Top Mobile App Testing Methods to Include in Your Testing Plan

Keeping these core techniques in mind when creating your app testing plan is important for keeping your users coming back.

Did you know that 24 percent of users abandon apps after only one use? Keeping users coming back to your app is a challenge, and you need to address it by developing an app that fulfills a purpose, keeps users engaged, and is free of bugs.

This is why testing is crucial to developing a successful app. Here are a few methods to consider when developing a relevant testing plan for your app.

Perform Unit Tests Throughout the Development Process

The purpose of a unit test is to make sure a small unit of code functions properly. Developers can write these tests for functions, classes and other small units. It isn't possible to put every single line of code through a unit test, but these tests should be performed on as many important elements as possible.

Unit tests can be integrated into the development process so that the code for each important feature of the app is tested before developers move on to the next step.

Replicate Unusual Scenarios With Manual Tests

How will your app react when something unusual happens? You should put your product through a series of manual tests to see how the app reacts when the phone battery dies, when a call comes through, when a user launches another app in the background, or when incorrect data is entered. Focus on memory leakage tests, interrupt tests and load tests to see how quickly the app launches in different scenarios. Try recreating different scenarios with hardware features, including acceleration, location, and pressure sensors. You should also conduct manual tests for installing the app, updates and uninstalling the app.

It is possible to rely on auto tests to recreate these unusual scenarios, but this means more time will be spent on coding tests. Unless you plan on putting the same features of the app through these auto tests several times, manual tests will probably make more sense.

Plan Comprehensive System Tests

As you get closer to a finished product, your app should be tested on as many different devices as possible. Tests should be performed in different languages as well.

If you are developing an app for a client, they will probably want to put the product through an acceptance test at this stage to see if the app meets their expectations or not.

Don't Forget Network Tests

This is an often overlooked aspect of app testing. Network connections can really impact the user experience. Create testing scenarios with varying connection qualities and see how it impacts load time and overall performance. Test your app on LTE, 3G and Wi-Fi as well as during network transitions.

Develop a Security Testing Plan

Make your app safer by identifying potential weaknesses, such as the app requesting permissions it doesn't need or storing unnecessary data. Think about adding some security features, such as relying on device ID, certificates, and encryption.

You will also need to go through the log files to make sure the app isn't performing any unauthorized actions, and go through certification testing to ensure the app meets compliance requirements before submitting it to the app store of your choice.

The best defense against bugs is to develop a comprehensive testing plan and to implement it throughout the development and design process. You can never do too many tests if your goal is to develop a quality product that delivers an optimal experience for users.
