QUnit.begin( callback )

Register a callback to fire whenever the test suite begins. The callback can return a promise that will be waited for before the next callback is handled.

QUnit.begin() is called once before running any tests.

Get total amount of tests.

QUnit.begin(function( details ) {
  console.log( "Test amount:", details.totalTests );

Using modern syntax:

QUnit.begin( ( { totalTests } ) => {
  console.log( `Test amount: ${totalTests}` );

  return new Promise(function(resolve, reject) {
