The default Android Bitrise configuration runs Android Lint and Unit Tests. To run UI tests we need to add the build step “[BETA] Virtual Device Testing for Android”

Unit Tests

1. Default Bitrise build step “Android Unit Test”

2. Unit tests results are output into “App & Artifacts” tab.

Extra:

By default, Bitrise zips the test results for unit tests. To generate Unit Tests HTML results report.

1. We need to write a bash script to move the HTML report to the Bitrise output directory.
2. Add step “Do anything with Script”, and copy paste below Linux command. Linux command “mv” moves the HTML file to $BITRISE_DEPLOY_DIR location.

#move results to bitrise deploy dir and rename file
$mv /bitrise/src/AppName/./build/reports/tests/testGoogleFlavorAppNameFreeFatReleaseUnitTest/index.html $BITRISE_DEPLOY_DIR/Unit-tests-results.html

3. Now Unit tests HTML report is moved to Bitrise tab “Apps and Artifacts”.

UI tests

UI test (Espresso tests) are run in Firebase Test Lab (FTL), if you are familiar with FTL is a similar configuration. We need to generate Debug and Test APKs to run UI test on FTL framework.

1. Open Bitrise workflow.

2. Build Android debug build APK and Android Test APK. To generate Test APK we need to add the build step “Gradle Runner”.

3. Add build step “[BETA] Virtual Device Testing for Android”

4. Select Instrumentation Test tab, and configure FTL

5. Run. We get UI tests results in the “Test reports ->See more tab”

Android Lint

Is configured by default.

Bitrise generates HTML results report:
