Rust Test Quality Analysis Module

Provides comprehensive analysis of Rust test code quality, detecting patterns that indicate potential issues in test suites.

Components

• analyzer: Main orchestrator for Rust test analysis
• assertion_detector: Detects missing or weak assertions
• complexity_scorer: Measures test complexity
• flaky_detector: Identifies flaky test patterns
• framework_detector: Detects test frameworks (std, criterion, proptest, rstest)
• test_classifier: Classifies tests by type

Test Quality Metrics

Assertion Analysis

• Counts assertions per test (assert!, assert_eq!, assert_ne!)
• Detects tests with no assertions
• Identifies Result-based tests
• Tracks \[should_panic\] usage

Complexity Scoring

• Conditional statements: +2 per if/match
• Loops: +3 per loop
• Assertions: +1 per assertion beyond 5
• Nesting depth: +2 per level > 2
• Line count: +(lines-30)/10 for tests > 30 lines

Flaky Pattern Detection

• Timing: std::thread::sleep, Instant::now()
• Random: rand crate usage
• External: Network calls, filesystem hardcoded paths
• Threading: Unsynchronized concurrent access
• Hash ordering: HashMap iteration

Framework Detection

• Standard \[test\] attribute
• Criterion benchmarks
• Proptest property tests
• Rstest parameterized tests
