What is GoMock and how do I use it for integration testing?

GoMock is a mocking framework for Go that helps you create mock objects for testing. It allows you to define expectations and verify interactions.

Can you give me an example of how to set up a mock using GoMock?

Sure! First, you need to install GoMock. Then, you can generate a mock for your interface using the mockgen tool. Here's a simple example: mockgen -source=your_interface.go -destination=mock_your_interface.go -package=yourpackage.

How do I use the generated mock in my tests?

You can use the generated mock in your tests by creating an instance of it and setting expectations. For example: mock := &MockYourInterface{} and then use mock.EXPECT().YourMethod().Return(yourValue) to set expectations.

What are some common pitfalls to avoid when using GoMock?

Common pitfalls include not setting expectations correctly, forgetting to call the method on the mock, and not verifying the mock after the test.
