Best Practices2

A testing strategy that favors many fast unit tests, fewer integration tests, and a small number of slow end-to-end tests.

A development discipline where you write a failing test first, write minimal code to pass it, then refactor, in short red-green-refactor cycles.

A test with many unlabeled assertions, so when one fails it is unclear which condition broke or why, slowing diagnosis.

Replacing nearly every collaborator with mocks so tests verify interactions instead of behavior, becoming brittle and detached from reality.
