====== Mockito ======

===== Mocks =====

===== Spies =====

===== Argument Matchers =====
  * we can configure our mocked methods with argument matchers
<code java>
when(flowerService.analyze(anyString())).thenReturn("Flower");
</code>

  * **We can't use argument matchers as a return value**, an exact value is required when stubbing calls
  * we can't use argument matchers outside of verification or stubbing
===== BDDMockito =====
