Event types

REGRESSION, PASS, ANOMALY, VISUAL_DIFF, HEALTH_TRANSITION.

Schema (Pydantic):

{
  "type": "REGRESSION",
  "service": "users-web",
  "file": "app/users/routes.py",
  "endpoint": "/api/users",
  "status": "fail",
  "stage": "quick",
  "reason": "TestQL exit code 1",
  "timestamp": 1730000000
}

Extra fields are preserved via model_config = {"extra": "allow"}.

Run

# Install
pip install -e wupbro/

# Dev server (auto-reload)
wupbro --reload --port 8000

# Or directly
uvicorn wupbro.main:app --host 0.0.0.0 --port 8000 --reload

Dashboard: http://localhost:8000/

OpenAPI docs: http://localhost:8000/docs

Configure WUP agent to send events

In your wup.yaml:

web:
  enabled: true
  endpoint: "http://localhost:8000"
  endpoint_env: "WUPBRO_ENDPOINT"   # fallback if endpoint is empty
  timeout_s: 2.0                     # short — must not block watcher
  api_key: ""                        # optional bearer token

Or via environment variable:

export WUPBRO_ENDPOINT=http://localhost:8000
wup watch . --mode testql

The agent will POST events fire-and-forget on:

• service health transitions (up ↔ down)
• regressions (when TestQL fails)
• visual DOM diffs (when significant changes detected)

Browserless integration

docker run -d --name browserless -p 3000:3000 browserless/chrome
export BROWSERLESS_URL=http://localhost:3000
wupbro

Then:

curl -X POST http://localhost:8000/drivers/browserless/screenshot \
  -H "Content-Type: application/json" \
  -d '{"url": "http://example.com", "full_page": true}'

Storage

Events are kept in an in-memory ring buffer (capacity 1000) and persisted to .wupbro/events.jsonl for restart durability.

Tests

PYTHONPATH=wupbro python3 -m pytest wupbro/tests/ -v

17 tests covering events router, drivers (anomaly, browserless, dom-diff, health), dashboard HTML, OpenAPI schema.
