测试HttpResponse.StatusCode的结果

Question

我写了一个ErrorsController你可以想象的,有一些非常简单的方法可以在错误的情况下继续提供动态内容,例如500.

现在我要做的是测试在该方法中,HttpResponseBase.StatusCode在执行此方法时将其设置为给定数字,但由于某种原因,该StatusCode属性始终为0.这包括在设置后直接检查属性时.

调节器

public ViewResult NotFound()
{
    Response.StatusCode = (int)HttpStatusCode.NotFound;

    const string PageTitle = "404 Page Not Found";
    var viewModel = this.GetViewModel(PageTitle);

    return this.View(viewModel);
}

GetViewModel 除了在视图模型上设置属性之外什么也不做

测试

[SetUp]
public void Setup()
{
    this.httpContext = new Mock<HttpContextBase>();
    this.httpResponse = new Mock<HttpResponseBase>();

    this.httpContext.SetupGet(x => x.Response).Returns(this.httpResponse.Object);

    this.requestContext = new RequestContext(this.httpContext.Object, new RouteData());
    this.controller = new ErrorsController(this.contentRepository.Object);

    this.controllerContext = new Mock<ControllerContext>(this.requestContext, this.controller);
    this.controllerContext.SetupGet(x => x.HttpContext.Response).Returns(this.httpResponse.Object);
    this.controller.ControllerContext = this.controllerContext.Object;
}

[Test]
public void Should_ReturnCorrectStatusCode_ForNotFoundAction()
{
    this.controller.NotFound();
    this.httpResponse.VerifySet(x => x.StatusCode = (int)HttpStatusCode.NotFound); 
    Assert.AreEqual((int)HttpStatusCode.NotFound, this.httpResponse.StatusCode); 
}

我在哪里错了？

Answer 1

只需在设置阶段添加:

httpResponse.SetupAllProperties();

话虽这么说,你可能不需要这两个断言:

this.httpResponse.VerifySet(x => x.StatusCode = (int)HttpStatusCode.NotFound); 
Assert.AreEqual((int)HttpStatusCode.NotFound, this.httpResponse.StatusCode); 

第一个应该足以进行单元测试.
