HttpRequest および HttpResponse オブジェクトをモックする MsTest および Moq を使用した単体テスト クラスの例を次に示します。(.NET 4.0、ASP.NET MVC 3.0)
コントローラ アクションは、リクエストから値を取得し、レスポンス オブジェクトに http ヘッダーを設定します。他の http コンテキスト オブジェクトも同様の方法でモックアップできます
[TestClass]
public class MyControllerTest
{
protected Mock<HttpContextBase> HttpContextBaseMock;
protected Mock<HttpRequestBase> HttpRequestMock;
protected Mock<HttpResponseBase> HttpResponseMock;
[TestInitialize]
public void TestInitialize()
{
HttpContextBaseMock = new Mock<HttpContextBase>();
HttpRequestMock = new Mock<HttpRequestBase>();
HttpResponseMock = new Mock<HttpResponseBase>();
HttpContextBaseMock.SetupGet(x => x.Request).Returns(HttpRequestMock.Object);
HttpContextBaseMock.SetupGet(x => x.Response).Returns(HttpResponseMock.Object);
}
protected MyController SetupController()
{
var routes = new RouteCollection();
var controller = new MyController();
controller.ControllerContext = new ControllerContext(HttpContextBaseMock.Object, new RouteData(), controller);
controller.Url = new UrlHelper(new RequestContext(HttpContextBaseMock.Object, new RouteData()), routes);
return controller;
}
[TestMethod]
public void IndexTest()
{
HttpRequestMock.Setup(x => x["x"]).Returns("1");
HttpResponseMock.Setup(x => x.AddHeader("name", "value"));
var controller = SetupController();
var result = controller.Index();
Assert.AreEqual("1", result.Content);
HttpRequestMock.VerifyAll();
HttpResponseMock.VerifyAll();
}
}
public class MyController : Controller
{
public ContentResult Index()
{
var x = Request["x"];
Response.AddHeader("name", "value");
return Content(x);
}
}
