easily run python unit tests

Project description

So here was my problem, I would work on big Python projects, and I would be adding a new python file to a module in this big project, for example, my new file might be something like this:


I would be adding the Happy class with a sad method to newmodule and I would want to test it, so I would then have to add a test for it:


Then I would want to test my new class method:

$ python -m unittest

This got really annoying! Everytime, I would have to remember the syntax to call unittest from the command line, and then I would have to remember what I named the test case (let’s see, was that HappyTestCase or HappyTest), so I decided to take a bit of time and simplify it, that’s when pyt was born.

With pyt, I just need to remember what I’m working on:

$ pyt Happy.sad

and pyt will do the rest, it will check every test module it finds in the working directory and see if it has a Happy test case with a test_sad method. No more having to remember the unittest syntax, no more typing long test paths. Hopefully, if tests are easy to run, I’ll write more of them.

More examples

Continuing the above example

To run all the Happy tests:

$ pyt Happy

To run all the newmodule tests:

$ pyt newmodule

To run more than one test:

$ pyt test1 test2 ...

Things to be aware of

  • pyt uses Python’s PEP 8 style conventions to decide what is the module and class, so, given input like this:

    $ pyt

    pyt will consider to be modules, Baz to be a class because it starts with a capital letter, and che to be a method since it comes after a class.

  • pyt can fail on vague input and will run the first satisfactory test it finds, so if you have:


    and you want to run tests for foo.user and you run:

    $ pyt user

    it will run the first user_test it finds, even if you meant a different one, the solution is to just be more verbose when you have to be:

    $ pyt foo.user


Use pip:

$ pip install git+
