Question about running tests

[esc]

Is it possible to run individual tests?

[mriehl]

There's a hack if you want to test just a module:

 pyb -P unittest_module_glob=reactor_tests.py

whith s/reactor_tests/your_test_module/ of course. There's no easy way to run just a test in a module right now though.

[mriehl]

Actually there is: you can override unittest_test_method_prefix with the -P switch. Same as the module example I added but with method name.

Interesting. I usually ended up with my own hack using nosetests:

PYTHONPATH=src/main/python nosetests test_module:TestClass.test_method

But this depends on correctly set PYTHONPATH. And so one thing I would really like to see is the ability to modify the environment using pybuilder to inject the PYTHONPATH, for example the way the ssh-agent does it.

eval pyb export_env

[mriehl]

Hmm.. that would definitely be really easy to add. Question is, what do you gain from it? Right now you export PYTHONPATH=src/main/python. With a task you'd still have to type eval pyb export_env which is not noticeably shorter.

I think it would be better to have an actual task that takes parameters, like
pyb run_nose "test_module:TestClass.test_method" (but we can not even parse this right now).
For this exact use case you could add a zsh function that sets both properties (module glob and method prefix).

Yeah, I'll do that. Can I get pyb to print the module and scripts path?

[mriehl]

You need to add a task for that :-/
We could consider adding these to the core python plugin since it's pretty neat for shell usage (like setting the pythonpath before starting vim, etc).

@task
def print_module_path(project):
    print(project.expand_path("$dir_source_main_python"))

@task
def print_scripts_path(project):
    print(project.expand_path("$dir_source_main_scripts"))

and then call the task with -Q (very quiet).

[esc]

Yeah, that would suffice for my use-case. Everything, else I can do by shell function. It's probably only an edge-case, since I don't know any projects that override these defaults, but just in case it would be neato and would help interoperability between pybuilder and other tools.

The original question has been answered. I'd like to close this issue and make a new one for the suggestions about the additional tasks, OK?

[mriehl]

Works for me!
