Overview

Command-line front end. Three real commands:

run     boots the target suite under coverage instrumentation -> run.json
report  analyzes run.json and prints grouped candidates (read-only)
apply   prompts for approval, then writes a removal patch (never edits in place)

  testprune — audit a Ruby test suite for redundant coverage

  Usage:
    testprune scan [options] [-- <test command>]
    testprune report [options]
    testprune apply [options]
    testprune prune [options] [-- <test command>]

  Commands:
    scan     Run the target suite instrumented; capture per-test coverage + timing
    report   Analyze captured data and print removal candidates (read-only)
    apply    Review candidates, ask for approval, emit a git-applyable patch
    prune    Run scan + apply in one step (the full workflow)

  Options:
    -s, --source PATH      Source dir to analyze (repeatable; default: app, lib)
    -o, --output DIR       Output dir for captured data (default: .testprune)
        --baseline FRAC    Treat units run by >= FRAC of tests as shared-setup
                           noise and subtract them (0..1; default 0.5; 0 to disable)
        --json             Emit machine-readable JSON (report only)
    -h, --help             Show this help
    -v, --version          Show version
