5 October, 2014: I have released a new version of the ASP Mvc RouteTester, numbered 1.3.0, with builds for ASP MVC 5.2 and ASP MVC 5.1. More news and thoughts about the future are here.
MvcRouteTester is a .Net library to help unit testing ASP MVC route tables. It contains asserts for for both regular controllers and the Api controllers that are new in MVC 4.0. It is built in .Net 4.0 and ASP MVC 5.2 and some older versions.
It can be used with a simple or a fluent syntax, e.g either RouteAssert.HasRoute(routes, "/home/index"); or routes.ShouldMap("/home/index").To<HomeController>(x => x.Index());
To aid automated testing by allowing unit tests on routes. Without such a library, the only way to automate a test that your ASP MVC application responds to a certain route is to make an integration test which fires up the whole MVC application in a web server and issues a Http request to that URL. Integration tests are good too, but unit tests run faster, easier to configure, are less fragile and generally come earlier in the coding life-cycle, so there are good reasons to use unit tests as a first line of defence against route configuration errors.
MvcRouteTester throws an exception in order to fail a test on a route. This should work in any unit testing framework. However, if you want to integrate closer with NUnit or another unit testing framework, you can do this.
