coverage

Overview ¶

Package coverage integrates Go test coverage analysis.

The coverage package runs `go test -cover` on packages and parses the output to extract coverage percentages. It supports: - Configurable timeouts per package - Automatic exclusion of testdata and vendor packages - Coverage threshold detection

Usage ¶

Create a coverage runner with timeout:

runner := coverage.NewRunner(30) // 30 second timeout

Run coverage analysis:

results, err := runner.RunCoverage("/path/to/project", excludePatterns)
if err != nil {
    log.Fatal(err)
}

for _, result := range results {
    if result.Skipped {
        fmt.Printf("Skipped: %s (no tests)\n", result.PackagePath)
    } else if result.Error != "" {
        fmt.Printf("Error: %s - %s\n", result.PackagePath, result.Error)
    } else {
        fmt.Printf("%s: %.1f%%\n", result.PackagePath, result.Coverage)
    }
}

The runner automatically skips packages without tests and handles compilation errors gracefully.
