HI there

I was wondering if there is a better way of testing that a view has rendered in MVC.

I was thinking perhaps I should render the view to a string but perhaps there are simpler methods?

Basically what I want to know if that the view for a given action has rendered without errors I m already testing the view model but I want to see that rendering the view giving a correct ViewData.Model works

Use the MvcContrib TestHelpers library to perform assertions that a particular view is being returned from your action:

var sampleController = new SampleController();
sampleController.New().AssertViewRendered().ForView("New").WithViewData<SomeModel>();

To make assertions to ensure you are returning the correct data to the view, pull the model from the ActionResult:

var result = (ViewResult)sampleController.New();
((SomeModel)result.ViewData.Model).SomeProperty.ShouldNotBeNull();

This is as far as your unit testing should go.

For end-to-end automated functional/GUI testing you might want to think about using a tool like Selenium.

You can enable views compilation for your project. In this way the project won't compile unless you fix the issues. Edit this line in the .csproj file:

<MvcBuildViews>false</MvcBuildViews> by using true instead of false

I you can also use ELMAH (install it view NuGet) and you can receive detailed errors by email (including YSOD).
