从TestServer测试asp.net 5 vnext中间件

Question

在owin中,可以使用TestServer在单元测试中测试web api(参见本博客).

这个功能是否适用于asp.net 5中间件？

更新:

根据下面的回答,我尝试使用TestServer,但是visual studio抱怨'名称空间名称'AspNet'在名称空间'Microsoft'中不存在(你......)

• 我使用Visual Studio 2015

• 在我的nuget来源(设置)我有(https://www.myget.org/F/aspnetmaster/)(我也试过https://www.myget.org/F/aspnetvnext/,但遇到了同样的问题)

• 这是我的project.json文件

  {
      "version": "1.0.0-*",
      "dependencies": {
          "Microsoft.AspNet.Http": "1.0.0-*",        
          "Microsoft.AspNet.TestHost":  "1.0.0-*",
          "Microsoft.AspNet.Hosting":  "1.0.0-*", 
          "Microsoft.AspNet.Testing" :  "1.0.0-*",
          "xunit": "2.1.0-beta1-*",
          "xunit.runner.aspnet": "2.1.0-beta1-*",
          "Moq": "4.2.1312.1622",
          "Shouldly": "2.4.0"
      },
      "commands": {
          "test": "xunit.runner.aspnet"
      },
      "frameworks" : {
          "aspnet50" : {
              "dependencies": {
              }
          }
      }
  }
  

Answer 1

它也可以在ASP.NET 5上使用:Microsoft.AspNet.TestHost.

这是一个例子.中间件:

public class DummyMiddleware
{
    private readonly RequestDelegate _next;

    public DummyMiddleware(RequestDelegate next)
    {
        _next = next;
    }

    public async Task Invoke(HttpContext context)
    {
        Console.WriteLine("DummyMiddleware");
        context.Response.ContentType = "text/html";
        context.Response.StatusCode = 200;

        await context.Response.WriteAsync("hello world");
    }
}

测试:

[Fact]
public async Task Should_give_200_Response()
{
    var server = TestServer.Create((app) => 
    {
        app.UseMiddleware<DummyMiddleware>();
    });

    using(server)
    {
        var response = await server.CreateClient().GetAsync("/");
        Assert.Equal(HttpStatusCode.OK, response.StatusCode);
    }
}
