assert.notOk()

version added: 1.18.0.

notOk( state, message = "" )

A boolean check that passes when the first argument is falsy.

name	description
`state`	Expression being tested
`message` (string)	Short description

This assertion requires only one argument. If the argument evaluates to false, the assertion passes; otherwise, it fails.

To strictly compare against boolean false, use assert.false().

Examples

QUnit.test('example', assert => {
  // success
  assert.notOk(false, 'boolean false');
  assert.notOk('', 'empty string');
  assert.notOk(0, 'number zero');
  assert.notOk(NaN, 'NaN value');
  assert.notOk(null, 'null value');
  assert.notOk(undefined, 'undefined value');

  // failure
  assert.notOk('foo', 'non-empty string');
  assert.notOk(true, 'boolean true');
  assert.notOk(1, 'number one');
});
