HOW TEAM TEST MOBILE APPS

HOW TEAM TEST MOBILE APPS

by Zubaer khan

“Mobile first” is the motto these days for many companies. However, being able to test a mobile app in a meaningful way is very challenging. On the Google+ team we have had our share of trial and error that has led us to successful strategies for testing mobile applications on both iOS and Android.

General 

• Understand the platform. Testing on Android is not the same as testing on iOS. The testing tools and frameworks available for each platform are significantly different. (e.g., Android uses Java while iOS uses Objective-C, UI layouts are built differently on each platform, UI testing frameworks also work very differently in both platforms.)
• Stabilize your test suite and test environments. Flaky tests are worse than having no tests, because a flaky test pollutes your build health and decreases the credibility of your suite.
• Break down testing into manageable pieces. There are too many complex pieces when testing on mobile (e.g., emulator/device state, actions triggered by the OS).
• Provide a  hermetic test environment for your tests. Mobile UI tests are flaky by nature; don’t add more flakiness to them by having external dependencies.
• Unit tests are the backbone of your mobile test strategy. Try to separate the app code logic from the UI as much as possible. This separation will make unit tests more granular and faster.
