E2E SKILL
Config loading
Read .claude/maestro.json to resolve project-specific values:
{TEMP_ROOT}=.ai.temp_root{REPO}=.ai.repo{SLUG}=.ai.slug{E2E_URL}=.ai.e2e.local_url{E2E_BOOT}=.ai.e2e.boot_cmd{E2E_SETTINGS}=.ai.e2e.settings_path{E2E_CI}=.ai.e2e.ci_integration
This skill provides end-to-end test execution at two tiers. The tooling is the same (Playwright MCP + curl + WP-CLI); the difference is scope and depth.
The local WordPress environment is at {E2E_URL} (admin / password). Boot
or restart it with {E2E_BOOT}.
Tier 1 — Basic
Purpose: behavioral verification and smoke tests. Fast enough to fit inside a planning agent's execution window.
Invokers:
grooming-agent— verify behavioral assumptions about the current system before writing the spec. Use to confirm: does the current feature behave as described in the issue? What does the current API or AJAX endpoint return for the scenario being changed?
Anti-rationalization table
| You'll be tempted to say | Why you can't |
|---|---|
| "The environment probably isn't up, I'll skip" | Run {E2E_BOOT}. It's idempotent. If it fails, log SKIP with the reason — do not silently omit the step. |
| "The change is backend-only, no need to smoke it" | The primary happy path must be verified. A backend change with no observable behavior change still needs a confirming assertion. |
| "I already read the code, I know it works" | "Seems right" never closes a task. Run the scenario. |
| "One scenario is too slow for this stage" | Basic tier is exactly one primary scenario. The cost is acceptable. |
Basic tier process
Boot the environment (idempotent — safe to run if already up):
{E2E_BOOT}If the script exits non-zero, set
status: "SKIP", note the reason, and do not block the pipeline.Run the primary happy path scenario from the spec or grooming plan.
Backend / AJAX / REST:
# Public REST or AJAX curl -s -X POST {E2E_URL}/wp-admin/admin-ajax.php \ -H "Cookie: $(cat .wp-session-cookie 2>/dev/null)" \ -d 'action=<action>&nonce=...' # Cache headers curl -sI {E2E_URL}/ | grep -E '(x-cache|cf-cache)' # WP-CLI inside the dev environment bin/wp <command>Browser (settings page, dashboard notices, interactive UI): Use the Playwright MCP directly for basic-tier smoke. Do not delegate to
e2e-qa-testerat this tier (that is the extended tier path):mcp__playwright__navigate({ url: "{E2E_URL}/wp-login.php" }) # login mcp__playwright__fill({ selector: "#user_login", value: "admin" }) mcp__playwright__fill({ selector: "#user_pass", value: "password" }) mcp__playwright__click({ selector: "#wp-submit" }) # primary scenario mcp__playwright__navigate({ url: "{E2E_SETTINGS}" }) mcp__playwright__snapshot({}) # Inspect snapshot output to confirm expected element/text is presentTake at most 1–2 screenshots if helpful, but do not publish them at this tier.
Report:
{ "status": "PASS|FAIL|SKIP", "scenarios_tested": ["Settings page loads without errors after enabling X option"], "details": "Logged in as admin, navigated to {E2E_SETTINGS}, confirmed no JS console errors and X toggle present" }SKIP:{E2E_BOOT}failed or environment unreachable. Record reason. Do not block the pipeline.
Basic tier boundaries
- ✅ Do: verify the one primary scenario from the spec or grooming plan
- ✅ Do: probe current-system behavior (grooming-agent only) when an assumption needs verification
- 🚫 Do not: cover all acceptance criteria (that is extended tier)
- 🚫 Do not: write or commit Playwright specs (that is extended tier via
e2e-qa-tester) - 🚫 Do not: publish screenshots (that is extended tier)
Tier 2 — Extended
Purpose: full acceptance criteria coverage, regression testing, edge cases, visual comparison, and Playwright spec authoring with screenshot evidence.
Invoker: qa-engineer only.
Execution: the qa-engineer agent delegates browser flows to the e2e-qa-tester
sub-agent, which handles Playwright MCP driving, temporary spec authoring under
.e2e-temp/, screenshot publishing via the commit-SHA method, and clean-up.
The qa-engineer agent itself handles:
- Strategy A (API / functional validation via curl and WP-CLI)
- Strategy C (test-suite-only fallback when the environment is unreachable)
For details, read:
.claude/agents/qa-engineer.md— strategy selection and report format.claude/agents/e2e-qa-tester.md— browser flow execution, spec authoring, screenshot publishing
The extended tier writes Playwright specs to .e2e-temp/ (gitignored, never committed when {E2E_CI} is false)
and screenshots to .e2e-screenshots/. Screenshots are published to a public GitHub Gist (gh gist create --public) to get permanent, publicly accessible raw URLs — no commits to the PR branch. Gist raw URLs never 404 in PR comments, unlike commit-SHA-based URLs.
When to use which tier
| Invoker | Tier | Purpose |
|---|---|---|
grooming-agent |
Basic | Verify a behavioral assumption before writing the spec |
qa-engineer |
Extended | Full acceptance criteria + regression + screenshots |
Project-specific notes
- The boot script
{E2E_BOOT}is idempotent. Always run it before testing — don't pre-check whether the environment is up. - Admin credentials:
admin/password. - Settings page URL:
{E2E_SETTINGS}. - Plugin activation check (no login needed):
curl -s -o /dev/null -w "%{http_code}" {E2E_SETTINGS} - For cache-header tests, send a request to a front-end URL and inspect the project's cache response headers.
- The basic tier never writes Playwright spec files and is invoked by grooming-agent only. Implementation agents (backend-agent, frontend-agent) do not invoke the e2e skill — full E2E validation belongs to the qa-engineer + e2e-qa-tester tier.
- If
{E2E_CI}is true, the project maintains a permanent E2E suite —e2e-qa-testerwill commit spec files rather than delete them.
