Emulators

• Added API 24 emulators

  Complete list of new combinations added:

  • device=Pixel2,version=24
  • device=Tablet10,version=24
  • device=NexusLowRes,version=24

• Fixed rendering of result links in GitHub Action logs by switching token format

ew-cli 0.0.47

• Added APK and input file caching to tests - ew-cli will skip uploading files if they have been recently added, enabled by default for 1h. Use --no-file-cache to disable and --file-cache-ttl <duration> to control the behaviour.
• Added new --prepare flag that only uploads files to populate cache but doesn’t trigger any tests.

Test execution

• Fixed use of androidx test services to capture screenshots

Test execution

• Fixed tests crashing with more complex environment variables due to improper escaping

ew-cli 0.0.45

• Added support for running library tests without an app apk. Use the --library-test parameter instead of --app and --test to test library modules.

Emulators

• Added Android Automated Test Device (ATD) images with API 31. Read more about ATD images here.

  Complete list of new combinations added:

  • device=Pixel2Atd,version=31
  • device=Tablet10Atd,version=31
  • device=NexusLowResAtd,version=31

ew-cli 0.0.44

• Fixed: ew-cli no longer prints errors with Zulu 11 JDK

Test execution

• Fixed: timed out tests now emit full logcat, pulled dirs, coverage data and an (incomplete) JUnit test report

results.emulator.wtf web app

• Fixed: tests running for longer than 1 hour failed with a 404 error
• Fixed: shards are now always ordered by index in results web link

ew-cli 0.0.43

• timeout status is now printed properly
• the results link is now included in the JSON output under the resultsUrl field
• fixed printing out failing shard combinations

ew-cli 0.0.42

• Added results link at the end of the run, enabling to view logcat and failing tests in a web browser.

ew-cli 0.0.41

• Added support for pushing additional files into the /sdcard or /data/local/tmp directory using --other-files.

ew-cli 0.0.40

• Added support for specifying test targets manually via --test-targets-for-shard. Especially useful if you have your own in-house scripts for sharding.

ew-cli 0.0.39

• Improved --help output of ew-cli
• Added support for reading command-line arguments from YAML files. Read more here.

ew-cli 0.0.38

• Added support for --timeout <duration> parameter to cancel test execution when it takes too long. Defaults to 15m (15 minutes).

Test execution

• Fixed ew-cli sometimes getting stuck if the test failed immediately, e.g. when using an unsupported model

Test execution

• Fixed test coverage not working on version=29 emulators
• Fixed long-running tests (1+ hr) getting stuck completely

Emulators

• Added two new device models: Tablet10, Tablet10Atd representing 10" tablets with landscape orientation and a resolution of 1920x1200.

Note: ATD models are still only available for version=30 emulators
