Phase 1: Test Strategy

Strategy Brief

Before writing any tests, define the strategy:

# test-strategy.yaml
project: "[name]"
scope: "[feature/module/full product]"
risk_level: high | medium | low
stack:
  language: "[TypeScript/Python/Java/Go]"
  framework: "[React/Express/Django/Spring]"
  test_runner: "[Jest/Vitest/pytest/JUnit/Go test]"
  e2e_tool: "[Playwright/Cypress/Selenium]"

# What are we testing?
test_scope:
  - area: "[e.g., Auth module]"
    risk: high
    test_types: [unit, integration, e2e]
    priority: 1
  - area: "[e.g., Settings page]"
    risk: low
    test_types: [unit]
    priority: 3

# What's NOT in scope (and why)
exclusions:
  - "[e.g., Third-party widget — covered by vendor]"

# Quality targets
targets:
  line_coverage: 80
  branch_coverage: 70
  critical_path_coverage: 100
  max_flaky_rate: 2%
  max_test_duration_unit: 10ms
  max_test_duration_integration: 500ms
  max_test_duration_e2e: 30s

Risk-Based Test Allocation

Not everything needs the same testing depth. Use the risk matrix:

Risk Level	Unit Tests	Integration	E2E	Manual/Exploratory
Critical (payments, auth, data loss)	95%+ coverage	Full API coverage	Happy + error paths	Exploratory session
High (core features, user-facing)	85%+ coverage	Key integrations	Happy path	Spot check
Medium (secondary features)	70%+ coverage	Critical paths only	Smoke only	On release
Low (admin, internal tools)	50%+ coverage	None	None	None

Test Pyramid

Follow the pyramid — not the ice cream cone:

         /  E2E  \          ← Few (5-10%) — slow, expensive, brittle
        / Integr. \         ← Some (15-25%) — API contracts, DB queries
       /   Unit    \        ← Many (65-80%) — fast, isolated, cheap

Anti-pattern: Ice cream cone (mostly E2E, few unit tests) = slow CI, flaky builds, expensive maintenance.

Decision rule: Can this be tested at a lower level? → Test it there.

Phase 2: Unit Testing

Anatomy of a Good Unit Test

Every unit test follows AAA (Arrange-Act-Assert):

1. ARRANGE — Set up test data, mocks, state
2. ACT     — Call the function/method under test
3. ASSERT  — Verify the output matches expectations

Unit Test Checklist (per function)

For each function/method, verify:

Happy path — expected input → expected output
Edge cases — empty input, null/undefined, zero, max values
Boundary values — off-by-one, min-1, max+1
Error handling — invalid input → correct error thrown
Return types — correct type, shape, structure
Side effects — does it modify state it shouldn't?
Idempotency — calling twice gives same result?

What to Mock (and What NOT to Mock)

Mock these:

External APIs (HTTP calls, third-party services)
Database queries (in unit tests only)
File system operations
Date/time (use fake timers)
Random number generators
Environment variables

DO NOT mock these:

The function under test itself
Pure utility functions (test them directly)
Data transformations
Simple value objects

Mock rule of thumb: If removing the mock would make the test hit the network, file system, or database → mock it. Otherwise → don't.

Test Naming Convention

Use the pattern: [unit] [scenario] [expected result]

Examples:

calculateTotal returns 0 for empty cart
validateEmail throws for missing @ symbol
parseDate handles ISO 8601 with timezone offset

Coverage Analysis

Metrics that matter:

Metric	Target	Why
Line coverage	80%+	Basic completeness
Branch coverage	70%+	Catches missed if/else paths
Function coverage	90%+	Ensures all functions are tested
Critical path coverage	100%	Business-critical code fully verified

Coverage traps to avoid:

100% line coverage ≠ good tests (assertions matter more than lines hit)
Coverage on generated code inflates numbers
Trivial getters/setters pad coverage without value
Coverage should INCREASE over time, never decrease

Phase 3: Integration Testing

What Integration Tests Cover

Integration tests verify that components work TOGETHER:

API endpoint → middleware → handler → database → response
Service A calls Service B and handles the response
Message queue producer → consumer → side effect
Auth flow: login → token → authenticated request

Integration Test Patterns

Pattern 1: API Contract Testing

1. Start test server (or use supertest/httptest)
2. Send HTTP request with specific payload
3. Assert: status code, response body shape, headers
4. Assert: database state changed correctly
5. Assert: side effects triggered (emails, events)

Pattern 2: Database Integration

1. Start test database (SQLite in-memory or test container)
2. Run migrations
3. Seed test data
4. Execute query/operation
5. Assert: data matches expectations
6. Teardown (truncate or rollback transaction)

Pattern 3: External Service

1. Record real API response (VCR/nock/wiremock)
2. Replay recorded response in tests
3. Assert: your code handles the response correctly
4. Also test: timeout, 500 error, malformed response

Integration Test Checklist

Happy path — full flow works end-to-end
Auth — unauthenticated returns 401, wrong role returns 403
Validation — bad payload returns 400 with error details
Not found — missing resource returns 404
Conflict — duplicate create returns 409
Rate limiting — excessive requests return 429
Database constraints — unique violations, foreign keys
Concurrency — two simultaneous writes don't corrupt data
Timeout handling — external service timeout → graceful fallback

Phase 4: End-to-End (E2E) Testing

E2E Strategy

E2E tests verify complete user journeys. They're expensive — be strategic:

Test these E2E:

User registration → email verification → first login
Purchase flow → payment → confirmation
Critical business workflows (the ones that make money)
Cross-browser/device smoke tests

DON'T test these E2E:

Individual form validations (unit test)
API error handling (integration test)
Edge cases (lower-level tests)
Visual styling (visual regression tools)

E2E Test Template

test_name: "[User journey name]"
preconditions:
  - "[User is logged in]"
  - "[Product exists in catalog]"
steps:
  - action: "Navigate to /products"
    verify: "Product list is visible"
  - action: "Click 'Add to Cart' on Product A"
    verify: "Cart badge shows 1"
  - action: "Click 'Checkout'"
    verify: "Checkout form displayed"
  - action: "Fill payment details and submit"
    verify: "Order confirmation page with order ID"
postconditions:
  - "Order exists in database with status 'paid'"
  - "Confirmation email sent"
max_duration: 30s

Flaky Test Management

Flaky tests are the #1 CI killer. Handle them:

Flaky Test Triage:

Identify — Track test pass rates over 10+ runs
Classify — Why is it flaky?
- Timing/race condition → Add explicit waits, not sleep()
- Test data dependency → Isolate test data per run
- External service → Mock it or use test container
- Browser rendering → Use visibility checks, not delays
Quarantine — Move to @flaky suite, run separately
Fix or delete — Flaky test unfixed for 2 weeks → delete it

Flaky rate target: < 2% of total test runs

Phase 5: Performance Testing

Performance Test Types

Type	Purpose	When
Load test	Normal traffic handling	Before every release
Stress test	Find breaking point	Quarterly or before scaling
Spike test	Sudden traffic burst	Before marketing campaigns
Soak test	Memory leaks over time	Monthly or after major changes
Capacity test	Max users/throughput	Planning infrastructure

Performance Test Plan

test_name: "[API/Page] Load Test"
target: "[URL or endpoint]"
baseline:
  p50_response: "[current p50 ms]"
  p95_response: "[current p95 ms]"
  p99_response: "[current p99 ms]"
  error_rate: "[current %]"

scenarios:
  - name: "Normal load"
    vus: 50          # virtual users
    duration: 5m
    ramp_up: 30s
    thresholds:
      p95_response: "< 500ms"
      error_rate: "< 1%"

  - name: "Peak load"
    vus: 200
    duration: 10m
    ramp_up: 1m
    thresholds:
      p95_response: "< 2000ms"
      error_rate: "< 5%"

  - name: "Stress test"
    vus: 500
    duration: 5m
    ramp_up: 2m
    # Find the breaking point — no thresholds, observe

Performance Metrics Dashboard

Track these per endpoint:

Metric	Green	Yellow	Red
p50 response	< 200ms	200-500ms	> 500ms
p95 response	< 500ms	500ms-2s	> 2s
p99 response	< 1s	1-5s	> 5s
Error rate	< 0.1%	0.1-1%	> 1%
Throughput	> baseline	80-100% baseline	< 80%
CPU usage	< 60%	60-80%	> 80%
Memory usage	< 70%	70-85%	> 85%
DB query time	< 50ms avg	50-200ms	> 200ms

Common Performance Fixes

Symptom	Likely Cause	Fix
Slow API response	N+1 queries	Batch/join queries
Memory climbing	Object retention	Profile heap, fix leaks
Timeout spikes	Connection pool exhaustion	Increase pool, add queuing
Slow page load	Large bundle	Code split, lazy load
DB bottleneck	Missing index	Add index on WHERE/JOIN columns
High CPU	Synchronous compute	Move to worker/queue

Phase 6: Security Testing

Security Test Checklist

Run through these for every feature/release:

Authentication & Authorization:

Passwords hashed with bcrypt/argon2 (not MD5/SHA1)
Session tokens are random, sufficient length (128+ bits)
JWT tokens have short expiry (15 min access, 7 day refresh)
Failed login rate limiting (5 attempts → lockout)
Password reset tokens expire (1 hour max)
Role-based access enforced server-side (not just UI)
Can't access other users' data by changing IDs in URL

Input Validation:

SQL injection — parameterized queries everywhere
XSS — output encoding, CSP headers
CSRF — tokens on state-changing requests
Path traversal — validate file paths, no ../
Command injection — never pass user input to shell
File upload — validate type, size, scan for malware
JSON/XML parsing — depth limits, entity expansion disabled

Data Protection:

HTTPS everywhere (HSTS header)
Sensitive data encrypted at rest
PII not logged (mask in log output)
API keys not in client-side code
CORS configured correctly (not *)
Security headers set (X-Frame-Options, X-Content-Type-Options)

Infrastructure:

Dependencies scanned for CVEs (npm audit / pip audit)
Docker images scanned (Trivy/Snyk)
Secrets not in code/env files (use vault)
Error messages don't leak internals
Admin endpoints behind VPN/IP allowlist

P2 Medium	Feature broken with workaround	Fix this sprint	Search returns wrong results sometimes
P3 Low	Minor issue, cosmetic	Fix when convenient	Button alignment off by 2px

Bug Triage Process (Weekly)

1. Review all new bugs (unassigned)
2. For each bug:
   a. Reproduce — can you trigger it?
   b. Classify severity (P0-P3)
   c. Estimate fix effort (S/M/L)
   d. Assign to owner + sprint
   e. Link to related bugs/stories
3. Review P0/P1 bugs from last week — are they fixed?
4. Close bugs that can't be reproduced (after 2 attempts)
5. Update metrics dashboard

Bug Metrics Dashboard

Track weekly:

Metric	Formula	Target
Bug escape rate	Bugs found in prod / total bugs	< 10%
Mean time to fix (P0)	Avg hours from report to deploy	< 8 hours
Mean time to fix (P1)	Avg hours from report to deploy	< 48 hours
Bug reopen rate	Reopened bugs / closed bugs	< 5%
Test escape analysis	Bugs that SHOULD have been caught	Track & reduce
Open bug count	Total open by severity	Trending down

Test Maintenance Rules

No commented-out tests — delete or fix, never comment
No skipped tests > 2 weeks — fix or remove
No test duplication — each behavior tested once at the right level
Test names must be readable — someone new should understand what broke
Shared test utilities — common setup in fixtures/factories, not copy-pasted
Test data isolation — each test creates its own data, cleans up after
No magic numbers — use named constants in assertions
Assertion messages — custom messages on complex assertions

Common Test Anti-Patterns

Anti-Pattern	Problem	Fix
Sleeping tests	`sleep(2000)` instead of waiting	Use explicit waits/polling
Test interdependence	Test B relies on Test A's state	Isolate — each test sets up its own state
Assertionless tests	Test runs code but doesn't assert	Add meaningful assertions
Brittle selectors	CSS selectors that break on redesign	Use data-testid or aria roles
God test	One test verifying 20 things	Split into focused tests
Mock overload	Everything mocked, nothing real tested	Only mock external boundaries
Hardcoded data	Tests break when seed data changes	Use factories/builders
Ignoring test output	"It passed, ship it"	Review WHY it passed — is the assertion meaningful?
