assert.step()

version added: 2.2.0.

Description

step( value )

Record a step for later verification.

name description
value (string) Relevant string value, or short description, to mark this step.

This assertion registers a passing assertion with the provided string. This and any other steps should be verified later in the test via assert.verifySteps().

The Step API provides an easy way to verify execution logic to a high degree of accuracy and precision, whether for asynchronous code, event-driven code, or callback-driven code.

Examples

QUnit.test('example', function (assert) {
  var maker = new WordMaker();
  maker.on('start', () => {
    assert.step('start');
  });
  maker.on('data', (word) => {
    assert.step(word);
  });
  maker.on('end', () => {
    assert.step('end');
  });

  maker.process('3.1');

  assert.verifySteps([ 'start', '3', 'point', '1', 'end' ]);
});

Note: See assert.verifySteps() for more detailed examples.
