Android Application Development – Few Basic Still Most Important Things to Test

Testing though is the last step of an Android application development cycle, is the most important part of the whole process. It is only through testing that an Android developer can judge the quality of the application developed. And it is only at this stage that developers can know if the application they have developed is functioning as required or not, if not then they have the chance to rectify the error before the application is delivered to clients.

Android application testing is huge and includes lot many things, however it is as important to know what to test as to know the process of testing for Android app development. Here we have made an attempt to highlight the behaviors or situations to test even at the unit test level.

Change in Device Orientation

Android enabled devices available now-a-days have the ability to detect changes in the orientation data and use the data to automatically rotate the display of images and applications either in “landscape” or “portrait” view. Android app development when done needs to be able to adjust to Android device’s orientation. Hence you need to check if the screen is re-drawn correctly; custom UI code can adjust to orientation changes; how well the application maintains its state; UI information should not be lost and application placing in the current transaction for device orientation.

Change in Configuration

When the default configuration of an Android device changes it results in the destruction of the default behavior of the application and restarting of the foreground activity. This might be affected even in case of simple changes in device configuration like change in system language or change in keyboard availability. It is thus important to check that the application is still able to maintain its UI and transaction state, even when device configuration changes. It is also crucial to check that the application automatically updates itself to be able to correctly respond to the changed configuration.

Battery Life

Why are mobile devices mobile? Simply because they use battery power, which makes them independent of relying on switch boards to be able to function. They are of no use, if there battery goes off. Hence Android app development should be done to develop application which will consume minimum battery or else users might be reluctant to use it.

Reliance on External Resources

Mobile accessories and its features enhance mobile device’s utility, Android application development is often done considering these external resources. Obviously the application will work all well when all the external resources needed for its smooth functioning are available. But that is not all, it is important to check how the application behaves in the absence of any of the resources needed for its functioning. For example if your application relies on network availability then it should be able to notify the user in case if network is not available.
