You can use -k option to run test cases with different patterns:
py.test tests_directory/foo.py tests_directory/bar.py -k 'test_001 or test_some_other_test'
This will run test cases with name test_001 and test_some_other_test deselecting the rest of the test cases.
Answer from supamaze on Stack OverflowNote: This will select any test case starting with test_001 or test_some_other_test. For example, if you have test case test_0012 it will also be selected.

Specifying tests / selecting tests
Pytest supports several ways to run and select tests from the command-line.
Run tests in a module
pytest test_mod.py
Run tests in a directory
pytest testing/
Run tests by keyword expressions
pytest -k "MyClass and not method"
This will run tests which contain names that match the given string expression, which can include Python operators that use filenames, class names and function names as variables. The example above will run TestMyClass.test_something but not TestMyClass.test_method_simple.
Run tests by node ids
Each collected test is assigned a unique nodeid which consist of the module filename followed by specifiers like class names, function names and parameters from parametrization, separated by :: characters.
To run a specific test within a module:
pytest test_mod.py::test_func
Another example specifying a test method in the command line:
pytest test_mod.py::TestClass::test_method
Run tests by marker expressions
pytest -m slow
Will run all tests which are decorated with the @pytest.mark.slow decorator.
For more information see marks.
Run tests from packages
pytest --pyargs pkg.testing
This will import pkg.testing and use its filesystem location to find and run tests from.

Here’s an advanced example, which also uses monkeypatch, which is a great way for making things hard to split into units into unit tests. Let’s say you wanted to make a test that “tricked” your code into thinking that it was running on different platforms: import platform import pytest @pytest.fixture(params=["Linux", "Darwin", "Windows"], autouse=True) def platform_system(request, monkeypatch): monkeypatch.setattr(platform, "system", lambda _: request.param)

Suppose, we want to run only a specific set of tests; how do we go about it? Pytest provides two ways to run the subset of the test suite. Select tests to run based on substring matching of test names. Select tests groups to run based on the markers applied. We will explain these two with examples in subsequent chapters.
