Testing

The following table includes a set of test cases that you can use in your own test plan. The test cases cover a wide array of common scenarios that Android apps should be prepared for if they are expected to run on ChromeOS devices.

Test type	Test case	App scenario	Success case
	Find app in Play Store	All	App exists in Play Store, accessed from a Chromebook (no issue if working as intended). NOTE: Flags in your manifest⁠ may cause the app to be unavailable, depending on the hardware in the ChromeOS device. This test is best run on clamshell devices, as they most accurately represent the hardware profile of most devices.
	Install app	All	App installs on the Chromebook with no issues
	Clamshell: Launch app	All	App opens without crashing, hanging, or throwing ANR (app not responding). App content is upright.
