Batch: get path without file name

Question

I hope it isn't a duplicate as I looked around and could not find an answer.

I have a batch script witch uses python coverage tool to execute tests and measure coverage.

the scripts traverse through all sub folders of a main unit tests folder and execute tests.

The thing is, I need to call coverage run command from the same folder where my tests files are so I need to first change the batch current directory to the directory of the current test, for each test.

How can it be done?

This is my current script

    @echo off

    for /r %%f in (Test_*.py) do (

        echo current test (full path) is %%f

        :: I need a way to change CD to the directory of %%f
        :: before running the test. the problem is that %%f contains the file 
        :: name so I cant just `cd %f%`

        coverage run -a "%%f"
    )
    coverage report > "coverage_results.txt" 
    coverage erase 
    pause

Thanks
