Wanted but not Invoked Error in mockito and its solution

This happens with mockito when trying to verify the invocation on an object with specific method.

But what happens is you have interacted with other method of that object but not the one mentioned.

If you have an object named CustomerService and say it has two methods named saveCustomer() and verifyExistingCustomer()

And mockito looks something like

verify(customerService, atleast(1)).verifyExistingCustomer(customer), 

But in your actual service you called the saveCustomer() at least once.. BINGO you would get that error.
