File contents

Test Framework Skill (Mega-Skill)

Version: 1.0.0 Purpose: Test execution, running, and webapp testing for CFN Status: Production Consolidates: cfn-test-execution, cfn-test-runner, cfn-webapp-testing

Overview

This mega-skill provides complete testing capabilities:

Execution - Test suite execution and reporting
Runner - Test process management and parallelization
Webapp - Browser-based webapp testing (Playwright)

Running Tests (standard capture pattern)

Capture full output to a project-unique file, then read the file for all errors in one run. No watch mode, no bail/fail-fast flag.

OUT=/tmp/test-${PWD##*/}-$(date +%s).txt
<test-cmd> 2>&1 | tee "$OUT"
# then read "$OUT" for the complete failure set

${PWD##*/} plus the timestamp keeps the filename unique across concurrent project runs.
Use vitest run (not vitest), drop -x/--bail/--fail-fast, keep verbose + full traces so every failure shows on the first pass.
Compile errors are not test failures: dump all compile errors first (tsc --noEmit, cargo check --message-format=short, go build ./...) before blaming tests.
Leaked workers: if a runner dies and orphans worker processes (reparented to PID 1), .claude/hooks/reap-orphan-test-workers.sh reaps them so they do not burn CPU/RAM.
