Getting the ContentRootPath or getting IHostingEnvironment in a xunit context for .NET core

Question

I'm creating xunit tests for .NET core (net46 framework) and I'm having a problem getting the root path of the application, so I can locate things such as appsettings.json.

Can someone please explain how I can achieve one of the following:

• Get an instance of IHostingEnvironment

• Retrieve the absolute path of the .NET project containing the xunit test, so I can implement IHostingEnvironment myself.

It might be a very simple problem, I just can't seem to find a good solution.

Answer 1

As far as I remember injecting IHostingEnvironment in an XUnit test is not possible.

This is not ideal, but you could do something like this (ex: SetBasePath):

var configuration = new ConfigurationBuilder()
        .SetBasePath(Directory.GetCurrentDirectory())
        .AddJsonFile("remoteDeploymentConfig.json")
        .AddUserSecrets()
        .AddEnvironmentVariables()
        .Build();

This solution works because if you were to do dotnet test you need to do it from within the project directory itself as the test here corresponds to the xunit package of that project.
