测试的ASP.NET Web API POST和GET无参数与WebApiContrib.Testing路线 [英] Testing ASP.NET Web API POST and Parameterless GET Routes with WebApiContrib.Testing
问题描述
我想设置成使用WebApiContrib.Testing库的一些路线测试。我的GET测试（像这样），做工精细...
I am trying to set up some route tests using the WebApiContrib.Testing library. My get tests (like this) work fine...
[Test]
[Category("Auth Api Tests")]
public void TheAuthControllerAcceptsASingleItemGetRouteWithAHashString()
{
"~/auth/sjkfhiuehfkshjksdfh".ShouldMapTo<AuthController>(c => c.Get("sjkfhiuehfkshjksdfh"));
}
我宁愿失去了对测试后 - 我现在有哪些失败，出现NotImplementedException以下...
I am rather lost on the post test - I currently have the following which fails with a NotImplementedException...
[Test]
[Category("Auth Api Tests")]
public void TheAuthControllerAcceptsAPost()
{
"~/auth".ShouldMapTo<AuthController>(c => c.Post(new AuthenticationCredentialsModel()), "POST");
}
这里的建立和拆除的完整性......
Here's the setup and teardown for completeness...
[SetUp]
public void SetUpTest()
{
RouteConfig.RegisterRoutes(RouteTable.Routes);
WebApiConfig.Register(GlobalConfiguration.Configuration);
}
[TearDown]
public void TearDownTest()
{
RouteTable.Routes.Clear();
GlobalConfiguration.Configuration.Routes.Clear();
}
我想测试路线是默认POST路线，它映射到这个方法调用...
The route I am trying to test is the default POST route, which maps to this method call...
[AllowAnonymous]
public HttpResponseMessage Post([FromBody] AuthenticationCredentialsModel model)
{ *** Some code here that doesn't really matter *** }
我也越来越对这个测试，测试不带参数的标准GET路线返回的所有项目......失败
I am also getting a failure on this test that tests the standard GET route without parameters returns all of the items...
[Test]
[Category("VersionInfo Api Tests")]
public void TheVersionInfoControllerAcceptsAMultipleItemGetRouteForAllItems()
{
"~/versioninfo".ShouldMapTo<VersionInfoController>(c => c.Get());
}
这是检验这种方法...
Which is testing this method...
public HttpResponseMessage Get()
{ *** Some code here that doesn't really matter *** }
本库推荐的几篇文章我读了，但现在我不知道如果我做错了什么，或者如果它只是非常有限的，我最好我自己的滚动。
This library was recommended by several articles I read, but I'm not sure now if I'm doing something wrong or if it's just quite limited and I'm better off rolling my own.
推荐答案
我解决了这个问题到底写我自己的，放在这里的另一个问题由whyleee阅读帖子之后 - <一个href=\"http://stackoverflow.com/questions/11851558/testing-route-configuration-in-asp-net-webapi/18531364#18531364\">Testing在ASP.NET的WebAPI 路由配置（WebApiContrib.Testing似乎并没有为我工作）
I fixed this in the end by writing my own, after reading a post by whyleee on another question here - Testing route configuration in ASP.NET WebApi (WebApiContrib.Testing didn't seem to work for me)
我合并他的职位与一些我喜欢的语法从WebApiContrib.Testing库中生成以下辅助类的元素。
I merged his post with some of the elements I liked syntactically from the WebApiContrib.Testing library to generate the following helper class.
这让我写很轻的测试，像这样...
This allows me to write really lightweight tests like this...
[Test]
[Category("Auth Api Tests")]
public void TheAuthControllerAcceptsASingleItemGetRouteWithAHashString()
{
"http://api.siansplan.com/auth/sjkfhiuehfkshjksdfh".ShouldMapTo<AuthController>("Get", "hash");
}
[Test]
[Category("Auth Api Tests")]
public void TheAuthControllerAcceptsAPost()
{
"http://api.siansplan.com/auth".ShouldMapTo<AuthController>("Post", HttpMethod.Post);
}
helper类看起来是这样的...
The helper class looks like this...

foreach (var param in actionMapping.GetParameters())
