Playwright-based E2E tests that drive the MCP Inspector UI through the full OAuth flow against the real Forms worker (src/worker.ts), which includes both Forms tool collections and in-process CMS chaining.
Key files:
- Test file:
tests/forms-hosted-e2e/e2e/mcp-inspector.test.ts - Worker setup:
tests/forms-hosted-e2e/e2e/helpers/worker-setup.ts - Wrangler config:
tests/forms-hosted-e2e/wrangler.e2e.toml - Shared test helpers from
@umbraco-cms/mcp-hosted/testing
Steps
1. Check prerequisites
- Verify
demo-site/exists (has a.csprojfile). If not, tell the user to runnpx create-umbraco-mcp-server init.
2. Kill stale processes
Kill any stale processes on the E2E ports (Umbraco, Worker, Inspector):
npm run kill:e2e-ports
Tell the user which stale processes were found and killed.
3. Build the project
Build the worker before running tests:
npm run build
4. Start Umbraco as a background subprocess
Start Umbraco using the existing npm script with run_in_background: true:
npm run start:umbraco
Then wait for Umbraco to be ready. Run this single bash command which loops until the health check succeeds (up to 120 seconds):
for i in $(seq 1 24); do if curl -sk -o /dev/null -w '%{http_code}' https://localhost:44374 --max-time 5 | grep -q '200\|302'; then echo "Umbraco is ready"; exit 0; fi; echo "Waiting for Umbraco... (attempt $i/24)"; sleep 5; done; echo "Umbraco failed to start within 120s"; exit 1
Tell the user you're waiting for Umbraco to start. If the health check fails after 120 seconds, tell the user and stop.
5. Run the E2E tests
The Cloudflare Worker and MCP Inspector are started automatically by the test framework (via worker-setup.ts and shared helpers) — no manual setup needed.
Run the tests:
npm run test:e2e
If the user asked for a specific test, use:
npx playwright test --config tests/forms-hosted-e2e/e2e/playwright.config.ts -g "<test-name>"
Useful flags the user may request:
--headed— watch tests in browser--debug— open Playwright InspectorSLOW_MO=500— slow down browser actions
6. Report results
Show the test results to the user. If tests failed, read the relevant test file and any error output to help diagnose.
7. Cleanup
Do NOT stop the Umbraco instance after tests — the user may want to run them again or use it for other work. Only stop it if the user explicitly asks.
Prerequisites reference
These must be set up once (not part of the skill flow):

demo-site/directory - Umbraco backoffice user with credentials:
admin@test.com/SecurePass1234 - OAuth client
umbraco-mcp-forms-hostedregistered in the Umbraco backoffice - Playwright browsers:
npx playwright install
