Testing code with HostingEnvironment.MapPath

[Sebastian Caballero]

I have to test a service using NUnit with this code:

var fileMap = new ExeConfigurationFileMap(); 
fileMap.ExeConfigFilename =   HostingEnvironment.MapPath("~/Modules/Proy.Notification/Web.config");
_configuration = ConfigurationManager.OpenMappedExeConfiguration(fileMap, ConfigurationUserLevel.None);

The problem is that HostingEnvironment.MapPath is returning null. Is there any way to mock my config or make it point to the right folder?

BTW: I can't change the code I'm testing.

Thanks!

I'm not a web developer, so someone else will have to give a definitive answer.

That said, the HostingEnvironment class represents the application
environment under which your ASP.Net application is running. When you
are running NUnit, you are not running under such an environment, so
you will have to find some way to simulate it. Most likely, for this
call, you will need something in the config.
