我是新手,正在使用asp.net core。我正在测试一个控制器,该控制器将视图呈现为字符串,然后利用evo pdf来渲染视图。
一切都正常工作,我也可以成功地使用postman进行测试。但是当我使用VS 2017测试资源管理器(Xunit)调试我的测试时,我的测试应用程序出错了。 在Razor引擎中搜索位置 错误发生在我的RenderViewToString方法中,因为我的razor视图引擎无法找到要呈现的视图。搜索视图的路径与预期相同。欢迎您提供任何指导。
//Unit Test Code
[Fact]
public async void GetPdf()
{
var response = await _client.PostAsJsonAsync<Common.DTO.Invoice>("/api/values/1", GetDummyData());
using (var file = System.IO.File.Create(@"c:\\Test" + DateTime.Now.ToString("yyyyyMMddHHmmss") + ".pdf"))
{
//create a new file to write to
await response.Content.CopyToAsync(file);
await file.FlushAsync(); // flush back to disk before disposing
}
}
//Render view to string service
public interface IViewRenderService
{
Task<string> RenderToStringAsync(string viewName, ViewDataDictionary viewData);
}
public class ViewRenderService : IViewRenderService

_serviceProvider = serviceProvider;
}
public async Task<string> RenderToStringAsync(string viewName, ViewDataDictionary viewData)
{
var httpContext = new DefaultHttpContext { RequestServices = _serviceProvider };
var actionContext = new ActionContext(httpContext, new RouteData(), new ActionDescriptor());
using (var sw = new StringWriter())
{
var viewResult = _razorViewEngine.FindView(actionContext, viewName, false);
