Test Smell Detection

Identifies antipatterns and code smells in PHP test suites.

15 Test Smells

# Smell Severity Detection Pattern
1 Logic in Test High if/for/while/foreach in tests
2 Mock Overuse High >3 mocks in single test
3 Test Interdependence High static $, @depends
4 Fragile Test High expects(exactly), at()
5 Mystery Guest Medium file_get_contents, getenv
6 Eager Test Medium Multiple unrelated assertions
7 Assertion Roulette Medium >5 assertions without context
8 Obscure Test Low test_it_works, test_foo
9 Test Code Duplication Medium Repeated setup/assertion
10 Conditional Test Logic Medium if.*assert patterns
11 Hard-Coded Test Data Low Magic values in tests
12 Testing Private Methods High setAccessible(true)
13 Slow Test Medium sleep, I/O in unit tests
14 Mocking Final Classes High Mock concrete final classes
15 Mocking Value Objects High Mock readonly/immutable classes

Quick Detection Commands

# Logic in tests
Grep: "if \(|for \(|while \(|foreach \(" --glob "tests/**/*Test.php"

# Mock overuse (manual count needed)
Grep: "createMock|createStub" --glob "tests/**/*Test.php"

# Test interdependence
Grep: "static \$|@depends" --glob "tests/**/*Test.php"

# Testing private methods
Grep: "setAccessible\(true\)|ReflectionMethod" --glob "tests/**/*Test.php"

# Mystery guest
Grep: "file_get_contents|fopen|getenv|_ENV|_SERVER" --glob "tests/**/*Test.php"

# Fragile tests
Grep: "expects\(.*exactly|expects\(.*at\(" --glob "tests/**/*Test.php"

Output Format

# Test Smell Report

## Summary

| Smell | Count | Severity |
|-------|-------|----------|
| Logic in Test | 5 | High |
| Mock Overuse | 3 | High |

## Findings

### Logic in Test (5 occurrences)

| File | Line | Code |
|------|------|------|
| OrderTest.php | 45 | `foreach ($items as $item)` |

**Recommendation:** Extract to data providers or inline values.

## Action Items

1. **High Priority** — Refactor tests with >5 mocks
2. **Medium Priority** — Inline fixture data

Severity Matrix

Severity Smells Impact
High Logic in Test, Mock Overuse, Test Interdependence, Fragile Test, Mocking Final/VO, Testing Private Unreliable results, design problems
Medium Mystery Guest, Eager Test, Slow Test, Conditional Logic, Duplication Hard to understand/maintain
Low Obscure Test, Hard-Coded Data Documentation/readability
