## Test Coverage Analysis

### AC1.4: PERFORMANCE.md Documentation Validation

The testing strategy specified manual verification steps:
1. `cat PERFORMANCE.md | grep -E '(Methodology|Results|Breakdown|Comparison)'` - verifies all sections exist
2. Verify document includes actual benchmark numbers from criterion output
3. Verify speedup ratio ≥50x is documented
4. Verify reproduction instructions are present

**Coverage Status**: ✅ COMPLETE

All manual verification steps have been **automated** into comprehensive test suite:

#### Tests Created (15 new tests in `tests/test_performance_documentation.rs`):

1. **test_performance_md_exists** - Validates file exists and is not empty
2. **test_all_required_sections_present** - Validates all 6 required sections (Methodology, Results, Breakdown, Comparison, Variance, Reproduction)
3. **test_methodology_section_complete** - Validates hardware specs, benchmark framework, statistical methods
4. **test_results_section_has_benchmark_numbers** - Validates actual benchmark data (mean, std dev, CI, CV)
5. **test_breakdown_section_has_pipeline_stages** - Validates performance breakdown by stage (lexing, parsing, compilation, VM)
6. **test_comparison_section_documents_speedup** - Validates CPython comparison with speedup analysis
7. **test_speedup_ratio_at_least_50x_documented** - Validates AC1.3 (≥50x speedup) is documented
8. **test_variance_section_reports_statistical_confidence** - Validates AC1.5 (CV < 10%) is documented
9. **test_reproduction_instructions_present** - Validates reproduction commands (`cargo bench`)
10. **test_cold_start_performance_documented** - Validates AC1.2 (< 100μs) is documented
11. **test_acceptance_criteria_validation_section** - Validates all Phase 1 ACs are proven
12. **test_comprehensive_ac14_validation** - Comprehensive validation of all AC1.4 requirements

#### Edge Case Tests (3 tests):

13. **test_edge_case_document_not_truncated** - Ensures document is complete (> 2KB)
14. **test_edge_case_no_placeholder_text** - Ensures no TODO/TBD/FIXME placeholders
15. **test_edge_case_markdown_formatting_valid** - Validates basic markdown structure

#### Existing Benchmark Validation Tests (8 tests in `tests/benchmark_validation.rs`):

1. **test_cold_start_performance_meets_ac12** - Validates AC1.2 (< 100μs mean)
2. **test_benchmark_stability_meets_ac15** - Validates AC1.5 (CV < 10%)
3. **test_all_required_benchmarks_exist** - Validates benchmark suite completeness
4. **test_html_reports_generated** - Validates Criterion HTML reports
5. **test_benchmark_json_schema_valid** - Validates JSON output structure
6. **test_edge_case_empty_program_benchmark** - Edge case: empty program
7. **test_edge_case_all_operators_benchmark** - Edge case: all operators
8. **test_warm_vs_cold_benchmarks_both_exist** - Validates both benchmark types

## Manual Verification (from Testing Strategy)

All manual verification steps from the testing strategy have been executed:

### ✅ Step 1: Verify all sections exist
```bash
$ grep -c "Methodology\|Results\|Breakdown\|Comparison" PERFORMANCE.md
9
```
**Result**: All required sections found

### ✅ Step 2: Verify benchmark numbers from criterion output
**Test**: test_results_section_has_benchmark_numbers
**Result**: Document contains actual timing data (293.34 ns, confidence intervals, CV, etc.)

### ✅ Step 3: Verify speedup ratio ≥50x is documented
```bash
$ grep -c "Speedup" PERFORMANCE.md
18
```
**Result**: Speedup analysis present, documents 66,054x speedup (exceeds 50x requirement)

### ✅ Step 4: Verify reproduction instructions
```bash
$ grep "cargo bench" PERFORMANCE.md | head -5
cargo bench
cargo bench --bench startup_benchmarks
cargo bench --bench execution_benchmarks
cargo bench --bench cpython_baseline
cargo bench --bench startup_benchmarks
```
**Result**: Comprehensive reproduction instructions present
