Fuzzy Assertions
^^^^^
**Definition:**

* Where lack of control for the system under test, causes us not to be able to predict the exact outcome, leading to fuzzy or partial matching in our assertions


**Code Example:**

.. code-block:: javascript

  readUser = system.retrieveUser(id)
 
  //fuzzy match
  assert(user).matches([
      { obj.firstName == 'John' },
      { obj.lastName == 'Smith' },
      { obj.id instanceof UUID },
      { obj.creationDate - now() < inSeconds(5) }
  ])
