See the code coverage percentages for your application. For more information about local unit tests, see Building local unit tests. When you run a JUnit or instrumented test, the results appear in the Run window. A green bar means all tests succeeded and a red bar means at least one test failed. Figure 3 shows a successful test run. Figure 3. Test results appear in the Run window. The Run window displays the tests in a tree view on the left, and the results and messages for the current test suite in the output pane on the right.
Use the toolbars, context menus, and status icons to manage the test results, as follows:. If a unit test contains assertEquals failures from comparing two string objects, you can see what the differences are between the two string objects to find out what caused the failures, as follows:.
Starting in Android Studio Arctic Fox, instrumentation tests can be run across multiple devices in parallel and analyzed using the Test Matrix tool view. Using this tool view, you can more easily determine which tests are failing across various device configurations.

Test types and location The location of your test code depends on the type of test you are writing. Add a new test To create either a local unit test or an instrumented test, you can create a new test for a specific class or method by following these steps: Open the Java file containing the code you want to test.
In the menu that appears, click Create New Test. Here you can find an option called New Terminal at Folder. Click this option and select a keyboard shortcut that you want to assign. After that, open the platform-tools folder and use that keyboard shortcut to open the Terminal in that folder. The Linux users can use the same command as Mac to navigate to the corresponding folder using Terminal.
After opening the Terminal or Command Prompt in the respective folder, you need to enter this following command. Now you should find the APK file in your virtual device. If you are getting an error message, power on the virtual device and try again.

To get started building your app bundle with either approach, read Build your app from the command line. Although the Android Gradle plugin is the easiest way to build your app bundle from the command line, you should use bundletool to deploy your app from an app bundle to a connected device.
The following are the different types of scenarios you can test for using bundletool :. Whether you want to share your app with your internal stakeholders, your internal QA team, a closed group of alpha testers, or a wider audience of beta testers, the Play Console provides you with several testing strategies.
While the Play Console test tracks provide a method of progressing your app through formal testing stages, sometimes you want to quickly share your app with trusted testers over less formal channels, such as email or a text message.
By uploading your app bundle to the Play Console quick sharing page, you can generate a URL that you can easily share with others. Sharing your app this way provides these benefits:. When users click on the URL from their Android device, the device automatically opens the Google Play Store to download the test version of your app. To get started, and learn more about the capabilities and restrictions of this testing strategy, see Share your app with a URL or watch the video below.
This can be useful if, for example, you want to quickly test an earlier version of your app to check for performance regressions. Visit the Play Console app bundle explorer page and navigate to the download tab of any version you want to download to copy the install link. Alternatively, if you know the package name and version code for the version of your app you want to test, simply visit the following link from your test device:.
When you upload your app and create a release in the Play Console, you can progress your release through multiple testing stages before pushing to production:. Progressing your app through each of these testing stages allows you to open your app to wider audiences of testers before releasing your app to production. For more information on Play Console test tracks, go to Set up an open, closed, or internal test. When you upload an APK or app bundle to the open or closed track, you can identify issues for a wide range of devices running different versions of Android.
The pre-launch report on your Play Console helps you identify potential issues with the following:. After you upload your app bundle, test devices automatically launch and crawl your app for several minutes. The crawl performs basic actions every few seconds on your app, such as typing, tapping, and swiping. After tests are complete, your results will be available in the pre-launch report section of your Play Console.
To learn more, see the Play Console help topic about how to Use pre-launch reports to identify issues. To learn more, read the Play Console help topic about Reviewing your app bundle details. Firebase App Distribution makes it easy to distribute pre-release versions of your app to trusted testers so you can get valuable feedback before launch. App Distribution lets you manage all of your pre-release builds in a central hub, and it gives you the flexibility to distribute these builds right from the console or using the command-line tools that are already part of your workflow.
There are a few steps you need to take to enable your project for Firebase App Distribution. Check out the Before you begin section of the Firebase documentation.
