< code > isTrue()< / code > will test for the boolean value true and < code > isNotTrue()< / code > will pass when given anything but the boolean value of true.

```js
assert.isTrue(true, 'this will pass with the boolean value true');
assert.isTrue('true', 'this will NOT pass with the string value 'true');
2019-04-19 13:04:53 +00:00
assert.isTrue(1, 'this will NOT pass with the number value 1');

```

< code > isFalse()< / code > and < code > isNotFalse()< / code > also exist and behave similary to their true counterparts except they look for the boolean value of false.
