Resharper with NUnit does not find local files

This is one of the problems we encounter ever so often but do not take the time to document it.

Say you have some test files in your project and have set their properties to Content and Copy Always.  You are using our favorite Resharper to run your unit tests using the NUnit test runner.  When you attempt to execute this test, you get an error as follows:

 Could not find a part of the path 'C:\Users\knji\AppData\Local\JetBrains\Installations\ReSharperPlatformVs15_427a36eb\TestFiles\PEs\notification.xml'.
 at System.IO.__Error.WinIOError(Int32 errorCode, String maybeFullPath)
 at System.IO.FileStream.Init(String path, FileMode mode, FileAccess access, Int32 rights, Boolean useRights, FileShare share, Int32 bufferSize, FileOptions

When you continue digging, you do realize that your files are indeed present in the bin/Debug folder of your application but Resharper just will not find it. Possible solutions:
1. Turn off Resharper shadow copying. This did not work for us.
2. Instruct your test to explicitly use the current working directory from the TestContext. This worked for us. So here’s the fix. Instead of doing this:

var file = File.ReadAllLines(@"my-relative-folder/some-cool-date.xml");

do this

var file = File.ReadAllLines(@TestContext.CurrentContext.TestDirectory + /"my-relative-folder/some-cool-date.xml");

Happy Coding.
