@Retention(value=CLASS)
 @Target(value=TYPE)
public @interface TestInstallIn

The annotated class must also be annotated with Module.

Example:

   // Replaces FooModule with FakeFooModule, and installs it into the same component as FooModule.
    @Module
    @TestInstallIn(components = SingletonComponent.class, replaces = FooModule.class)
   public final class FakeFooModule {
      @Provides
     static Foo provideFoo() {
       return new FakeFoo();
     }
   }
