.net – 单元测试api控制器的示例代码

这段代码应该展示后期测试的基础知识。假设您有一个注册到控制器的存储库。我正在使用MVC 4 RC不是测试版，如果你使用Beta的request.CreateResponse(…有一点不同，所以给我一个喊…

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(httpR_700_11845@ethod.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");
