Debugging an existing project which is already compiled in codeblocks in Ubuntu

[ankush]

I have a big c/c++ project which is already built & already has an executable file. The project has some unit test files there which need to be debugged. In VS code we have launch.json file where we can give a test case name with args if any & it works. I am trying to get this info on how to setup Code blocks but couldn't find it. I believe there is already supported just am not able to figure it out. Any pointers would be helpful.
