How can I customize pytest for my testing needs?

You can customize pytest by using configuration files, plugins, and command-line options. What specific customization are you looking for?

I want to change the default test discovery pattern.

You can do this by creating a pytest.ini file and adding a testpaths option. For example:

[pytest]
testpaths = my_tests

Can I create custom markers for my tests?

Yes, you can create custom markers in your pytest.ini file. Just add a markers section like this:

[pytest]
markers =
    slow: mark test as slow
    fast: mark test as fast

How do I use these markers in my tests?

You can use the markers by adding them as decorators to your test functions. For example:

@pytest.mark.slow
def test_slow_function():
    pass
