Start Coverage Collection

This feature allows you to start collecting coverage data. The code sample demonstrates how to initialize the coverage map and start the collection process.

const { createCoverageMap } = require('collect-v8-coverage');
const coverageMap = createCoverageMap();

async function startCoverage() {
  await coverageMap.startCollecting();
  console.log('Coverage collection started');
}

startCoverage();

Stop Coverage Collection

This feature allows you to stop collecting coverage data and retrieve the collected data. The code sample shows how to stop the collection and log the results.

async function stopCoverage() {
  const result = await coverageMap.stopCollecting();
  console.log('Coverage collection stopped');
  console.log(result);
}

stopCoverage();

Serialize Coverage Data

This feature allows you to serialize the collected coverage data to a file. The code sample demonstrates how to save the coverage data to a JSON file.

const fs = require('fs');

async function saveCoverageData() {
  const result = await coverageMap.stopCollecting();
  fs.writeFileSync('coverage.json', JSON.stringify(result));
  console.log('Coverage data saved to coverage.json');
}

saveCoverageData();
