Trace Format

[DavertMik]

Prerequisistes:

• investigate Playwright traces first and how they work

Task

Implement AI Native trace so AI agnets could read it, and debug

Proposed format: markdown file with CodeceptJS logs and links to stored data

file: tests/user_test.js
name: <test.fullName>
time: <executionTime>
---

I.amOnPage('/app') 
  > navigated to /app page
  > [HTML](./saved-html-of-this-page)
  > HTTP [GET /users](./request-response-stored-json-file) 200
  > [ARIA](./aria representation of the page)
  > [Screenshot](./screenshot of this page)
I.click(...)
  > HTTP [POST /users](./request-response-stored-json-file) 200
  [CodeceptJS Debug output]
  > Browser Logs: ...

Error: ....

So each CodeceptJS step should also store as separate files:

• HTTP requests
• HTML of page
• ARIA snapshots
• Screenshots of page

See step-by-step reporter plugin for reference

For each test we need to create uniq folder in output/... and store all related data there

Purpose

If a test fails coding agent like Claude Code can read the failure file, extract all needed information and provide a fix.
It can also re-run the test and see if data has changed
