In a real scenario, we will have multiple test files and each file will have a number of tests. Tests will cover various modules and functionalities. 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.
