NLog and Unit Testing

I am using NLog for my logger. Everything works fine when logging when I run an .exe, or even debug through Visual Studio, NLog will still write to the file.

But, if I run an object that calls the logger through a Unit test, the file is created but it is empty. Is there an extra setting/rule I need to add to the config to have NLog write to files under unit tests?

I could mock NLog for this and not have log dumps, but I'd like to see if I can get this to work before I decide to just mock NLog. Even though this is only happening in unit tests and is working otherwise, here is my config and code for logging. I left out the filenames.

public static void Info(string app, string m)  => EngineLogger.Logger.Info($"{app} : {m}");

            xsi:type="File"
            layout="${date:format=yyyy-MM-dd HH\:mm\:ss} ${pad:padding=5:inner=${level:uppercase=true}} ${logger} ${message}"
            fileName="leftoutForQuestion"
            keepFileOpen="false"
            encoding="iso-8859-2" />

            fileName="leftOutForQuestion"
