Using assets in robolectric tests

I was able to make it like this:

1) Copy (or create) AndroidManifest.xml in test folder

2) Add @Config(emulateSdk = 18, manifest = "src/test/AndroidManifest.xml") for this specific test

I was able to read file. So it means you could play with AndroidManifest class and custom runner (more inspiration here https://groups.google.com/forum/#!topic/robolectric/YvbdqRFcdnA)

I think it could be also possible to play with build.gradle:

android {
  sourceSets {
    androidTest.setRoot( 'src/test' )

    androidTest {
      assets.srcDir file( 'src/test/assets' )
    }
  }
}

but I'm not sure since plugin doesn't create any build variant but just tasks.

Since my tests are just reading these files and returning file data as a String I was able to do that via getClass().getClassLoader().getResourceAsStream(MY_FILE_PATH) and then read file. Dont really need to read to use getShadowApplication().getAssets().open(MY_FILE_PATH).

I just moved my test data files to src/test/resources and it worked. :)
