我有一个ASP.NET Core 2.2 Razor Pages Web App，我已经为跟踪the official guide编写了一些集成测试。
我可以使用dotnet test或Visual Studio内置的测试运行程序来使测试在本地运行。但是，在构建服务器（Azure DevOps Hosted 2017代理）上，测试将返回500错误。我认为它可能与Scott Hanselman's guide中所述的用户机密有关，但即使实施了他建议的某些修复程序（我认为我也不需要全部修复程序）后，我仍然遇到相同的错误：
builder.AddUserSecrets<Startup>();添加到了启动中。CustomWebApplicationFactory，将环境设置为“开发”-下面的代码将此环境称为“生产”，以再现故障。我也对this guide进行了理智检查，它更侧重于控制器，但是由于我在此阶段仅关心响应代码，因此可以达到我的目的。我已经下载了详细的日志，但对这些问题并没有任何了解。
我的代码如下：
CustomWebApplicationFactory：
using Microsoft.AspNetCore.Authentication.AzureAD.UI;
using Microsoft.AspNetCore.Authentication.OpenIdConnect;
using Microsoft.AspNetCore.Hosting;
using Microsoft.AspNetCore.Mvc.Testing;
using Microsoft.AspNetCore.TestHost;
using Microsoft.Extensions.DependencyInjection;
namespace WebPortal.Int.Tests
{
/// <summary>
/// Based on https://fullstackmark.com/post/20/painless-integration-testing-with-aspnet-core-web-api
/// </summary>
public class CustomWebApplicationFactory<TStartup> : WebApplicationFactory<Startup> where TStartup : class
{
public CustomWebApplicationFactory() { }
protected override void ConfigureWebHost(IWebHostBuilder builder)
{
builder
.ConfigureTestServices(
services =>
{
services.Configure(AzureADDefaults.OpenIdScheme, (System.Action<OpenIdConnectOptions>)(o =>
{
// CookieContainer doesn't allow cookies from other paths
o.CorrelationCookie.Path = "/";
o.NonceCookie.Path = "/";
}));
}
)
.UseEnvironment("Production")
.UseStartup<Startup>();
}
}
}
AuthenticationTests：
using Microsoft.AspNetCore.Mvc.Testing;
using System;
using System.Net.Http;
using System.Threading.Tasks;
using Xunit;
namespace WebPortal.Int.Tests
{
public class AuthenticationTests : IClassFixture<CustomWebApplicationFactory<Startup>>
{
private HttpClient _httpClient { get; }
public AuthenticationTests(CustomWebApplicationFactory<Startup> fixture)
{
WebApplicationFactoryClientOptions webAppFactoryClientOptions = new WebApplicationFactoryClientOptions
{
// Disallow redirect so that we can check the following: Status code is redirect and redirect url is login url
// As per https://docs.microsoft.com/en-us/aspnet/core/test/integration-tests?view=aspnetcore-2.2#test-a-secure-endpoint
AllowAutoRedirect = false
};
_httpClient = fixture.CreateClient(webAppFactoryClientOptions);
}
[Theory]
[InlineData("/")]
[InlineData("/Index")]
[InlineData("/Error")]
public async Task Get_PagesNotRequiringAuthenticationWithoutAuthentication_ReturnsSuccessCode(string url)
{
// Act
HttpResponseMessage response = await _httpClient.GetAsync(url);
// Assert
try
{
response.EnsureSuccessStatusCode();
}
catch (HttpRequestException ex)
{
Console.WriteLine(ex.Message, ex.InnerException.Message);
}
}
}
}

我不清楚我在哪里/为什么得到空引用，因为据我所知OpenIdConnectOptions配置是正确的（并且与AAD SSO兼容）。
答案 0 :(得分：4)
事实证明，这是因为我没有在创建的.Build()对象上调用ConfigurationBuilder，而是将值分配给了{{1 }}类。这也意味着我将代码移至将机密包含到Configuration构造函数中。
即使如此，我的机密仍然无法在构建计算机上访问（这很有意义，因为它们是stored per machine）。因此，我还必须在构建管道中添加一个命令行任务-使用Startup命令添加测试所需的秘密。
答案 1 :(得分：0)
生产设置文件中是否可能缺少AzureAd配置部分？即appsettings.json与appsettings.Development.json
