cfwaretap-yaml-summary 
Output a summary in YAML format from a TAP stream
Target User
This produces intentionally bare bones summaries. The primary target is modules with stable testing. If you are looking for a pretty output look elsewhere.
Command-line usage
tap test/*.js | tap-yaml-summary
API
This module works as a transform stream
const Reporter = require('tap-yaml-summary');
fs.createReadStream('saved-test-output.tap')
.pipe(new Reporter().on('error', () => process.exit(1)))
.pipe(process.stdout);
The error event is emitted on completion if any assertion failed or a bailout occurred.
