Mockito

Creating a Mock

• See Mock Objects

Verify

• Once created, a mock will remember its interactions which we can verify later
• We can verify the value of an interaction and the amount of times it was done
• Asserts check returned values where verify checks if an interaction actually happened
• We can also verify interactions in order

Stubbing

• Return the hard coded value we passed in
• The method will always return the stubbed value if called

Argument Captor

• Captures the value that is passed in
• Then we call verify and ask what was passed in

Spying

• You can create spies, where when you use the spy, the real methods are called unless they were stubbed.
• Avoid use since there are a ton of gotchas here.
