"Run test under cursor" fails with python error

[chetan51]

When I use the "Run test under cursor" feature, I see the following error in my Sublime Text console:

Traceback (most recent call last):
  File "/Applications/Sublime Text.app/Contents/MacOS/sublime_plugin.py", line 549, in run_

What do you have under the cursor when you use the feature?

[chetan51]

I tried putting the cursor on the following lines:

https://github.com/numenta/nupic/blob/master/tests/unit/py2/nupic/research/temporal_memory_test.py#L41 https://github.com/numenta/nupic/blob/master/tests/unit/py2/nupic/research/temporal_memory_test.py#L47

Well, as you can see here, this project seems to be really complex, make sure that you can run the tests following their instructions there and if you are able to pass the tests then you should configure the anaconda's test runner in order to run the tests in that project cos they aren't going to work out of the box.

Take a look at the anaconda's test runner documentation for more information

Installing nupic in a virtual environment and following the procedure below I managed to run the whole test suite (I am not familiar with pytest so I am not sure how the configuration to make test under the cursor be fired will be, but I am pretty sure that it can be configured)

I cloned numpic in my /tmp directory.

mkvirtualenv borrame
cd /tmp/numpic
pip install -r external/common/requirements.txt
python setup.py build
python setup.py develop 

Then I saved a project file for numpic and configured it as:

"settings":
    {
        "python_interpreter": "/home/damnwidget/.virtualenvs/borrame/bin/python",
        "test_command": "python /tmp/nupic/scripts/run_tests.py -u",
        "test_before_command": "export NUPIC=/tmp/nupic",
        "test_virtualenv": "~/.virtualenvs/borrame"
    }

Then when I run, Run full project test suite It just get tested:

Thanks for putting in the effort! I was already able to run all the tests in the project, but I wasn't able to run an individual test using anaconda. Were you able to use the "Run test under cursor" on an individual unit test in the project?

[DamnWidget]

Nope, I have no idea how to run individual tests using pytest, I just managed to run tests on current file using "test_command": "python -m unittest",

[chetan51]

What does anaconda's feature "Run test under cursor" do in order to run an individual test? I am trying to make that work with the nupic project.

Hi @chetan51

I am going to sleep now (almost 03:00 AM here in Dublin) but you can take a look at here and here

[chetan51]

Thanks. I'm curious, if you run the same unit test using the "Run test under cursor feature" that I pointed out in my original description, in your cloned nupic repo, what do you see? Do you see the error I mentioned?

[DamnWidget]

Yes.

[DamnWidget]

I'll take a look on that this weekend but fixes wouldn't be available until 1.3.5

[chetan51]

Thanks so much!

[DamnWidget]

This error has been fixed in branch fix238, waiting for release v1.3.6

[chetan51]

Thanks!
