Top Testing Strategies in Mobile App Development
Rob Turner

When a mobile app goes through the development stage, it is critical that developers perform various tests before the app is launched. Here are seven of the top testing strategies you should perform.

Cross-platform Testing

If your mobile app will be interacting with other software across multiple platforms, it is essential that your app works correctly on all of them.

A cross-platform mobile app testing strategy, which is performed on all relevant systems, can catch any bugs or failures to ensure your app is fully functioning.

Developers can use various automated cross-platform testing tools, which can run tests in numerous browsers and browser versions.

Visual Regression Testing

To catch visual bugs, a visual regression testing strategy needs to be employed. Developers can use automated visual regression testing tools to check for style problems and issues concerning the visual layer of a mobile app, such as hidden buttons, CSS issues, and overlapping modules.

When test scripts are used, they can miss visual issues because they solely interact with the underlying code. So, automated visual regression software is a much better solution.

Feature Functionality Testing

The features of a mobile app are built into both the app and the devices using the app, so the interactions must be carefully noted.

You can thoroughly test interactions with a feature functionality testing strategy. However, do not waste time running functional tests across lots of different mobile devices.

Instead, test on just one device and then use compatibility testing to ensure the app’s features function correctly on different devices.

Front-end Testing

Front-end testing verifies the user-facing interface of your mobile app. The process checks the efficacy of the app’s functionality on the server and the database.

Developers need to have knowledge regarding the requirements related to user experience, but they do not need to have knowledge about the database and the back-end mechanics. A front-end testing strategy comprises several individual tests, such as performance checks, app file updates, and regression tests.

Back-end Testing

Back-end testing checks your mobile app from the server-side. Also known as database testing, back-end testing basically tests the application layer and the database layer of your mobile app. So, it is performed on the user interface and the database.

Application Flow Testing

A great mobile app brings together different elements, like visuals, features, functionality, and content. When there is a strong visual flow between those components, users will be able to use your mobile app much more easily.

Therefore, testing the flow of the architecture of your mobile app is crucial. It enables you to discover design elements that impede users from completing tasks.

Security Testing

Your mobile app not only needs to function correctly on different devices and browsers and have excellent user functionality. It also needs to be secure.

Of course, the more data that is sent back and forth via your app, the more problematic security concerns will be. If your app is released but is not fully secure, major data breaches can happen, which can cost companies millions of dollars and have huge repercussions to their reputations.

Therefore, it is imperative that you perform security tests and are satisfied with the results before launching your mobile app. You should test for any kind of data leak and ensure no part of the web data is vulnerable.

Summing Up

While there are several other tests you can perform to ensure your mobile app is as good as it can get, the above tests are the most important.

So, to recap, the top testing strategies in mobile app development are:
  • Cross-platform testing.
  • Visual regression testing.
  • Feature functionality testing.
  • Front-end testing.
  • Back-end testing.
  • Application flow testing.
  • Security testing.
