Testing dynamic libraries

[pseusys]

Good afternoon!
I'm really interesting in using mull in the following setup: I have a simple executable (that doesn't require being tested) and a several dynamic libraries (*.so files) that I would like to test. My first obvious try was using non-standard test suite tutorial, specifying the library file path (one by one) for the mull-runner instead of the executable, like this: mull-runner /path/to/first/dynamic/library.so --ide-reporter-show-killed --test-program=/path/to/executable, but it didn't work.
Could you give me any advice, is there a way to perform mutation testing of my dynamic libraries?..
