CTS tests for CompanionDeviceManager are split into 2 modules: CtsCompanionDeviceManagerCoreTestCases (a.k.a. “Core Tests”) and CtsCompanionDeviceManagerUiAutomationTestCases (a.k.a. “UiAutomation Tests”).

The core difference between the two test modules is that CtsCompanionDeviceManager_Core_TestCases does NOT use UiAutomation which makes it:

• faster
• suitable for to run on NFFs
• less prone to flakiness
• better suitable to run in PRESUBMIT.

CtsCompanionDeviceManager_UiAutomation_TestCases, on the other hand, uses UiAutomation in order to test CDM flows end-to-end and is (at least for now) designed to run only on the mobile form-factor and requires a discoverable BT device nearby.
