How can I improve the performance of my pytest tests?

There are several strategies you can use to improve pytest performance, such as using fixtures efficiently, running tests in parallel, and optimizing your test code.

What are some specific ways to run tests in parallel?

You can use the pytest-xdist plugin to run tests in parallel. Install it with pip install pytest-xdist and then run your tests with the -n option followed by the number of CPU cores you want to use.

Are there any best practices for writing efficient test cases?

Yes, some best practices include minimizing the use of global state, avoiding unnecessary I/O operations, and keeping your tests independent from each other.

How can I measure the performance of my tests?

You can use the pytest-benchmark plugin to measure the performance of your tests. It provides detailed reports on execution time and allows you to compare different test runs.
