Small script to get the list of tests that were executed in a try run

get-test-list.js

async function getTestList(logUrl) {
  let log = await fetch(logUrl);
  let logText = await log.text();
  let lines = logText.split("\n");
  lines = lines
            .filter(l => l.includes("TEST-START"))
            .filter(l => !l.includes("Shutdown"))
            .map(l => l.match(/TEST-START \| ([^\s]+)/)[1]);

  console.log(lines);
} 

getTestList("https://public-artifacts.taskcluster.net/X5kX9lNMTb27GBSLWg6X9Q/0/public/logs/live_backing.log");
