UnitTest

using MoqExpression;

Mock<IUserService> mockUserService = new Mock<IUserService>();
mockUserService.Setup(x => x.FindByUserId(MoqHelper.IsExpression<User>(s => s.UserId.Equals("123")))).Returns(user);

Note: Make sure don't use like this, it will not work.

// don't use like this it will not work 
Expression<Func<User, bool>> expression = MoqHelper.IsExpression<User>(s => s.UserId.Equals("123"));
mockUserService.Setup(x => x.FindByUserId(expression)).Returns(user);

// use equal function instead of ==
mockUserService.Setup(x => x.FindByUserId(MoqHelper.IsExpression<User>(s => s.UserId == "123"))).Returns(user);
