Test Smell Tool Detect Test level file or Functional Level ?

[usmanshahid]

Hi Folks
My Thesis is based on test smells I need some help that Test Smell tool detect are based on Test level files (Test case file has many test cases) or Function Level files (Test case file contain different function to be tested) and I want's to know that Test smell Tool give results on the basis of ( single test case file that contain all result of test cases) or ( test case file give different results of different test cases ) ?

If test case file give results of different test cases, then which method are used to separate the different function from Test cases other wise it's time taking to remove test cases from every file and makes copies, every copies contain 1 test case.

My Thesis work is Test smell tools detect at functional Level.
