This article examines the testing landscape—unit tests, integration tests, end-to-end tests, the test pyramid, and test double patterns—providing practical guidance for building effective test suites. The Test Pyramid The test pyramid, popularized by Mike Cohn, describes the ideal distribution of tests. At the base are unit tests—fast, numerous, and focused on small units of code. In the middle are integration tests that verify interactions between components. At the top are end-to-end tests that validate complete user workflows. The pyramid shape is intentional.…
