Run all unit tests in Android Studio

1. In "Project" panel (CMD+1 to show) Right click on "java".
2. Click "Run tests in Java

With AndroidStudio ArcticFox the approach is as follows:

In the toolbar under the run configuration select "Edit Configurations"

Select (+) to add a new configuration and choose Gradle:

On the configuration page:

• give the configuration a Name (Run all unit tests)
• Choose your root project as Gradle Project
• add the Tasks cleanTestDebugUnitTest testDebugUnitTest (you can copy that from an existing configuration for unit tests, but make sure to remove the module prefix (e.g. :app:))
• add --tests "*" as Arguments (apparently that tells AS to show the results as TestResults)

Select and run your new configuration. The Results will be shown in the run window:

First, you can list all the test tasks available in your project with

./gradlew tasks

Then you can choose the tasks you want to execute. If you want to execute all tests for all flavors ans all buildTypes, you just have to run

./gradlew test connectedAndroidTest

If you don't want to remember all the gradle test command each time you want to run the tests, you can create a file "custom_tasks.gradle" and add

task testAll(dependsOn: ['test', 'connectedAndroidTest']) {
   group = 'custom_tasks'
   description = "Run all tests"
}

Then, you just have to run

./gradlew testAll

Not sure what version of Android Studio this was added in, but I'm using Android Studio 3.4.

In the Project Explorer Window, select the Project View.

Right click on your root project and select "Create 'All Tests'..."

...this window will appear (these defaults need to be changed)

Change the following options:

• Search for tests:

  • In whole project

• JRE:

  • Most recent version of Android API __ Platform that you have available in this menu (for me, Android API 28 Platform

• Click Apply

• Select "All Tests" from the drop down menu

• View output from all your tests
