I want to write some tests for a python MFCC feature extractor for running

  • 0

I want to write some tests for a python MFCC feature extractor for running with nosetest. As well as some lower-level tests, I would also like to be able to store some standard input and expected-output files with the unit tests.

At the moment we are hard-coding the paths to the files on our servers, but I would prefer the testing files (both input and expected-output) to be somewhere in the code repository so they can be kept under source control alongside the testing code.

The problem I am having is that I’m not sure where the best place to put the testing files would be, and how to know what that path is when nosetest calls each testing function. At the moment I am thinking of storing the testing data in the same folder as the tests and using __file__ to work out where that is (would that work?), but I am open to other suggestions.

    I think that using __file__ to figure out where the test is located and storing data alongside the it is a good idea. I’m doing the same for some tests that I write.

    This:

    os.path.dirname(os.path.abspath(__file__))

    is probably the best you are going to get, and that’s not bad. 🙂
