The document discusses various issues that can cause tests to run slowly such as shared fixtures, eratic tests, and dependencies between tests. It suggests techniques to avoid these problems like using fresh fixtures for each test, running subsets of tests in isolation, and designing tests to be independent from each other. The goal is to make tests run as fast as possible through these strategies.
