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.

parameter description
callback (function) Callback to execute. Provides a single argument with the callback details object

Callback details: callback( details: { totalTests } )

parameter description
totalTests The number of total tests in the test suite

Example

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}` );
});

Returning a promise:

QUnit.begin( () => {
  return new Promise(function(resolve, reject) {
    // do some async work
    resolve();
  });
});
