The mobile app market is unabashedly thriving. With countless companies releasing new apps every day, it’s increasingly important for your app to stand out from the rest. A key differentiator is app quality: your app must be bug-free and provide users with a pleasant experience. But how to get started with mobile app testing? Here comes a mobile app testing checklist to assist you in this endeavor.
Before you start testing, you need to define the how, what, and when. Unfortunately, there’s no one-size-fits-all solution for this, and we recommend that you take the time to clarify the following points:
- Test automation. What do you need to test manually, and what can you automate? As a rule of thumb, consider automating tests that are repetitive, time-consuming, or too tedious for a human tester.
- Test prioritization. You can hardly test everything, so you need to assess and prioritize tests to meet your minimum quality standards.
- Test targets. You need to test your app on different devices and OS versions. Create a list of platforms and prioritize your users’ most popular platforms.
Consider using services like AWS Device Farm so you don’t have to set up a test infrastructure yourself.
- Testing tools. Depending on your use case and whether you’re developing for Android or iOS, you have many tools available. For example, try Repeato for automating UI tests and Cucumber for BDD-style tests. You may also want to use a test case management tool like Testrail and track issues with Sentry.io. Experiment to find the right tools!
Functional testing ensures that all of your app’s features work as expected on different platforms, helping you verify that the app meets your implementation requirements. Take this into account:
- Device functionality. Test the required device capabilities on various platforms and ensure functionality on different viewports, screen sizes, and orientations.
- Integrations. Ensure that all service integrations such as GPS, payment functions, or social media are working correctly.
- Everyday use. Test app behavior in everyday situations like answering a call, switching apps, receiving and opening a message, resuming the app after a call, etc.
Performance testing helps you assess your app’s responsiveness, scalability, and speed under different circumstances. Note that this involves much more than just making sure the app loads quickly:
- Must-tests. Be sure to test your app under different traffic and stress levels. Test how long it takes to install, launch, and uninstall your app and how it behaves when the battery’s low.
- Network conditions. Most apps require an Internet connection to be fully usable. So your app needs to behave appropriately under various conditions such as changing networks, different connection states, and network types such as 2G or 5G.
We use mobile apps for everything from creating simple to-do lists to managing our bank account. Users trust that their data’s safe and that your app doesn’t open a backdoor for malicious attacks. Consider the following points for your mobile app testing checklist:
- Data transfer and storage. Test the security of APIs, databases, and local storage to prevent deadlocks and data loss. Encrypt sensitive data and use SSL for data transfer.
- Input validation. Ensure that outsiders cannot compromise your databases or code via form inputs.
- Advanced security features. Use and test facial recognition or fingerprint functionality on modern devices. The same goes for two-factor authentication and other authentication technologies.
Your mobile app’s users are diverse, and they may have impairments that prevent them from using your app. Not only is it morally right to make your app usable for all, but you may also be required by law to meet accessibility standards. Here’s what to consider when testing:
- color ratios
- font sizes
- speech recognition
- screen readers
- assistive technologies like VoiceOver or TalkBack
All points in our mobile app testing checklist are critical to the user experience (UX). Because only a well-rounded app will deliver the look and feel you want. Here are a few additional considerations for excellent UX:
- Localization. Your app must provide consistent quality regardless of the current language. To test this, you may need to bring a native speaker on board.
- UI elements. The design of your app also plays a big role in differentiating it from other apps. Test all UI elements and how they respond to different user interactions.
- Structure. Review the hierarchy and navigation of your app. Does it make sense? Is it convenient and allows the user to move seamlessly from point A to point B?
- Copy. Text must be clear and understandable, regardless of length. This is especially true for button labels, error, and success messages – make sure they’re clear and readable.
Thorough testing can ensure that your mobile app is high-quality and provides users with a flawless and enjoyable experience.
So what’s next? Make this mobile app testing checklist your own by adapting it to your use case. This way, you’ll be on the right track to developing a successful testing strategy for your mobile application.
