Generic Dynamic Journey Builder

Turns a Chrome DevTools HAR export into a repeatable API test — it pulls out values, chains the requests and checks the results.

The problem

Recording a user journey in the browser is easy. Turning it into an automated API test by hand is slow.

How it works

  1. 01Import HAR
  2. 02Find values
  3. 03Chain requests
  4. 04Replay
  5. 05Assert

What was hard

  • The same ID can appear in many places, so each extracted value has to be mapped to the right later request.
  • HAR files can hold passwords and tokens, which must be stripped before anything is saved.
  • Values from one response feed the next request, so the chain order matters.

The result

A recorded browser session becomes a repeatable, automated API test.
