ASP.NET Core运行两个TestServer进行集成测试

Posted 2021-03-28

我正在尝试为令牌管理API运行一些集成测试。 API还要求令牌颁发者API正在运行。

总之，我的集成测试需要同时运行IdentityServer4 Web / API和Management API。当我创建TestServer的两个实例时，看起来他们最终都得到了相同的BaseAddress（http://localhost）。

private readonly TestServer _identityTestServer;
private readonly TestServer _mgmtTestServer;
private readonly AppMgmtConfig _config;
private readonly AdminClient _adminClient;
private const string _certificatePassword = "test";

public AdminClientTests() : base(nameof(AdminClientTests))
{
    var connectionString = GetConnectionString();
    var dbSettings = new DbSettings(connectionString);

    Environment.SetEnvironmentVariable("IdentityServer4ConnString",
        dbSettings.IdentityServerConnectionString);
    Environment.SetEnvironmentVariable("CertificatePassword", _certificatePassword);

    _identityTestServer = new TestServer(new WebHostBuilder()
        .UseStartup<USBIdentityServer.Startup>()
        .UseEnvironment("IntegrationTest"));
    USBIdentityServer.Program.InitializeDatabase(_identityTestServer.Host);

    _mgmtTestServer = new TestServer(new WebHostBuilder()
        .UseStartup<IdentityServer4.Management.Startup>()
        .UseEnvironment("IntegrationTest"));

    _config = GetConfig();
    _adminClient = new AdminClient(_config);
}

注意：我已经尝试过的事情：

• 添加.UseUrls("http://localhost:5001")以查看TestServer是否将在该端口上运行。
• 添加serverName.BaseAddress = new Uri("http://localhost:5001");以查看TestServer是否将在该端口上运行。

这些似乎都没有影响它。

答案

我知道这是一个老问题，但我遇到了同样的问题。我认为诀窍是将你从“服务器1”获得的HttpClient注入“服务器2”。

示例（.NET Core）：

//Start and configure server 1.
IWebHostBuilder server1 = new WebHostBuilder()
 .UseStartup < Project1.Startup > ()
 .UseKestrel(options => options.Listen(IPAddress.Any, 80))
 .UseConfiguration(new ConfigurationBuilder()
  .AddJsonFile("appsettings_server1.json")
  .Build()
 );

TestServer testServer1 = new TestServer(server1);

//Get HttpClient that's able to connect to server 1.
HttpClient client1 = server1.CreateClient();

IWebHostBuilder _server2 = new WebHostBuilder()
 .UseStartup < Project2.Startup > ()
 .ConfigureTestServices(
  services => {
   //Inject HttpClient that's able to connect to server 1.
   services.AddSingleton(typeof(HttpClient), client1);
  })
 .UseKestrel(options => options.Listen(IPAddress.Any, 81))
 .UseConfiguration(new ConfigurationBuilder()
  .AddJsonFile("appsettings_server2.json")
  .Build()
 );

TestServer testServer2 = new TestServer(server2);
