Android unit test

Run a unit test

Unit testing is useful if you want to verify individual code blocks, catch bugs or prevent crashes as early as possible.

This tutorial tells you how to run a unit test against your app and how to generate test reports using your primary workflow.

Luckily, your Android primary workflow already contains the Android Unit Test and the Android Lint steps which are responsible for performing unit test on your build.

Note

If you use custom steps or scripts, our Deploy to Bitrise.io step by default deploys files/build artifacts from the $BITRISE_DEPLOY_DIR directory, so make sure that you move the generated app there, or set the deploy directory or the file path input of the step to point to the location of the files/build artifacts. Please note, that if the specified path is a directory, then every file in that directory will be deployed. If there are subdirectories in the specified directory, they won't get uploaded! You can upload a directory's content recursively, if you use the Compress option, which will compress the whole directory including every subdirectory. And finally, if you specify a file path, then only the specified file will get deployed.

Generate test reports

The Android Unit Test step generates and exports unit test reports into the $BITRISE_DEPLOY_DIR folder. Then the Deploy to Bitrise.io step exports those reports from the $BITRISE_DEPLOY_DIR folder to the respective build's APPS & Artifacts tab on bitrise.io. You can view or download those reports to your local computer.

Troubleshooting: Failed build

If your build has failed running, click on Download logs. In the last lines of your Step log, you can view the error message and fix the error accordingly. If you're done, commit your changes to your repository, and a new build should start automatically.
