Changelog

gradle-plugin 0.0.13

• The emulator.wtf Gradle plugins are now fully cacheable, even when using a remote cache.

• Fixed a race condition where sometimes API 24 emulators wouldn’t start properly
• Added 23.88.5.162 to our outbound IPs

• Emulators are now always in the UTC timezone
• Fixed an issue where emulator clocks were sometimes off by months, failing tests relying on SSL cert validity periods

Launched emulator.wtf web app to help you with:

• inviting more users to your organization
• managing the access levels organization members have
• creating and rotating API tokens and see their usage
• tracking your usage over time
• configuring details like credit-card billing

gradle-plugin 0.0.12

• The Gradle plugin now picks up isolated Android test (com.android.test) subprojects. When using these make sure the targetProjectPath is configured in the android {} block.

ew-cli 0.0.48

• ew-cli now supports capturing a video recording of the test - pass both --record-video and --outputs-dir, a recording.mp4 file will be saved per device-job combination

• All network traffic from emulators now originates from these IP addresses:

  • 148.251.112.247
  • 176.34.140.8

  See the documentation for further details and machine-readable endpoints for getting these.

• Created a separate documentation page: https://docs.emulator.wtf

• 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

• 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.

• Fixed use of androidx test services to capture screenshots

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

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

• 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

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

• Added --json output flag to ew-cli to get machine readable output

• Fixed collecting test coverage data from a variety of API versions

gradle-plugin 0.0.7

There’s now a Gradle plugin that wraps ew-cli. Read more here.

ew-cli 0.0.25

• ew-cli now exits with a non-zero exitcode when started with unknown input arguments. Thanks to @ubiratansoares for reporting the issue.

run-tests v0.0.4

Fixed two issues with the emulator-wtf/run-tests@v0 GitHub action:

• v0.0.3 always crashed due to a misplaced line

Thanks to @ubiratansoares for noticing and sending in PRs for these issues!

ew-cli 0.0.24 released

• Added --num-shards command line flag for sharding. It acts similar to --num-uniform-shards but instead of assigning shards randomly it spreads the tests evenly between shards by test count so that every shard has roughly the same number of tests.

• There’s now an official GitHub action to run tests with emulator.wtf. Read more here.

• emulator.wtf now supports version=30 device configurations and the new ATD (Automated Test Device) images. These images are specifically optimized for running automated tests by disabling some system apps and background services. Read more about ATD images here.

  Complete list of new combinations added:
