Example

Printing results of a test suite.

QUnit.on( "runEnd", function( data ) {
  console.log( "Passed: " + data.testCounts.passed );
  console.log( "Failed: " + data.testCounts.failed );
  console.log( "Skipped: " + data.testCounts.skipped );
  console.log( "Todo: " + data.testCounts.todo );
  console.log( "Total: " + data.testCounts.total );
} );

Using modern syntax:

QUnit.on( "runEnd", ( { testCounts: { passed, failed, skipped, todo, total } } ) => {
  console.log( `Passed: ${passed}` );
  console.log( `Failed: ${failed}` );
  console.log( `Skipped: ${skipped}` );
  console.log( `Todo: ${todo}` );
  console.log( `Total: ${total}` );
} );
