How do I use GoMock for testing in Go?
To use GoMock, first install it using go get github.com/golang/mock/gomock
. Then, create a mock for your interfaces.
Can you show me an example of creating a mock?
Sure! First, generate the mock using mockgen -source=your_interface.go -destination=mock_your_interface.go
. Then, use it in your tests.
How do I set expectations on the mock?
You can set expectations using mock.EXPECT()
. For example, mock.MethodName().Return(value)
sets the return value for that method.
What if I want to test multiple scenarios?
You can create multiple instances of the mock or reset the expectations using mock.Clear()
before each test.
