this code should demonstrate the basics of a post test. Assumes you have a repository injected into the controller. I am using MVC 4 RC not Beta here if you are using Beta the Request.CreateResponse(... is a little different so give me a shout...

Given controller code a little like this:

<pre><code>public class FooController : ApiController
{
 private IRepository&lt;Foo&gt; _fooRepository;

 public FooController(IRepository&lt;Foo&gt; fooRepository)
 {
 _fooRepository = fooRepository;
 }

 public HttpResponseMessage Post(Foo value)
 {
 HttpResponseMessage response;

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

 return response;
 }
}
</code></pre>

The unit test would look a little like this (NUnit and RhinoMock)

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

 IRepository&lt;Foo&gt; fooRepository = MockRepository.GenerateMock&lt;IRepository&lt;Foo&gt;&gt;();
 fooRepository.Stub(x =&gt; 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&lt;Foo&gt;().Result;
 Assert.IsNotNull(resultFoo, "Response was empty!");
 Assert.AreEqual(1, resultFoo.Id, "Foo id should be set");
</code></pre>

I've created a general solution for calling some action and getting <code>HttpResponseMessage</code> as <code>Dictionary</code> which is very convenient for usage.

First some extension for the <code>dictionary</code>:

<pre><code>public static class DictionaryExtensions
{
 public static void AddRange&lt;T, S&gt;(this Dictionary&lt;T, S&gt; source,
 Dictionary&lt;T, S&gt; collection) 
 {
 if (collection == null)
 {
 throw new NullReferenceException("Collection is null");
 }

 foreach (var item in collection)
 {
 source.Add(item.Key, item.Value);
 }
 }
}
</code></pre>

Now request creating part:

<pre><code>public class RequestCreator
{
 protected static void FirstPart(ApiController controller,
 HttpMethod method,String actionUrl)
 {
 // Creating basic request message with message type and requesting 
 // url example : 'http://www.someHostName/UrlPath/'
 controller.Request = new HttpRequestMessage(method, actionUrl);

 // Adding configuration for request
 controller.Request.Properties.
 Add(HttpPropertyKeys.HttpConfigurationKey,new HttpConfiguration()); 
 }

 protected static Dictionary&lt;String, Object&gt; SecondPart
 (HttpResponseMessage response)
 {
 // Adding basic response content to dictionary
 var resultCollection = new Dictionary&lt;String, Object&gt;
 {
 {"StatusCode",response.StatusCode},
 {"Headers",response.Headers},
 {"Version",response.Version},
 {"RequestMessage",response.RequestMessage},
 {"ReasonPhrase",response.ReasonPhrase},
 {"IsSuccessStatusCode",response.IsSuccessStatusCode}
 };

 var responseContent = response.Content;
 // If response has content then parsing it and 
 // getting content properties
 if (null != responseContent)
 {
 var resultMessageString = response.Content.
 ReadAsStringAsync().Result;
 resultCollection.AddRange((new JavaScriptSerializer()).
 DeserializeObject(resultMessageString) 
 as Dictionary&lt;String, Object&gt;);
 }


 return resultCollection;
 } 
}
</code></pre>

And finally response message to dictionary converter <code>class</code>:

<pre><code>public class HttpResponseModelGetter : RequestCreator
{
 public Dictionary&lt;String, Object&gt;
 GetActionResponse(ApiController controller,HttpMethod method,
 String actionUrl,Func&lt;HttpResponseMessage&gt; callBack)
 {
 FirstPart(controller, method, actionUrl);
 var response = callBack();
 return SecondPart(response);
 }
}

public class HttpResponseModelGetter&lt;T&gt; : RequestCreator
{
 public Dictionary&lt;String, Object&gt; 
 GetActionResponse(ApiController controller,HttpMethod method,
 String actionUrl,Func&lt;T,HttpResponseMessage&gt; callBack,T param) 
 {
 FirstPart(controller, method, actionUrl);
 var response = callBack(param);
 return SecondPart(response);
 }
}

public class HttpResponseModelGetter&lt;T1,T2&gt; : RequestCreator
{
 public Dictionary&lt;String, Object&gt; 
 GetActionResponse(ApiController controller,HttpMethod method, 
 String actionUrl,Func&lt;T1,T2,HttpResponseMessage&gt; callBack,
 T1 param1,T2 param2)


 {
 FirstPart(controller, method, actionUrl);
 var response = callBack(param1,param2);
 return SecondPart(response);
 }
} 
//and so on...
</code></pre>

and usage :

<pre><code>var responseGetter = new HttpResponseModelGetter();
var result = responseGetter.GetActionResponse(controller,HttpMethod.Get,
 "http://localhost/Project/api/MyControllerApi/SomeApiMethod",
 controller.SomeApiMethod);

Boolean isComplete = Boolean.Parse(result["isComplete"].ToString());
</code></pre>

Is there an sample code that shows unit testing a controller that inherits from the api controller?
I am trying to unit test a POST but it is failing. I believe I need to set up the HttpControllerContext for testing but don't know how
Thanks

Sample code for unit testing api controllers

单元测试

是否有示例代码显示了对继承自api控制器的控制器进行单元测试？我正在尝试对POST进行单元测试，但它失败了。我想我需要设置HttpControllerContext以进行测试，但不知道如何设置，谢谢
