How to use the qunit.testDone function in qunit

let deprecations;
registerDeprecationHandler((message, options, next) => {
  // in case a deprecation is issued before a test is started
  if (!deprecations) {
    deprecations = [];
  }

});

QUnit.testStart(function() {

    cleanupFailures.push(message);

    // eslint-disable-next-line
    console.error(message);
    Ember.testing = false;
  }

  // this is used to ensure that the testing container is always reset properly
  let testElementContainer = document.getElementById('ember-testing-container');
  let actual = testElementContainer.innerHTML;
  let expected = `<div id="ember-testing"></div>`;
  if (actual !== expected) {

        log('not ok ' + actualTestCount + ' - ' + params.module + ' - ' + params.name);
      }

  })
  QUnit.testStart( function(params){
      currentTest = {
          id: id++,
