Test Coverage Analysis System

Enterprise-grade test coverage analysis with comprehensive tracking of code coverage, branch coverage, and integration coverage for production-level quality assurance. Provides detailed insights into test effectiveness and identifies uncovered code paths.

Features

• Code Coverage: Line-by-line execution tracking with detailed statistics
• Branch Coverage: Decision point analysis for conditional statements
• Integration Coverage: Cross-module and cross-component coverage tracking
• Coverage Visualization: HTML reports, charts, and interactive coverage maps
• Historical Tracking: Coverage trends and regression analysis over time
• Quality Gates: Configurable coverage thresholds and pass/fail criteria
• Differential Coverage: Coverage analysis for code changes and pull requests
• Multi-format Reports: JSON, XML, LCOV, and HTML output formats
• Real-time Monitoring: Live coverage updates during test execution
• Performance Impact: Low-overhead instrumentation for production environments

Example

use scirs2_core::profiling::coverage::{
    CoverageAnalyzer, CoverageConfig, CoverageType, ReportFormat
};

// Create coverage analyzer
let config = CoverageConfig::production()
    .with_coverage_types(vec![
        CoverageType::Line,
        CoverageType::Branch,
        CoverageType::Integration
    ])
    .with_threshold(80.0)
    .with_report_format(ReportFormat::Html);

let mut analyzer = CoverageAnalyzer::new(config)?;

// Start coverage collection
analyzer.start_collection()?;

// Run your tests here...
fn run_test_suite() {
    // Example test function that would run the actual test suite
    println!("Running test suite...");
}
run_test_suite();

// Stop collection and generate report
let report = analyzer.stop_and_generate_report()?;
println!("Overall coverage: {:.2}%", report.overall_coverage_percentage());

// Check if coverage meets thresholds
if report.meets_quality_gates() {
    println!("✅ Coverage quality gates passed!");
} else {
    println!("❌ Coverage below threshold");
}
