.net – 单元测试api控制器的示例代码

是否有示例代码显示单元测试继承自api控制器的控制器？
我正在尝试单元测试一个POST，但它是失败的。我相信我需要设置HttpControllerContext进行测试，但不知道如何
谢谢

解决方法

给定控制器代码有点像这样：

public class FooController : ApiController
{
    private IRepository<Foo> _fooRepository;

    public FooController(IRepository<Foo> fooRepository)
    {
        _fooRepository = fooRepository;
    }

    public HttpResponseMessage Post(Foo value)
    {
        HttpResponseMessage response;

        Foo returnValue = _fooRepository.Save(value);
        response = Request.CreateResponse<Foo>(HttpStatusCode.Created,returnValue,this.Configuration);
        response.Headers.Location = "http://server.com/foos/1";

        return response;
    }
}

单元测试会看起来像这样(NUnit和RhinoMock)

Foo dto = new Foo() { 
            Id = -1,Name = "Hiya" 
        };

        IRepository<Foo> fooRepository = MockRepository.GenerateMock<IRepository<Foo>>();
        fooRepository.Stub(x => x.Save(dto)).Return(new Foo() { Id = 1,Name = "Hiya" });

        FooController controller = new FooController(fooRepository);

        controller.Request = new HttpRequestMessage(HttpMethod.Post,"http://server.com/foos");
        //The line below was needed in WebApi RC as null config caused an issue after upgrade from Beta
        controller.Configuration = new System.Web.Http.HttpConfiguration(new System.Web.Http.HttpRouteCollection());

        var result = controller.Post(dto);

        Assert.AreEqual(HttpStatusCode.Created,result.StatusCode,"Expecting a 201 Message");

        var resultFoo = result.Content.ReadAsAsync<Foo>().Result;
        Assert.IsNotNull(resultFoo,"Response was empty!");
        Assert.AreEqual(1,resultFoo.Id,"Foo id should be set");
