ew-cli 0.9.17

• Added --shard-target-runtime option to ew-cli. It’s a new sharding mode where you specify the overall runtime instead of the number of shards. E.g. a 10-min test suite will spawn 5 shards and finish around 2 minutes when invoked with --shard-target-runtime 2m
• When running with --num-flaky-test-attempts we no longer re-run whole shards but only the tests that failed. You can revert to the whole behaviour by adding --flaky-test-repeat-mode all.

emulator.wtf web app

• The LLM-powered analyze test result button now streams the reply on the fly instead of being stuck for multiple minutes

GitHub action emulator-wtf/run-tests@v0.9.5

• Fixed --display-name errors when running the action
• The emulator-wtf/run-tests GitHub action now depends on the pinned versions of the emulator-wtf/setup-ew-cli and emulator-wtf/invoke subtasks. If you depend on an exact version (e.g. emulator-wtf/run-tests@v0.9.5) then you’ll be using fixed and deterministic versions of all the emulator.wtf GitHub Actions.

gradle-plugin 0.13.2

gradle-plugin 0.13.1

ew-cli 0.9.15

• Added --proxy-host, --proxy-port, --proxy-user and --proxy-password options to configure the use of a https proxy when hitting emulator.wtf APIs

gradle-plugin 0.13.0

• Bumped default ew-cli to 0.9.14
• You can now filter what tests to run with the testTargets option. Use something like testTargets = 'class foo.bar.Baz' to only run tests in the foo.bar.Baz class. See the full options here: https://developer.android.com/reference/androidx/test/runner/AndroidJUnitRunner#typical-usage

GitHub action emulator-wtf/run-tests@v0.9.3

• Bumped default ew-cli to 0.9.14

ew-cli 0.9.13

• ew-cli now prints errors in a {"error": "some error message..."} object to standard out when running with the --json flag

gradle-plugin 0.12.1, 0.12.2

• Added a printOutput option to the Gradle plugin which will print the output of the ew-cli command to standard out. This is useful for debugging issues with the plugin without having to resort to the noisy --info flag.
• The Gradle plugin now shuttles errors from ew-cli correctly, displaying them at build failure.
• Bumped default ew-cli to 0.9.13

GitHub action emulator-wtf/run-tests@v0.9.2

ew-cli 0.9.11

gradle-plugin 0.12.0

• Gradle plugin no longer adds the maven.emulator.wtf repository if repositoryManagement is used from the settings.gradle or settings.gradle.kts file.
• Added a project property (wtf.emulator.addrepository=false) to bypass adding the repository completely, even if the plugin would add the repository manually. When using this you should either add the https://maven.emulator.wtf/releases/ repository manually or provide the ew-cli binary in some other way.

emulator.wtf web app

• Scaleup plan upgrade is now available to all users via self-service. You can upgrade to this plan from the billing page in the emulator.wtf web app
• Added GitHub SSO support. Your GitHub team members can now access your emulator.wtf organization directly without having to go through email invites (scaleup plan only).

ew-cli 0.9.10

• The --test-targets-for-shard option now supports all the same operators as --test-targets: class, notClass, package, notPackage, annotation, notAnnotation, size.

emulator.wtf web app

• Fixed logcat not displaying correctly for timed out tests
• Results page now jumps to the first timeout when both timeouts and failures were encountered in a test run

• Added an option to log in with GitHub OAuth to emulator.wtf web UI.

• Fixed PR comments not showing up for GitHub Actions builds triggered with the pull_request option.

ew-cli 0.9.9

This is useful for CI systems where you want to save build minutes by running emulator.wtf in parallel with other tasks.

gradle-plugin 0.11.0

• Added async option to Gradle plugin which will make it return immediately after starting the test run. The test results will be posted back to GitHub when GitHub integration is used.
