Question

我试图将集成测试添加到我的项目中，但我一直收到错误＆＃34;类型或命名空间名称＆＃39; Startup＆＃39;找不到＆＃34;在我的Tests.cs文件中。

我有两个project.json文件，一个在我的src项目中，另一个在我的测试项目中。

Src project.json看起来像这样：

{
"dependencies": {
"Microsoft.NETCore.App": {
  "version": "1.0.1",
  "type": "platform"
},
"Microsoft.EntityFrameworkCore.SqlServer": "1.0.0",
"Microsoft.EntityFrameworkCore.Tools": {
  "version": "1.0.0-preview2-final",
  "type": "build"
},

"Microsoft.Extensions.SecretManager.Tools": "1.0.0-preview2-final"},
"frameworks": {

]},
"scripts": {
"postpublish": [
  "dotnet publish-iis --publish-folder %publish:OutputPath% --framework %publish:FullTargetFramework%"
]},
"tooling": {
 "defaultNamespace": "api"}}

Test project.json看起来像这样：

{
"version": "1.0.0-*",
"buildOptions": {
"debugType": "portable"},
"dependencies": {
"System.Runtime.Serialization.Primitives": "4.1.1",
"xunit": "2.1.0",

"SrcService": {
  "target": "project"
},
"Microsoft.AspNetCore.TestHost": "1.0.0"},
"testRunner": "xunit",
"frameworks": {
"netcoreapp1.0": {
  "dependencies": {
    "Microsoft.NETCore.App": {
      "type": "platform",
      "version": "1.0.1"
    }
  },
  "imports": [
    "dotnet5.4",
    "portable-net45+win8"
  ]
}}}

My Tests.cs类看起来像这样：

using System;
using Xunit;
using Microsoft.AspNetCore.TestHost;
using System.Net.Http;
using Microsoft.AspNetCore.Hosting;


namespace Tests
{
public class Tests
{
    public TestServer server { get; }
    public HttpClient client { get; }

    public Tests(){
        var builder = new WebHostBuilder().UseStartup<Startup>();
        server = new TestServer(builder);
        client = server.CreateClient();
    }

[Fact]
public async void TestVisitRoot() {
    var response = await client.GetAsync("/");
    response.EnsureSuccessStatusCode();
}
}}

有谁知道我为什么会收到此错误？提前谢谢！

Answer 1

检查您namespace中的Startup.cs，该地址应与Program.cs中的相同。

Program.cs

using System;
using Microsoft.AspNetCore.Builder;
using Microsoft.AspNetCore.Hosting;
using Microsoft.AspNetCore.Http;


namespace dotnetcoretester  // <------- This
{
    class Program
    {
     ...

Startup.cs

using System;
using Microsoft.AspNetCore.Builder;
using Microsoft.AspNetCore.Hosting;
using Microsoft.AspNetCore.Http;
using Microsoft.Extensions.DependencyInjection;

namespace dotnetcoretester // <------ and This
{
  public class Startup
  {
    public void Configure(IApplicationBuilder app)
    ...

Answer 2

我在您的测试项目Project.json中看到了

"SrcService": {
   "target": "project"
}

这意味着你的Startup类就在这个项目中。要在Test.cs中识别，您只需添加using

即可

using [namespace the Startup class is in];

那应该是这个。

提示：如果您使用的是Visual Studio，那么当您遇到类似这样的问题时。只需点击它，然后按CTRL + .（或右键单击Quick action and refactoring与VS2015）

Answer 3

您可以添加

使用ConsoleApplication;

程序顶部的

。

类型或命名空间名称＆＃39; Startup＆＃39;无法找到
