当斯科特格思里
first blogged on Razor时,他写道
The new view engine implementation will support the ability to unit test views (without requiring a controller or web-server,and can be hosted in any unit test project – no special app-domain required).
但是,我找不到关于剃刀可测试性的其他声明(或示例).
有指向使用CodelanguageServie或RazorGenerator或some self-made renderer – 非我称之为“按设计”.
目前是否可以通过简单的方式对剃刀视图进行单元测试？ (在asp.net mvc应用程序中,即.即NancyFx在其nancy.testing-package中带来了可测试性.)
(目前我不在乎if views should be tested or not.)
我知道有loads of questions like this one,但大多数都相当古老……
解决方法
我认为您可以对任何Razor视图进行单元测试,如下所示：
ViewResult v = View("~/Views/Home/Index.cshtml");
if (string.IsNullOrEmpty(v.ViewName))
v.ViewName = RouteData.GetrequiredString("action");
ViewEngineResult result = null;
StringBuilder sb = new StringBuilder();
StringWriter textwriter = new StringWriter(sb);
HtmlTextWriter htmlwriter = new HtmlTextWriter(textwriter);
if (v.View == null)
{
result = new ViewEngineResult(new RazorView(ControllerContext,"~/Views/Home/Index.cshtml",null,false,null),new RazorViewEngine());
v.View = result.View;
}
ViewContext viewContext = new ViewContext(ControllerContext,v.View,ViewData,TempData,htmlwriter);
v.View.Render(viewContext,htmlwriter);
string html = sb.ToString();
在此之后,您可以解析html以检查具有规范的内容.
