How can I use GoMock for advanced testing scenarios?

GoMock is a powerful tool for creating mock objects in Go. For advanced scenarios, you can use custom matchers and define expectations on method calls.

Can you give me an example of using custom matchers?

Sure! You can create a custom matcher by implementing the Matcher interface. For instance, if you want to match a specific struct, you can define a matcher that checks the fields of that struct.

What about handling multiple return values?

You can specify multiple return values in your mock by using the Return method. Just chain it after your method call expectation.

Is there a way to verify that a method was called a specific number of times?

Yes, you can use the Times method to specify how many times you expect a method to be called. For example, mock.EXPECT().MethodName().Times(2).
