问题描述
在对我的ASP.NET Web api控制器进行单元测试时，对于我的一个发布请求，我正在repo函数中发送两个参数，像往常一样，我正在模拟存储库设置，但是即使我发送了两个参数，我也得到了参数异常。
回购代码-
public async Task<TblUser> Register(TblUser user,string password)
{
byte[] passwordHash,passwordSalt;
CreatePasswordHash(password,out passwordHash,out passwordSalt);
user.APasswordHash = passwordHash;
user.APasswordSalt = passwordSalt;
await _context.TblUser.AddAsync(user);
await _context.SaveChangesAsync();
return user;
}
控制器代码-
[HttpPost("register")]
public async Task<IActionResult> Register(UserForRegisterDto userForRegisterDto)
{
userForRegisterDto.AUsername = userForRegisterDto.AUsername.ToLower();
if (await _repo.UserExists(userForRegisterDto.AUsername))
return BadRequest("username already exists");
if(!ModelState.IsValid || userForRegisterDto.AUsername == null || userForRegisterDto.Password == null || userForRegisterDto.AEmail ==null || userForRegisterDto.Aname ==null)
{
return BadRequest("invalid user");
}
var userToCreate = _mapper.Map<TblUser>(userForRegisterDto);
var createdUser = await _repo.Register(userToCreate,userForRegisterDto.Password);
var userToReturn = _mapper.Map<UserForDetailedDto>(createdUser);
return CreatedAtRoute("GetUser",new
{
controller = "Users",id = createdUser.ACustomerId
},userToReturn
);
}
控制器测试代码-
[Test]
public async Task GivenAValidUser_WhenIRegisteraNewUser_ThenItReturnsOkWithResponse()
{
_mockAuthRepository = new Mock<IAuthRepository>();
_mockAuthMapper = new Mock<IMapper>();
_mockConfig = new Mock<IConfiguration>();
UserForRegisterDto expectedUser = new UserForRegisterDto
{
Aname = "Luffy",AUsername = "luffy",AEmail = "[email protected]",Password = "password",Adob = new DateTime(2000,12,12)
};
_mockAuthMapper.Setup(mapper => mapper.Map<TblUser>(It.IsAny<UserForRegisterDto>()))
.Returns(new TblUser());
_mockAuthMapper.Setup(mapper => mapper.Map<UserForDetailedDto>(It.IsAny<TblUser>()))
.Returns(new UserForDetailedDto());
_mockAuthRepository.Setup(repo => repo.Register(It.IsAny<TblUser>(),It.IsAny<string>()))
.ReturnsAsync((TblUser user) => user);
_authController = new AuthController(_mockAuthRepository.Object,_mockConfig.Object,_mockAuthMapper.Object);
var tblUser = await _authController.Register(expectedUser);
var okResult = tblUser as OkObjectResult;
Assert.AreEqual(200,okResult.StatusCode);
Assert.NotNull(okResult);
Assert.IsAssignableFrom<OkObjectResult>(tblUser);
var result = ((OkObjectResult)tblUser).Value;
Assert.NotNull(result);
Assert.AreEqual(expectedUser,result);
Assert.IsAssignableFrom<TblUser>(result);
}
该异常由行引发-
_mockAuthRepository.Setup(repo => repo.Register(It.IsAny<TblUser>(),It.IsAny<string>()))
.ReturnsAsync((TblUser user) => user);
就像您看到的那样，在设置模拟存储库时，我正在发送两个参数，但出现错误-
Message:
System.ArgumentException : Invalid callback. Setup on method with 2 parameter(s) cannot invoke callback with different number of parameters (1).

我是单元测试的新手，但是到目前为止，我对GET和POST请求的单元测试一直很好。这是我在内部调用的哈希函数吗？
正在运行的控制器代码- [AllowAnonymous] [HttpPost（）] 公共异步任务AddMovie（MovieForDetailedDto movieForDetailedDto） { 如果（等待_repo.MovieExists（movieForDetailedDto.ATitle）） return BadRequest（“电影已经存在”）;
else if(!ModelState.IsValid || movieForDetailedDto.ATitle == null || movieForDetailedDto.APrice == null || movieForDetailedDto.AMovieDescription ==null)
{
return BadRequest("movie details not valid");
}
var movietoCreate = _mapper.Map<TblMovie>(movieForDetailedDto);
var createdMovie = await _repo.AddMovie(movietoCreate);
return Ok(createdMovie);
}
适用于上述控制器的测试-
[Test]
public async Task GivenAValidMovie_WhenIPostANewMovie_ThenItReturnsOkWithResponse()
{
_mockMovieRepository = new Mock<IMovieRepository>();
_mockMovieMapper = new Mock<IMapper>();

.ReturnsAsync((TblMovie movie) => movie);
_moviesController = new MoviesController(_mockMovieRepository.Object,_mockMovieMapper.Object);
var tblMovie = await _moviesController.AddMovie(new MovieForDetailedDto
{
AMovieId = 55,AWideImage = "https://github.com/tushar23091998/MovieRentalApp-FrontEnd/blob/master/src/app/images/bighero6.jpg?raw=true"
});
var okResult = tblMovie as OkObjectResult;
Assert.AreEqual(200,okResult.StatusCode);
Assert.NotNull(okResult);
Assert.IsAssignableFrom<OkObjectResult>(tblMovie);
var result = ((OkObjectResult)tblMovie).Value;
Assert.NotNull(result);
Assert.AreEqual(expectedMovie,result);
Assert.IsAssignableFrom<TblMovie>(result);
}
感谢您的宝贵时间。如果答案太明显，则表示歉意。
解决方法
<div id="page">
<div class="container">This is a test</div>
</div>只有一个参数。应该是
.ReturnsAsync((TblUser user) =>
