🔴 YOU WRITE THE TEST FIRST.

Changed code → run the tests. New feature → write the test before the code. The test is the spec. The test is done when it's green. No test = not done.

API Testing with HelpMeTest

The API library runs HTTP requests inside the active browser tab. This means the browser's session cookies, auth headers, and credentials are sent automatically — no token juggling.

A live httpbin instance is available for examples and exploration: https://httpbin.playground.helpmetest.com

The Golden Rule

Authenticate with As <StateName> FIRST, then make API calls. The browser session carries everything.
