Can i get help with issues from github here?

I'm currently trying to contribute in a repo in GitHub and help with some of its issues , i have some few bug issues assigned to me which are really giving me a hard time so i thought it will be best i get some help here in reddit community without getting ridiculed on like i have in some other programming community website.
For reference I'm trying to solve the following issue in opentelemetry, it requires adding a new runtime/test package and adding an integration testing to it. I'm a complete novice to Go language so i don't know much about it but i do really want to learn, my question is; in which directory should theruntime/test package be added and how can the integration testing be added to it .
Thanks
