How do I add unit or integration tests to and existing Android Studio project?

I've tried adding folders in Project View as well as creating tests through the context menu (right-click).

I can't get Android Studio to recognize the folder as test folders.

I've also tried:

  • How to get Android Studio to recognize file as source (test)
  • Unit testing in android studio
  • Create unit tests in android studio

Adding a test directory labeled 'androidTest' is only recognized as a test directory if you already have directory 'test' under your src/ directory.

This is as of Android 3.1.3.

Adding unit tests to existing Android Studio project, Adding a test directory labeled 'androidTest' is only recognized as a test directory if you already have directory 'test' under your src/ directory. Running simple JUnit tests on Android Studio (IntelliJ) when using a Gradle-based configuration. I am using Android Studio/IntelliJ to build on an existing Android project and would like to add some simple JUnit unit tests.

I can't get Android Studio to recognize the folder as test folders.

Following below folder structure, you should be able to see all your test cases labeled as "test" when select your Project View as "Android"

|- src
  \-- androidTest // for android instrumentation tests
  \-- main        // your source code
  \-- test        // for unit tests

Build local unit tests, Adding pure Java unit tests to an Android project are not familiar with gradle; are not familiar with android in writing "pure" unit tests for Android; are working with an existing Android project that succesfully builds and runs. Setup a Android-Test for your test class . Select your Android test configuration on the left side or create a new one with the plus icon and name it e.g. ClassNameTest. Select the module containing your test class. In the simplest case the test class is in your app module so select app. Select on the next row your test configuration. I use:

I had a similar issue, my Android TV had no 'androidTest' nor 'Test' directories, and I wanted to add some unit tests to the project.

What I did was to create an new Android project from scratch (regular app, not for TV), and I copied the test directory from the new project into my existing project (mantaining the folder structure that @shizhen mentioned above).

Finally I renamed the package folder's names and I got the ExampleUnitTest to run and work ok. After that, I could begin writing unit tests on my Android TV project.

Hope it Helps! It's probably not the best solution, but it works

Developing Android unit and instrumentation tests - Tutorial, Here I'm talking about tests that needs Emulator or a device to run, not pure java unit test. For example for testing a provider. The test example  Unit tests run on a local JVM on your development machine. Our gradle plugin will compile source code found in src/test/java and execute it using the usual Gradle testing mechanisms. At runtime, tests will be executed against a modified version of android.jar where all final modifiers have been stripped off. This lets you use popular mocking libraries, like Mockito.

Adding pure Java unit tests to an Android project, Two basic forms of testing Android Studio supports are local unit tests and instrumented tests. By creating and running unit tests against your code, you can verify that the logic of individual functional code To prepare your project for testing in Android Studio, you need to: The existing unit test class files are shown. The recent versions of Android Studio has added a test folder to its default project template. In case you are using a template which does not create a test folder, you have to create it manually. To create the test folder in Android Studio, switch to the Project view, this shows you the directory structure of your project.

By creating and running unit tests against your code, you can easily verify that the logic of individual units is correct. Running unit tests after every build helps you to quickly catch and fix software regressions introduced by code changes to your app.
