Run tests in a module discovery

[brycegbrazen]

Hi all,

Looking at the "Run tests in a module" section of the docs, it doesn't mention if the path to a module must be:

• An absolute path
• A relative path
• Just a file basename that is recursively found starting with the testpaths

Can someone clarify the intended behavior? Perhaps this is something we can add explicit documentation for?

My specific issue is with bullet 3 above, where I'm trying to pass a basename to pytest via pytest basename.py, and I get a:

ERROR: file or directory not found: basename.py

It works for absolute or relative paths. If it is not working for you it must be something else, please post a full example.

My folder structure looks like:

├── src
│   ├── api
│   │   ├── checks
│   │   │   ├── maya
│   │   │   │   ├── validate_master.py
├── tests
│   ├── __init__.py
│   ├── api
│   │   ├── __init__.py
│   │   ├── checks
│   │   │   ├── __init__.py
│   │   │   ├── maya
│   │   │   │   ├── __init__.py
│   │   │   │   ├── test_validate_master.py
├── pytest.ini

The contents of my pytest.ini file look like this:

[pytest]
testpaths = tests

From the root of the folder, I want to run

pytest test_validate_master.py

where pytest can find a file with that base name under the configured test paths.
However, I get an error:

ERROR: file or directory not found: test_validate_master.py

If I give pytest a relative path from my current directory (the root folder), it does successfully find the file:

pytest tests/api/checks/maya/test_validate_master.py

...
ModuleNotFoundError: No module named 'six'

(It helps to post this as a reply to my other reply, to keep things in context)

You can run pytest tests and pytest will look for test files in that folder, passing the full path to a file also works.

ModuleNotFoundError: No module named 'six' means that six is not installed in your environment, and is not related ot pytest.

Apologies for not posting as a reply initially.

But just to clarify, is it possible to just pass a file basename if you want to run just a single file? Just curious if it will do a recursive search for the file.

No.

Not the filename directly (as @The-Compiler commented), but it is possible to use the -k flag (pytest -k basename) and pytest will collect all files and run only those that contain basename in their "node id".

[brycegbrazen]

Gotcha. Thanks for the info! One other question, is it possible to use any form of globbing (the * operator) just via the positional argument?

Something like:
pytest tests/*test_validate_master.py
or
pytest **test_validate_master.py
to search recursively?

[nicoddemus]

Not natively.

[The-Compiler]

If you're on bash, pytest **/test_validate_master.py will work - but that's a bash thing, not a pytest thing.
