Android unit testing for audio recorder

Question

How can I write unit testing for an audio recorder module ? As per my current progress, it's only creating the file and no data is written into it since the recorder started & stopped eventually.

Answer 1

You can use Robolectric for this unit testing this. Robolectric has a shadow for MediaRecorder. For more details on this the following link will be helpful How to unit test android audio recording app using robolectric
