Test Runner

Definitions

1. A program that discovers test files, executes them in a controlled environment, captures pass/fail results, and reports outcomes — examples include Jest, pytest, and go test.

   In plain English: The program that actually finds and runs your tests and tells you which ones passed or failed.

   Example: "The test runner found 847 tests, ran them in parallel across 4 workers, and finished in under a minute."
