Audit Rules

1. Framework Tests Detection

What: Tests validating framework behavior (Express, Fastify, Koa) instead of OUR business logic

Detection Patterns:

(express|fastify|koa).(use|get|post|put|delete|patch)
Test names: "middleware is called", "route handler works", "Express app listens"

Severity: MEDIUM

Recommendation: DELETE — framework already tested by maintainers

Effort: S (delete test file or test block)

2. ORM/Database Library Tests

What: Tests validating Prisma/Mongoose/Sequelize/TypeORM behavior

Detection Patterns:

(prisma|mongoose|sequelize|typeorm).(find|findMany|create|update|delete|upsert)
Test names: "Prisma findMany returns array", "Mongoose save works"

Severity: MEDIUM

Recommendation: DELETE — ORM already tested

Effort: S

3. Crypto/Hashing Library Tests

What: Tests validating bcrypt/argon2 hashing behavior

Detection Patterns:

(bcrypt|argon2).(hash|compare|verify|hashSync)
Test names: "bcrypt hashes password", "argon2 compares correctly"

Severity: MEDIUM

Recommendation: DELETE — crypto libraries already tested

Effort: S

4. JWT/Token Library Tests

What: Tests validating JWT signing/verification

Detection Patterns:

(jwt|jsonwebtoken).(sign|verify|decode)
Test names: "JWT signs token", "JWT verifies signature"

Severity: MEDIUM

Recommendation: DELETE — JWT library already tested

Effort: S

5. HTTP Client Library Tests

What: Tests validating axios/fetch/got behavior

Detection Patterns:

(axios|fetch|got|request).(get|post|put|delete|patch)
Test names: "axios makes GET request", "fetch returns data"

Severity: MEDIUM

Recommendation: DELETE — HTTP clients already tested

Effort: S

6. React Hooks/Framework Tests

What: Tests validating React hooks behavior (useState, useEffect, etc.)

Detection Patterns:

(useState|useEffect|useContext|useReducer|useMemo|useCallback)
Test names: "useState updates state", "useEffect runs on mount"

Severity: LOW (acceptable if testing OUR custom hook logic)

Recommendation: REVIEW — if testing framework behavior → DELETE; if testing custom hook → KEEP

Effort: S-M

Scoring Algorithm

penalty = (medium * 0.5) + (low * 0.2)
score = max(0, 10 - penalty)
