assert.false()

version added: 2.11.0.

Description

false( actual, message = "" )

A strict comparison that passes if the first argument is boolean false.

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

This method is similar to the assertFalse() method found in xUnit-style frameworks.

assert.true() can be used to explicitly test for a true value.

Examples

QUnit.test('example', assert => {
  // success
  assert.false(false, 'boolean false');

  // failure
  assert.false('foo', 'non-empty string');
  assert.false('', 'empty string');
  assert.false(0, 'number zero');
  assert.false(true, 'boolean true');
  assert.false(NaN, 'NaN value');
  assert.false(null, 'null value');
  assert.false(undefined, 'undefined value');
});
