例如我们在Web Api项目中有个Controller
public class SomeController : ApiController { public HttpResponseMessage Get() { // 一些操作 return Request.CreateResponse(HttpStatusCode.OK, someModel); } }
如果你在单元测试中直接调用 SomeController
的Get()方法,那么你将会收到一个Exception提示Request为Null。
因此我们需要在测试代码中构造一个Request,有两种方法
1、简单构造法
[TestMethod] public void UnitTestMethod() { // 环境准备部分 YourNameSpace.Controllers.SomeController controller = new SomeController(); // 下面两个语句是构造一个简单的请求报文 controller.Request = new HttpRequestMessage(); controller.Request.SetConfiguration(new HttpConfiguration()); var result = controller.Get(); // 断言 }
2、可控性更强的构造
[TestMethod] public void UnitTestMethod() { // 环境准备部分 YourNameSpace.Controllers.SomeController controller = new SomeController(); var config = new HttpConfiguration(); var request = new HttpRequestMessage(HttpMethod.Post, "YourUrl"); var route = config.Routes.MapHttpRoute("DefaultApi", "api/{controller}/{id}"); var routeData = new HttpRouteData(route, new HttpRouteValueDictionary { { "controller", "products" } }); controller.ControllerContext = new HttpControllerContext(config, routeData, request); controller.Request = request; controller.Request.Properties[HttpPropertyKeys.HttpConfigurationKey] = config; var result = controller.Get(); // 断言 }
然后就可以运行单元测试查看结果了。
