Android test raw resource

I have the following folder structure in Android Studio:

├── androidTest
│   ├── java
│   └── res
│   └── raw
│   └── test_file
└── main
├── java
└── res
└── raw
   └── app_file


I'm trying to access the
test_file
resource which exists in the raw folder of the androidTest elements. Here's the code inside a Robotium test case that inherits from
ActivityInstrumentationTestCase2
:

InputStream is = this.getInstrumentation()
.getContext()
.getResources()
.openRawResource(R.raw.test_file);


Android Studio throws a reference error since the resource cannot be found. The exact error is "Cannot resolve symbol test_file".

How can I reference this resource form a test case, which exists on the androidTest resources bundle?

Answer

By default your androidTest project will include your app's R class, but androidTest's resources will be generated into a separate file. Make sure you import the R class from your test project:

import com.your.package.test.R;

[..]

getInstrumentation().getContext().getResources().openRawResource(R.raw.test_file);

You can also directly reference the test project's R class:

getInstrumentation().getContext().getResources().openRawResource(com.your.package.test.R.raw.test_file);
