CTS Verifier for Instant Apps

CTS Verifier for Instant Apps increases Android Compatibility test coverage for Instant Apps by using CTS Verifier to test features that can't be fully automated due to OEM- specific UIs, such as system UIs.

Requirements

Before running CTS Verifier for Instant Apps, ensure that you have the following equipment:

  • Android device that has verified Android API compatibility by successfully passing the CTS. This is the device-under-test (DUT).
  • Linux computer with USB 2.0 compatible port. All connections to the DUT are through this port.

Installing Instant App on DUT

CtsVerifierInstantApp.apk and the CTS verifier are included in android-cts-verifier.zip, which can be found by logging in to the Q-EAP dashboard.
