| # Flicker Test Library |
| |
| ## Motivation |
| This set of tests use the flickerlib from `platform_testing/libraries/flicker` to execute a set of common UI transitions to detect discontinuous or unpredictable behavior. |
| |
| The tests are organized in packages according to the transitions they test (e.g., `rotation`, `splitscreen`). |
| |
| ## Adding a Test |
| |
| By default, tests should inherit from `TestBase` and override the variable `transition` (Kotlin) or the function `getTransition()` (Java). |
| |
| Inheriting from this class ensures the common assertions will be executed, namely: |
| |
| * all regions on the screen are covered |
| * status bar is always visible |
| * status bar is at the correct position at the start and end of the transition |
| * nav bar is always visible |
| * nav bar is at the correct position at the start and end of the transition |
| |
| The default tests can be disabled by overriding the respective methods and including an `@Ignore` annotation. |
| |
| For more examples of how a test looks like check `ChangeAppRotationTest` within the `Rotation` subdirectory. |
