How to Run Test Review with TEA	Audit test quality using TEA's comprehensive knowledge base and get 0-100 scoring

How to Run Test Review with TEA

Use TEA's test-review workflow to audit test quality with objective scoring and actionable feedback. TEA reviews tests against its knowledge base of best practices.

When to Use This

• Want to validate test quality objectively
• Need quality metrics for release gates
• Preparing for production deployment
• Reviewing team-written tests
• Auditing AI-generated tests
• Onboarding new team members (show good patterns)

Prerequisites

• BMad Method installed
• TEA agent available
• Tests written (to review)
• Test framework configured

Steps

1. Load TEA Agent

Start a fresh chat and load TEA:

tea

2. Run the Test Review Workflow

test-review

3. Specify Review Scope

TEA will ask what to review.

Option A: Single File

Review one test file:

tests/e2e/checkout.spec.ts

Best for:

• Reviewing specific failing tests
• Quick feedback on new tests
• Learning from specific examples

Option B: Directory

Review all tests in a directory:

tests/e2e/

Best for:

• Reviewing E2E test suite
• Comparing test quality across files
• Finding patterns of issues

Option C: Entire Suite

Review all tests:

tests/

Best for:

• Release gate quality check
• Comprehensive audit
• Establishing baseline metrics

4. Review the Quality Report

TEA generates a comprehensive quality report with scoring.

Report Structure (test-review.md):

# Test Quality Review Report

**Date:** 2026-01-13
**Scope:** tests/e2e/
**Overall Score:** 76/100

## Summary

- **Tests Reviewed:** 12
- **Passing Quality:** 9 tests (75%)
- **Needs Improvement:** 3 tests (25%)
- **Critical Issues:** 2
- **Recommendations:** 6

## Critical Issues

### 1. Hard Waits Detected

**File:** `tests/e2e/checkout.spec.ts:45`
**Issue:** Using `page.waitForTimeout(3000)`
**Impact:** Test is flaky and unnecessarily slow
**Severity:** Critical

**Current Code:**
```typescript
await page.click('button[type="submit"]');
await page.waitForTimeout(3000);  // ❌ Hard wait
await expect(page.locator('.success')).toBeVisible();

Fix:

await page.click('button[type="submit"]');
// Wait for the API response that triggers success message
await page.waitForResponse(resp =>
  resp.url().includes('/api/checkout') && resp.ok()
);
await expect(page.locator('.success')).toBeVisible();

Why This Matters:

• Hard waits are fixed timeouts that don't wait for actual conditions
• Tests fail intermittently on slower machines
• Wastes time waiting even when response is fast
• Network-first patterns are more reliable

---

2. Conditional Flow Control

File: tests/e2e/profile.spec.ts:28 Issue: Using if/else to handle optional elements Impact: Non-deterministic test behavior Severity: Critical

Current Code:

if (await page.locator('.banner').isVisible()) {
  await page.click('.dismiss');
}
// ❌ Test behavior changes based on banner presence

Fix:

// Option 1: Make banner presence deterministic
await expect(page.locator('.banner')).toBeVisible();
await page.click('.dismiss');

// Option 2: Test both scenarios separately
test('should show banner for new users', async ({ page }) => {
  // Test with banner
});

test('should not show banner for returning users', async ({ page }) => {
  // Test without banner
});

Why This Matters:

• Tests should be deterministic (same result every run)
• Conditionals hide bugs (what if banner should always show?)
• Makes debugging harder
• Violates test isolation principle

Recommendations

1. Extract Repeated Setup

File: tests/e2e/profile.spec.ts Issue: Login code duplicated in every test Severity: Medium Impact: Maintenance burden, test verbosity

Current:

test('test 1', async ({ page }) => {
  await page.goto('/login');
  await page.fill('[name="email"]', 'test@example.com');
  await page.fill('[name="password"]', 'password');
  await page.click('button[type="submit"]');
  // Test logic...
});

test('test 2', async ({ page }) => {
  // Same login code repeated
});

Fix (Vanilla Playwright):

// Create fixture in tests/support/fixtures/auth.ts
import { test as base, Page } from '@playwright/test';

export const test = base.extend<{ authenticatedPage: Page }>({
  authenticatedPage: async ({ page }, use) => {
    await page.goto('/login');
    await page.getByLabel('Email').fill('test@example.com');
    await page.getByLabel('Password').fill('password');
    await page.getByRole('button', { name: 'Sign in' }).click();
    await page.waitForURL(/\/dashboard/);
    await use(page);
  }
});

// Use in tests
test('test 1', async ({ authenticatedPage }) => {
  // Already logged in
});

Better (With Playwright Utils):

// Use built-in auth-session fixture
import { test as base } from '@playwright/test';
import { createAuthFixtures } from '@seontechnologies/playwright-utils/auth-session';

export const test = base.extend(createAuthFixtures());

// Use in tests - even simpler
test('test 1', async ({ page, authToken }) => {
  // authToken already available (persisted, reused)
  await page.goto('/dashboard');
  // Already authenticated via authToken
});

Playwright Utils Benefits:

• Token persisted to disk (faster subsequent runs)
• Multi-user support out of the box
• Automatic token renewal if expired
• No manual login flow needed

---

2. Add Network Assertions

File: tests/e2e/api-calls.spec.ts Issue: No verification of API responses Severity: Low Impact: Tests don't catch API errors

Current:

await page.click('button[name="save"]');
await expect(page.locator('.success')).toBeVisible();
// ❌ What if API returned 500 but UI shows cached success?

Enhancement:

const responsePromise = page.waitForResponse(
  resp => resp.url().includes('/api/profile') && resp.status() === 200
);
await page.click('button[name="save"]');
const response = await responsePromise;

// Verify API response
const data = await response.json();
expect(data.success).toBe(true);

// Verify UI
await expect(page.locator('.success')).toBeVisible();

---

3. Improve Test Names

File: tests/e2e/checkout.spec.ts Issue: Vague test names Severity: Low Impact: Hard to understand test purpose

Current:

test('should work', async ({ page }) => { });
test('test checkout', async ({ page }) => { });

Better:

test('should complete checkout with valid credit card', async ({ page }) => { });
test('should show validation error for expired card', async ({ page }) => { });

## Tips

### Review Before Release

Make test review part of release checklist:

```markdown
## Release Checklist
- [ ] All tests passing
- [ ] Test review score > 80
- [ ] Critical issues resolved
- [ ] Performance within budget

Review After AI Generation

Always review AI-generated tests:

1. Run atdd or automate
2. Run test-review on generated tests
3. Fix critical issues
4. Commit tests

Set Quality Gates

Use scores as quality gates:

# .github/workflows/test.yml
- name: Review test quality
  run: |
    # Run test review
    # Parse score from report
    if [ $SCORE -lt 80 ]; then
      echo "Test quality below threshold"
      exit 1
    fi

Review Regularly

Schedule periodic reviews:

• Per story: Optional (spot check new tests)
• Per epic: Recommended (ensure consistency)
• Per release: Recommended for quality gates (required if using formal gate process)
• Quarterly: Audit entire suite

Focus Reviews

For large suites, review incrementally:

Week 1: Review E2E tests Week 2: Review API tests Week 3: Review component tests (Cypress CT or Vitest) Week 4: Apply fixes across all suites

Component Testing Note: TEA reviews component tests using framework-specific knowledge:

• Cypress: Reviews Cypress Component Testing specs (*.cy.tsx)
• Playwright: Reviews Vitest component tests (*.test.tsx)

Use Reviews for Learning

Share reports with team:

Team Meeting:
- Review test-review.md
- Discuss critical issues
- Agree on patterns
- Update team guidelines

Common Issues

Low Determinism Score

Symptoms:

• Tests fail randomly
• "Works on my machine"
• CI failures that don't reproduce locally

Common Causes:

• Hard waits (waitForTimeout)
• Conditional flow control (if/else)
• Try-catch for flow control
• Missing network-first patterns

Fix: Review determinism section, apply network-first patterns

Low Performance Score

Symptoms:

• Tests take > 1.5 minutes each
• Test suite takes hours
• CI times out

Common Causes:

• Unnecessary waits (hard timeouts)
• Inefficient selectors (XPath, complex CSS)
• Not using parallelization
• Heavy setup in every test

Fix: Optimize waits, improve selectors, use fixtures

Low Isolation Score

Symptoms:

• Tests fail when run in different order
• Tests fail in parallel
• Test data conflicts

Common Causes:

• Shared global state
• Tests don't clean up
• Hard-coded test data
• Database not reset between tests

Fix: Use fixtures, clean up in afterEach, use unique test data

"Too Many Issues to Fix"

Problem: Report shows 50+ issues, overwhelming.

Solution: Prioritize:

1. Fix all critical issues first
2. Apply top 3 recommendations
3. Re-run review
4. Iterate

Don't try to fix everything at once.

Reviews Take Too Long

Problem: Reviewing entire suite takes hours.

Solution: Review incrementally:

• Review new tests in PR review
• Schedule directory reviews weekly
• Full suite review quarterly
