Is there a way to create TestMethods on-the-fly for VS2017 Ent?

I have a C# application built over .NET 4.6.1 (VS2017).

I am now building a test environment and would like to include user base tests.

The user provide a folder of files, each one is a seperate user test i need to run against.

I would like to create a TestMethod for each file to run against my application within VS2017.

Is there a way to automate such task? or the only way is to write a script to create the TestClass implementing a uniqueTestMethod for each file
