can reproduce the issue consistently.
  3. Describe the exact steps you follow.
  4. Open your browser and press F12. Then reproduce the issue. Open the Console and Network tabs and provide the results to the developers. N.B. Clearing the data in the Console and Network before you reproduce the issue is a good idea.

Manual or Automated Testing?

If you build a cross-platform solution you’ll have a huge amount of test combinations. So you need to develop your test strategy wisely. Do the right amount of tests — not too little — but also do not test all combinations.

If you are in QA but doesn’t have any coding experience, it might be worth talking to the engineers since some of the things you think is important to test might be irrelevant.

You can setup automated test tools — or carry out manual test. What’s the best choice depends on the maturity of the product and the size of your company.

Automated test tools sounds great, but you need a really mature product before it makes sense. You need to know that core features, UI and UX is not going to change for a long period. Otherwise, you’d constantly have to update the test script.

Automated test tools also doesn’t spot things which are not right. It can be softer things like UI, spelling, alignment etc. which is important for the user experience.
