They're usually small and fast, isolating Local tests execute on your development machine or a server, so they'reĪlso called host-side tests.Instrumented tests are usually UI tests, launching an app and The app is built and installed alongside a test app that injects commands and Instrumented tests run on an Android device, either physical or emulated.You can run tests on an Android device or on another computer: However, the most important distinctionįor app developers is where tests run. Medium tests are in between and check the integration between two orįigure 1: Test scopes in a typical application.Same time, such as a whole screen or user flow. End-to-end tests or big tests verify larger parts of the app at the.Unit tests or small tests only verify a very small portion of the app,.Tests also vary depending on size, or degree of isolation: Compatibility testing: does it work well on every device and API level?.Accessibility testing: does it work well with accessibility services?.Performance testing: does it do it quickly and efficiently?.Functional testing: does my app do what it's supposed to?.Subjectįor example, there are different types of tests depending on the subject: Mobile applications are complex and must work well in many environments. Gives you more actionable feedback about your app earlier in the development That perform tests for you, which is faster, more repeatable, and generally However, manual testing scales poorly, and it can be easy to overlook You might useĭifferent devices and emulators, change the system language, and try to generateĮvery user error or traverse every user flow. You can manually test your app by navigating through it. By running testsĪgainst your app consistently, you can verify your app's correctness, functionalīehavior, and usability before you release it publicly. Testing is an integral part of the app development process. This page outlines the core tenets of testing Android apps, including theĬentral best practices and their benefits.
