Connect and share knowledge within a single location that is structured and easy to search. The same logic applies to the conftest.py file: it will be imported as foo.conftest module. Note that on Windows the slashes in the path lean forward, like so /. Specifies whether to enable or disable auto run test discovery when saving a test file. You might occasionally need to step through and analyze tests in the debugger, either because the tests themselves have a code defect you need to track down or in order to better understand why an area of code being tested is failing. This is a perfect example of that. equivalent behaviour, except that the latter will add the current directory to sys.path, which If both frameworks are enabled, then the Python extension will only run pytest. The extention works like a charm. package under test has the same import root. Should we burninate the [variations] tag?

If VS Code is using the environment variable 'pythonpath', you should be able to add the path to your own module so that VS Code knows where to look for stuff to import. Because the test failure can easily be traced to a particular code change, it's easy to find and remedy the cause of the failure, which is undoubtedly better than discovering a problem much later in the process! Use a full path if pytest is located outside the current environment. The equivalent setting for unittest should be disabled. How can i extract files in the directory where they're located with the find command? Asking for help, clarification, or responding to other answers.

It's especially important to test security cases like injection attacks if the validated string is later used in database queries or displayed in the app's UI. If you have the pytest-cov coverage module installed, VS Code doesn't stop at breakpoints while debugging because pytest-cov is using the same technique to access the source code being run. Stack Overflow for Teams is moving to its own domain! Add new line in .env file (/home/singleheart/mywork is the location of my workspace) If VS Code is using the environment variable 'pythonpath', you should be able to add the path to your own module so that VS Code knows where to look for stuff to import.
