How do I use Mockito to verify an order in my tests?

You can use Mockito's verify() method to check if a specific method was called on a mock object. For example, if you have a mock of an OrderService, you can verify that the placeOrder() method was called.

Can you show me a code example?

Sure! Here's a simple example:

OrderService orderService = mock(OrderService.class);
orderService.placeOrder(order);

// Verify that placeOrder was called with the correct order
verify(orderService).placeOrder(order);

What if I want to verify the number of times a method was called?

You can use the times() method with verify(). For example:

verify(orderService, times(2)).placeOrder(order);
``` This checks that `placeOrder()` was called exactly twice.

Is there a way to verify that a method was never called?

Yes! You can use verifyZeroInteractions() or verify(orderService, never()).placeOrder(order); to ensure that the method was never called.
