I have a method on my interface that looks like:
T GetSingle(Expression<Func<T, bool>> criteria);
I'm trying to mock the setup something like this (I realise this isn't working):
_mockUserRepository = new Mock<IRepository<User>>();
_mockUserRepository.Setup(c => c.GetSingle(x => x.EmailAddress == "a@b.com"))
.Returns(new User{EmailAddress = "a@b.com"});
I realise I'm passing in the wrong parameter to the setup.
After reading this answer I can get it working by passing in the Expression, like this:
_mockUserRepository.Setup(c => c.GetSingle(It.IsAny<Expression<Func<User, bool>>>())
.Returns(new User{EmailAddress = "a@b.com"});
However, this means if I call the GetSingle
method with any expression, the same result is returned.
Is there a way of specifying in the setup, what Expression to use?
