How can one write an Integration Test that requires an Android Context?

Question

For example, testing input/output to an image file. To create the file, the following code is used (summary):

 File storageDir = getExternalFilesDir(Environment.DIRECTORY_PICTURES);
 File image = File.createTempFile("tempImage",".jpg",storageDir);
 mCurrentPhotoPath = image.getAbsolutePath();
 mCurrentPhotoURI = FileProvider.getUriForFile(this,"com.example.android.fileprovider",image);
 File photoFile = image;

When I try to write an integration test using this code to create a file, I have issues with the getExternalFilesDir and this (which is a context). How can I effectively test without having an activity or context to pass? Can I generate one?

Are you using Mockito? http://stackoverflow.com/questions/34063848/how-to-mock-context-using-mockito — OneCricketeer, Dec 19 '16 at 22:19
That's an IDE. You can test your app using Mockito - that was my question - what testing framework do you have? — OneCricketeer, Dec 19 '16 at 22:22
No testing framework - do you have a summary of how that integrates/works? Or should I just google it and do some research? — Evan Weissburg, Dec 19 '16 at 22:23
Mock testing is different than integration testing, so I'm probably leading you on the wrong path, anyway — OneCricketeer, Dec 19 '16 at 22:24

In an instrumentation test, InstrumentationRegistry.getTargetContext() returns a Context for the package being tested.
