run pytest in

To run pytest in a Python project, you first need to install pytest using pip. You can do this by running the following command in your terminal:

pip install pytest

Once pytest is installed, navigate to the root directory of your Python project in the terminal and run the following command:

pytest

This will search for all files with names that match the pattern `test_*.py` or `*_test.py` in the current directory and its subdirectories, and run all tests in those files.

You can also specify a specific file or directory to run tests in by passing its path as an argument to pytest. For example:

pytest tests/test_foo.py

This will only run tests in the `test_foo.py` file located in the `tests` directory.
