assert.ok() - Qunit — ContextQMD

ok( state, message = "" )

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

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

If the argument is true or casts to true, the assertion passes; otherwise, it fails.

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

For the inverse of ok(), refer to assert.notOk()

Examples

QUnit.test('example', function (assert) {
  // success
  assert.ok(true, 'boolean true');
  assert.ok('foo', 'non-empty string');
  assert.ok(1, 'number one');

  // failure
  assert.ok(false, 'boolean false');
  assert.ok('', 'empty string');
  assert.ok(0, 'number zero');
  assert.ok(NaN, 'NaN value');
  assert.ok(null, 'null value');
  assert.ok(undefined, 'undefined value');
