assert.timeout()

version added: 2.4.0.

timeout( duration )

Set how long to wait for async operations to finish.

name	description
`duration` (number)	The length of time to wait, in milliseconds.

This assertion defines how long to wait (at most) in the current test. It overrides QUnit.config.testTimeout on a per-test basis.

The timeout length only applies when a test actually involves asynchronous functions or promises. If 0 is passed, then awaiting or returning any Promise may fail the test.

If assert.timeout() is called after a different timeout is already set, the old timeout will be cleared and the new duration will be used to start a new timer.

Examples

QUnit.test('wait for an event', assert => {
  assert.timeout(1000); // Timeout after 1 second
  const done = assert.async();

  const adder = new NumberAdder();
  adder.on('ready', res => {
    assert.strictEqual(res, 12);
    done();
  });
  adder.run([ 1, 1, 2, 3, 5 ]);
});

QUnit.test('wait for an async function', async assert => {
  assert.timeout(500); // Timeout after 0.5 seconds

  const result = await asyncAdder(5, 7);
  assert.strictEqual(result, 12);
});

Using classic ES5 syntax:

QUnit.test('wait for a returned promise', function (assert) {
  assert.timeout(500); // Timeout after 0.5 seconds

  var promise = asyncAdder(5, 7);

  return promise.then(function (result) {
    assert.strictEqual(result, 12);
  });
});
