Moq can be used to create fake delegates. Mocks faking delegates can be configured like normal methods to return a value, execute a callback or throw an exception.
The snippets below are based on the following type
public delegate int ParseString(string value);
Moq can fake explicit delegates by simply passing their type to the constructor.
var mock = new Mock<ParseString>();
Alternatively, Moq supports delegates based on
var mock = new Mock<Func<string, int>>();
It is possible to configure the delegates as if they were normal methods.
mock.Setup(p => p(It.IsAny<string>()))
var parser = Mock.Of<ParseString>();
var func = Mock.Of<Func<string, int>>();
