C# ASP.NET MVC：我正在尝试编写一个测试来查看新用户注册是否成功

Question

我有一个带有基本 Register 页面的 ASP.NET MVC 应用程序。这是注册新用户的具体功能。

Register.cshtml.cs:

public async Task<IActionResult> OnPostAsync()
{
        var returnUrl = Url.Content("~/Home/PostRegister");

        if (ModelState.IsValid)
        {
            var user = new IdentityUser { UserName = Input.Email, Email = Input.Email };
            var result = await _userManager.CreateAsync(user, Input.Password);
            if (result.Succeeded)
            {
                _logger.LogInformation("User created a new account with password.");

                var code = await _userManager.GenerateEmailConfirmationTokenAsync(user);
                var callbackUrl = Url.Page(
                    "/Account/ConfirmEmail",
                    pageHandler: null,
                    values: new { userId = user.Id, code = code },
                    protocol: Request.Scheme);

                await _emailSender.SendEmailAsync(Input.Email, "Confirm your email",
                    $"Please confirm your account by <a href='{HtmlEncoder.Default.Encode(callbackUrl)}'>clicking here</a>.");

                await _signInManager.SignInAsync(user, isPersistent: false);
                return LocalRedirect(returnUrl);
            }

            foreach (var error in result.Errors)
            {
                ModelState.AddModelError(string.Empty, error.Description);
            }
        }

        // If we got this far, something failed, redisplay form
        return Page();
}

这是我在集成测试中为它编写的测试：

[Fact]
public async Task DoesRegisterSucceed()
{
        // Arrange
        var client = _factory.CreateClient(
            new WebApplicationFactoryClientOptions
            {
                AllowAutoRedirect = false
            });
        
        var postRequest = new HttpRequestMessage(HttpMethod.Post, "/Identity/Account/Register");
        var formModel = new Dictionary<string, string>
        {
            { "Email", "test@example.com" },
            { "Password", "pas3w0!rRd" },
            { "ConfirmPassword", "pas3w0!rRd" },
        };

        postRequest.Content = new FormUrlEncodedContent(formModel);
        var response = await client.SendAsync(postRequest);

        response.EnsureSuccessStatusCode();

        //var responseString = await response.Content.ReadAsStringAsync();
        Assert.Equal(HttpStatusCode.OK, response.StatusCode);
}

我在运行测试时遇到此错误。

Failed amaranth.Tests.AuthTests.Get_ClaimAdminIsReturnedForFirstRegistered [505 ms]
Error Message:
System.Net.Http.HttpRequestException : Response status code does not indicate success: 400 (Bad Request).

Stack Trace:

--- End of stack trace from previous location ---

如何进行此测试或编写确保注册成功的新测试？

更新
如果相关，这是我正在使用的 CustomWebApplicationFactory.cs 文件：

using System;
using System.Linq;
using Microsoft.AspNetCore.Hosting;
using Microsoft.AspNetCore.Mvc.Testing;
using Microsoft.EntityFrameworkCore;
using Microsoft.Extensions.DependencyInjection;
using Microsoft.Extensions.Logging;
using amaranth.Data;

namespace amaranth.Tests
{
    #region snippet1
    public class CustomWebApplicationFactory<TStartup>
        : WebApplicationFactory<TStartup> where TStartup: class
    {
        protected override void ConfigureWebHost(IWebHostBuilder builder)
        {
            builder.ConfigureServices(services =>
            {
                var descriptor = services.SingleOrDefault(
                    d => d.ServiceType ==
                        typeof(DbContextOptions<ApplicationDbContext>));

                services.Remove(descriptor);

                services.AddDbContext<ApplicationDbContext>(options =>
                {
                    options.UseInMemoryDatabase("InMemoryDbForTesting");
                });

                var sp = services.BuildServiceProvider();

                using (var scope = sp.CreateScope())
                {
                    var scopedServices = scope.ServiceProvider;
                    var db = scopedServices.GetRequiredService<ApplicationDbContext>();
                    var logger = scopedServices
                        .GetRequiredService<ILogger<CustomWebApplicationFactory<TStartup>>>();

                    db.Database.EnsureCreated();
                }
            });
        }
    }
    #endregion
}

测试失败，因为您没有在 POST 中包含防伪 cookie 和验证令牌，因此出现 400 状态代码。来自 this page in the docs:

Any POST request to the SUT must satisfy the antiforgery check that's automatically made by the app's data protection antiforgery system. In order to arrange for a test's POST request, the test app must:

Make a request for the page.

Parse the antiforgery cookie and request validation token from the response.

Make the POST request with the antiforgery cookie and request validation token in place.
