view.render 메서드를 사용하여 MVC 뷰를 문자열로 변환하는 단위 테스트 메서드

Question

MVC 뷰를 문자열로 변환하고 테스트 메서드를 사용하여 문자열을 반환하는지 확인하는 메서드를 작성했습니다.

물론 웹에서도 작동하지만 NUnit에서 테스트를 실행하면 메서드가 View.Render를 호출 할 때 System.Web에 NullReferenceException이 throw됩니다.

렌더링 방법 코드 : 모의 컨트롤러 컨텍스트

public string RenderEmailBody<T>(string viewPath, T model, ControllerContext controllerContext, bool isParialView) 
{ 
    ViewEngineResult viewEngineResult = null; 
    if (isParialView == true) 
    { 
     viewEngineResult = ViewEngines.Engines.FindPartialView(controllerContext, viewPath); 
    } 
    else 
    {

    } 

    if (viewEngineResult == null) 
    { 
     throw new FileNotFoundException("Coukld not find view."); 
    } 

    var view = viewEngineResult.View; 
    controllerContext.Controller.ViewData.Model = model; 

    string result = null; 

    using (var sw = new StringWriter())

            controllerContext.Controller.ViewData, 
            controllerContext.Controller.TempData, 
            sw); 
     view.Render(ctx, sw); 
     result = sw.ToString(); 
    } 

    return result;

여기

는 스택 트레이스이고 및 HttpRuntime.AppDomainAppVirtualPathString int System.Web.VirtualP athString이 NULL입니다.

단위 테스트 용으로 설정할 수 있습니까?

미리 감사드립니다.

Answer 1

VirtualPathProvider를 구현해 보셨습니까? 이 같은

뭔가 :이 방법으로

///register our custom virtual path provider factory. 
      HostingEnvironment.RegisterVirtualPathProvider(new CustomVirtualPathProvider()); 

Global.asax에

에서 다음

public class CustomVirtualPathProvider : VirtualPathProvider 
    { 
     internal class CustomVirtualFile : ViewVirtualFile 
     { 
      public override bool IsDirectory 
      { 
       get 
       { 
        return base.IsDirectory; 
       } 
      } 
      public override string Name 
      { 
       get 
       { 
        return base.Name; 
       } 
      } 
      public override string ResourceKey 
      { 
       get 
       { 
        return base.ResourceKey; 
       } 
      } 
      public override System.IO.Stream Open() 
      { 
       return base.Open(); 
      } 
      public CustomVirtualFile(string path) 
       : base(path) 
      { 

      } 

     } 
     public override bool FileExists(string virtualPath) 
     { 
      return base.FileExists(virtualPath); 
     } 
     public override VirtualFile GetFile(string virtualPath) 
     { 
      return base.GetFile(virtualPath); 
     } 
     public override VirtualDirectory GetDirectory(string virtualDir) 
     { 
      return base.GetDirectory(virtualDir); 
     } 
     public override bool DirectoryExists(string virtualDir) 
     { 
      return base.DirectoryExists(virtualDir); 
     } 


    } 

, 당신은 어디에서 뷰를 렌더링 할 수 있습니다.
