Testing only the methods that you want

Currently if I call run the test_person.py file, each test is run sequentially. So, if I am looking only to run the newest test, I am having to wait until all the above tests are first completed. Is there any way to run only the test I want to run?

You specify individual tests to run with python -m unittest A.B.C.D where

• A - the test directory
• B - the test module (python file name without .py)
• C - the test class
• D - the method in the class you want to run

Also, you should put your tests in a test directory rather than src.

Thanks Nick! My file structure is above. When I call the test as you suggested, I get an error that says:

    module = __import__(module_name)
  File "/Volumes/GoogleDrive/My Drive/code/cadre/python/test/test_person.py", line 4, in <module>
    from src import cadre_model
  File "/Volumes/GoogleDrive/My Drive/code/cadre/python/src/cadre_model.py", line 8, in <module>
    import cadre_person
ModuleNotFoundError: No module named 'cadre_person

I suspect it is because I am not correctly importing the module files in the test module? I have

from src import cadre_model
from src import cadre_person

Am I doing this wrong?

The command I am calling is

python -m unittest test.test_person.TestPerson.test_age_assignment

from root.

Just noticed your project structure is a bit off. The src directory should be your package name. Something like cadre or whatever you want to call it. So, the imports would be from cadre import cadre_model etc.

To make the tests work, you may need to add something like:

try:
    from cadre import cadre_model
except ModuleNotFoundError:
    sys.path.append("{}/...".format(os.path.dirname(os.path.abspath(__file__))))
     from cadre import cadre_model

But I don't think that should be necessary if you are running the tests from the parent directory of the tests directory.

Oh, you might need a init.py in the tests directory.

Thanks Nick! I do have an _init_ in the test directory, though I have some stuff that was automatically generated as well. Is the generated stuff possibly causing issues? And I should rename src to cadre? And then in the test_person.py file add from cadre import cadre_model and from cadre import cadre_person?

I think I got this to work. The error was that once my code is organized into modules, I needed to update the import statement headers in the other files as well. That's it - it works now. thanks @ncollier
