Dev Frontend E2E Testing (Gate 5)

Overview

Ensure all user flows from ring:product-designer have passing Playwright E2E tests across Chromium, Firefox, and WebKit with responsive viewport coverage.

Core principle: If the product-designer defined a user flow, it must have an E2E test. If the user can encounter an error, it must be tested.

<block_condition>

• Untested user flow = FAIL

• No error path tests = FAIL

• Fails on any browser = FAIL

• Flaky tests (fail on consecutive runs) = FAIL </block_condition>

CRITICAL: Role Clarification

This skill ORCHESTRATES. Frontend QA Analyst Agent (e2e mode) EXECUTES.

Who Responsibility

This Skill Gather requirements, dispatch agent, track iterations

QA Analyst Frontend Agent Write Playwright tests, run cross-browser, verify flows

Standards Reference

MANDATORY: Load testing-e2e.md standards via WebFetch.

<fetch_required> https://raw.githubusercontent.com/LerianStudio/ring/main/dev-team/docs/standards/frontend/testing-e2e.md </fetch_required>

Step 1: Validate Input

REQUIRED INPUT:

• unit_id: [task/subtask being tested]
• implementation_files: [files from Gate 0]

OPTIONAL INPUT:

• user_flows_path: [path to user-flows.md]
• backend_handoff: [endpoints, contracts from backend cycle]
• gate4_handoff: [full Gate 4 output]

if any REQUIRED input is missing: → STOP and report: "Missing required input: [field]"

if user_flows_path provided: → Load user flows as E2E test scenarios → All flows MUST be covered

if backend_handoff provided: → Verify E2E tests exercise backend endpoints → Verify request payloads match contracts

Step 2: Dispatch Frontend QA Analyst Agent (E2E Mode)

Task tool: subagent_type: "ring:qa-analyst-frontend" prompt: | MODE: E2E TESTING (Gate 5)

**Standards:** Load testing-e2e.md

**Input:**
- Unit ID: {unit_id}
- Implementation Files: {implementation_files}
- User Flows: {user_flows_path or "N/A"}
- Backend Handoff: {backend_handoff or "N/A"}

**Requirements:**
1. Create Playwright tests for all user flows
2. Test happy path + error paths (API 500, timeout, validation)
3. Run on Chromium, Firefox, WebKit
4. Test responsive viewports (mobile, tablet, desktop)
5. Use data-testid or semantic role selectors only
6. Run 3x consecutively to verify no flaky tests

**Output Sections Required:**
- ## E2E Testing Summary
- ## Flow Coverage
- ## Handoff to Next Gate

Step 3: Evaluate Results

Parse agent output:

if "Status: PASS" in output: → Gate 5 PASSED → Return success with metrics

if "Status: FAIL" in output: → If flow not covered: re-dispatch agent to add missing tests → If browser failure: re-dispatch implementation agent to fix → If flaky: re-dispatch agent to stabilize tests → Re-run E2E tests (max 3 iterations) → If still failing: ESCALATE to user

Step 4: Generate Output

E2E Testing Summary

Status: {PASS|FAIL} Flows Tested: {X/Y} Happy Path Tests: {count} Error Path Tests: {count} Browsers Passed: {X/3} Consecutive Passes: {X/3}

Severity Calibration

Severity Criteria Examples

CRITICAL User flow completely broken, data corruption Transaction fails, user data lost, checkout blocked

HIGH Missing user flow tests, flaky tests, browser failure Untested flow from product-designer, test fails intermittently

MEDIUM Error path gaps, viewport issues Missing error handling test, mobile viewport untested

LOW Selector improvements, test organization Non-semantic selectors, test file structure

Report all severities. CRITICAL = immediate fix. HIGH = fix before gate pass. MEDIUM = fix in iteration. LOW = document.

Anti-Rationalization Table

See shared-patterns/shared-anti-rationalization.md for universal anti-rationalizations. Gate-specific:

Rationalization Why It's WRONG Required Action

"Unit tests cover the flow" Unit tests don't test real browser interaction. Write E2E tests

"Only Chromium matters" Firefox and Safari have different behavior. Test all 3 browsers

"Happy path is enough" Users encounter errors. Test error handling. Add error path tests

"CSS selectors are fine" CSS changes with refactors. Use semantic selectors. Use roles and testids

"Product-designer flows are suggestions" Flows define acceptance criteria. Cover all. Test all flows

"Test is flaky, skip it" Flaky tests indicate real instability. Fix the test
