我有一个类,它在它的构造函数中使用一个 IRepository 像这样......
public class UserService
{
public IRepository<User> _repo { get; set; }
public UserService(IRepository<User> repo = null)
{
_repo = repo ?? new UserRepository();
}
并有一个看起来像这样的方法......
public bool IsUserActive(email string)
{
//The method actually does more but to keep it simple lets imagine
// it does this
User user = _repo.Find(u => u.Email == email).First();
return user.IsActive;
}
IRepository 看起来像这样。
public interface IRepository<T> : IDisposable where T : IEntity
{
void InsertOrUpdate(T entity);
void Delete(T entity);
IQueryable<T> Find(Func<T, bool> query);
T Find(int id);
void Save();
}
我想测试该IsUserActive
方法并确保如果IsActive
用户的字段为 false 则返回 false,反之亦然。
我正在尝试以下...
[Test]
public void IsUserActive_EmailThatWillReturnInactiveUser_ReturnsFalse()
{
//Arrange
var fakeUserRepo = new Mock<IRepository<User>>();
var query = new Func<User, bool>(u => u.Email == "AnyString");
var listOfMatchingUsers = new List<User>()
{
new User
{
Email = "AnyString",
IsActive = False
}
};
IQueryable<User> queryableUsers = listOfMatchingUsers.AsQueryable();
fakeUserRepo.Setup(r => r.Find(query)).Returns(queryableUsers);
var userService = new UserService(fakeUserRepo.Object);
//Act
var result = userService.IsUserActive("AnyString");
//Assert
Assert.IsFalse(result);
}
当我在 NUnit 中运行时,我在这一行收到错误“序列不包含元素”
var result = userService.IsUserActive("AnyString");
我哪里错了?
