What are the best practices for using GoMock in testing?

When using GoMock, it's important to define clear expectations for your mocks, use the right matchers, and keep your tests isolated.

Can you explain how to set up GoMock for a simple function?

Sure! First, you need to install GoMock and its code generation tool. Then, create an interface for the function you want to mock.

What are some common pitfalls to avoid when using GoMock?

Common pitfalls include not resetting mocks between tests, overusing mocks instead of real implementations, and not checking for expected calls.

How do I verify that my mock was called with the correct parameters?

You can use the EXPECT() method to set expectations on your mock, specifying the parameters it should be called with.

Are there any performance considerations when using GoMock?

Yes, excessive mocking can slow down your tests. It's best to use mocks judiciously and prefer real implementations when possible.
