Documentation

README

Excerpt

Understand the requirement — what specific behavior must exist?
Write one test asserting that behavior
Run the test — it MUST fail (red)
Verify the failure reason — not a syntax error, but a missing implementation

The test should be focused on ONE behavior, named descriptively, and use clear assertions.

This is the opening of the README. Read the full README on GitHub.
