## `notDeepEqual( actual, expected [, message ] )`
An inverted deep recursive comparison, working on primitive types, arrays, objects, regular expressions, dates and functions.
| name | description |
|--------------------|--------------------------------------|
| `actual` | Expression being tested |
| `expected` | Known comparison value |
| `message` (string) | A short description of the assertion |
### Description
The `notDeepEqual()` assertion can be used just like `equal()` when comparing the value of objects, such that `{ key: value }` is equal to `{ key: value }`. For non-scalar values, identity will be disregarded by `notDeepEqual`.
[`deepEqual()`](/assert/deepEqual) can be used to explicitly test deep, strict equality.
### Examples
Compare the value of two objects.
```js
QUnit.test( "notDeepEqual test", function( assert ) {
var obj = { foo: "bar" };
assert.notDeepEqual( obj, { foo: "bla" }, "Different object, same key, different value, not equal" );
});
```
