我嘗試為我的 API 控制器方法創(chuàng)建測(cè)試。簡(jiǎn)單來(lái)說(shuō)，我寫了add方法。 [HttpPost] [AllowAnonymous] public async Task<IActionResult> AddAsync([FromBody]BaseUserDTO dto) { if (ModelState.IsValid) { return Ok(); } else { return ValidationProblem(); } }在 dto 模型中我有public class BaseUserDTO{ [Required(ErrorMessage = "This field should be filled in", AllowEmptyStrings = false)] [RegularExpression(@"(^[a-zA-Z0-9_ -]+$)", ErrorMessage = ("Use only Latin characters"))] public string FirstName { get; set; } [Required(ErrorMessage = "This field should be filled in", AllowEmptyStrings = false)] [RegularExpression(@"(^[a-zA-Z0-9_ -]+$)", ErrorMessage = ("Use only Latin characters"))] public string LastName { get; set; } }我寫了第一個(gè)嘗試測(cè)試數(shù)據(jù)注釋[Fact]public async Task UserValidationError() { //Arrange BaseUserDTO userDTO = new BaseUserDTO { FirstName = "222A@@@", LastName = "Test", Email = "Test@test.com", PhoneNumber = "(111)111-1111", Role = 0, Password = "1234567A", RetypePassword = "1234567A" }; UserController controller = new UserController(userServicesMock.Object, mapperMock.Object, loggerMock.Object); //Act IActionResult result = await controller.AddAsync(userDTO); //Assert Assert.IsType<BadRequestObjectResult>(result); }但模型狀態(tài)總是正確的，我不明白為什么會(huì)發(fā)生？？？我的第二次嘗試在啟動(dòng)時(shí)在 mongo 連接中獲取 NullReference startup（在正常情況下它工作良好（當(dāng)應(yīng)用程序工作時(shí)），由郵遞員檢查）[Fact]public async Task UserValidationError(string userState) { //Arrange BaseUserDTO userDTO = new BaseUserDTO { FirstName = "222A@@@", LastName = "Test", Email = "Test@test.com", PhoneNumber = "(111)111-1111", Role = 0, Password = "1234567A", RetypePassword = "1234567A" }; }通常如何創(chuàng)建單元測(cè)試來(lái)檢查DataAnnotation驗(yàn)證？或者如何正確檢查此驗(yàn)證？
