c# - 如何在 dotnet core 测试项目中使用用户 secret

Question

我想将集成测试的数据库连接字符串存储为用户 secret 。我的project.json 如下所示:

{
  ...

  "dependencies": {
    ...
    "Microsoft.Extensions.Configuration.UserSecrets": "1.1.0"        
  },

  "tools": {
    "Microsoft.Extensions.SecretManager.Tools": "1.1.0-preview4-final"
  },

  "userSecretsId": "dc5b4f9c-8b0e-4b99-9813-c86ce80c39e6"
}

我已将以下内容添加到测试类的构造函数中:

IConfigurationBuilder configurationBuilder = new ConfigurationBuilder()
    .AddJsonFile("appsettings.json")
    .AddUserSecrets();

但是，当我运行测试时，遇到该行时会引发以下异常:

An exception of type 'System.InvalidOperationException' occurred in Microsoft.Extensions.Configuration.UserSecrets.dll but was not handled in user code

Additional information: Could not find 'UserSecretsIdAttribute' on assembly 'dotnet-test-nunit, Version=3.4.0.0, Culture=neutral, PublicKeyToken=null'.

我是否错过了某些内容或者我想要的内容不受支持？

请参阅 https://patrickhuber.github.io/2017/07/26/avoid-secrets-in-dot-net-core-tests.html 中的说明，特别是在InitialiseTest中添加

// the type specified here is just so the secrets library can 
            // find the UserSecretId we added in the csproj file
            var builder = new ConfigurationBuilder()
                .AddUserSecrets<HttpClientTests>();

            Configuration = builder.Build()

但是请注意，它不允许在构建服务器上运行测试
