M220P: can't manually run projections test

MongoDB University M220P: MongoDB for Python Developers
#1

I’ve got the mflix app in a venv. In that env, I run ‘pytest -m projections’ and get:

lib/python3.9/site-packages/_pytest/config.py:366: in _importconftest
    raise ConftestImportFailure(conftestpath, sys.exc_info())
E   _pytest.config.ConftestImportFailure: ModuleNotFoundError("No module named 'requests'")
E     File "/home/pcrooker/mongo_courses/mflix/lib/python3.9/site-packages/_pytest/assertion/rewrite.py", line 212, in load_module
E       py.builtin.exec_(co, mod.__dict__)
E     File "/home/pcrooker/mongo_courses/mflix/lib/python3.9/site-packages/notebook/tests/selenium/conftest.py", line 4, in <module>
E       import requests

If I run the app itself and run the test from the Status web page it works. What is missing here? (well, the requests module, obviously) I’ve got python 3.9.7 running on Ubuntu.

thanks, Phil

Are you sure about the test name?

If I remember correction it is projection rather than projections.

Thanks, Steeve. My bad - that was a typo when creating the question. I get the error with: ‘pytest -m projection’.

#4

Post a screenshot of the whole terminal. The error message you posted is not sufficient for us to understand the context.

#5

Here tis.

If that is too small, here is (all) the text:

This

your prompt when you run the failing tests and this

(mflix) phil-envy:~/mongo_courses/mflix$

your prompt when you run the application tells me you are not setting up your virtual environment the same way when running the test as when you are running the application.

It means not the same modules are in your environment.

  • So start a new terminal as you did for running the application.
  • Change directory to the same directory you use to run the application
  • Execute the same . bin/activate command as you did when running the application
  • Your prompt should now have only (mflix) like in your last post
  • Run the test that used to failed

For some reason, I don’t even know how to do that, you reactivated the (base) virtual environment which does not have the same modules as (mflix).

#9

No, the (base) prompt is to do with anaconda, nothing to do with the python venv. I commented out the anaconda stuff that was in the .bashrc which produces the (base) prompt - it runs conda.sh. I was annoyed with the prompt.

Anyway, I just ran the projection test in the ‘new’ environment and got the same error:

Share your configuration file.

I responded via the notification email and obviously that didn’t go anywhere. What config file? I only see pyvenv.cfg:

home = /usr/bin
include-system-site-packages = true
version = 3.9.7

Looking at the error, it showed that the requests module was missing. I installed that, now I get this error:

Are you sure these test scripts actually run at the command line? Thanks.

Could I have a look at this thread?
