How do I test interfaces in Go?
An example of an AI chatbot conversation about testing interfaces in Go programming.
How do I test interfaces in Go?
To test interfaces in Go, you can use the built-in testing package. You create a mock implementation of the interface and then write tests against that.
Can you show me an example of a mock implementation?
Sure! Here's a simple example: if you have an interface Reader, you can create a mock struct that implements Read method for testing.
What about using third-party libraries for mocking?
You can use libraries like gomock or testify for more complex mocking scenarios, which can simplify your tests.
