How do I configure android tests directory?

Question

The Android gradle build forces my AndroidTests to be in src/androidTests. How do I change this to be another directory of my choosing?

Here is some background: I am migrating a project from eclipse.

According to the build documentation, when I add this to my gradle build file:

androidTest.setRoot('tests')

The android gradle build does this: "Note: setRoot() moves the whole sourceSet (and its sub folders) to a new folder. This moves src/androidTest/* to tests/*"

That is great for the build and makes it run just fine.

However, it forces my project structure to put my androidTests within: src/AndroidTest. This makes Eclipse unable to compile because it thinks all the test code should be in a package called androidTests.com.etc.etc.etc...

I'd like to set some property like this:

androidTest
{
    java.srcDirs = ['tests']
}

Answer 1

androidTest.setRoot('tests') will reset the root of the sourceSets so that

• java is under tests/java
• android res are under tests/res
• etc...

You can configure those separately though with

android {
  sourceSets {
    androidTest {
      java.srcDirs = ['tests']
    }
  }
}

Note: this uses android.sourceSets because the Android plugin uses custom sourceSets.

There are slight variations on how to do this. Putting the following in my build.gradle file worked for me:

android {
    sourceSets {
        androidTest{
            java.srcDir file('src/tests/java')
        }
    }
}
