Which test hits which line

I'm not sure if this is the right place, but I'm looking for something like nebulab/reverse_coverage.

I need to know which tests hit a specific line.

My real life use case

I'm reading a large enterprise codebase with a lot of complex logic and a huge number of BDD tests. I stumble upon a mind-boggling piece of code which I don't know which business scenarios it is used for. I need to find a list of BDD tests that run through this code.

Running all tests in debug mode and put a breakpoint at the code may work. However, I need to do this multiple times, and I cannot re-run the whole test suite every time.
