How to use Mockito Verify - JUnit Mockito Tutorial

Learn about the when you would want to use Mockito's verify assertion within unit testing and how you would use it.
In this video, I have introduced the concept of the verify assertion using an example to demonstrate how it can be beneficial to covering behaviour cases of an application where there are no return types or method calls made within the method.

i have a doubt, why u didn't stub the method calls of mocked class? they are not real methods should will not be called and return null. am i right?

[@AneeshMistry]

That’s a good spot. However the internal method call of a void method remains in place with a mock :)

[@Utub-qc2cz]

What if the methods to be tested area private ?

[@AneeshMistry]

Hey, testing private methods is often discouraged. However I have a video on how this can be done with PowerMock or ReflectionUtils. Testing private methods with Powermock

Hi @Aneesh could you explain how to write UT for a for loop.

[@AneeshMistry]

Hey Sushil! Parameterised testing may be great for for-loops!

Don't you have to train the mocks with when first?

[@AneeshMistry]

That’s a good point, you would expect this to require a spy rather than a mock. However the verify method call on a void method acknowledges the internal method calls made
