The process of finding and correcting errors in the program code is called ?

Writing a program rarely produces perfectly working code on the first attempt. The process of locating faults, known as bugs, in the source code and fixing them so the program behaves as intended is called debugging.

Testing is related but distinct: testing is the act of running the program against various inputs to discover whether errors exist, while debugging is the follow-up work of tracing those errors back to their exact location in the code and correcting them. Editing simply means changing text in a file and coding means writing the original program instructions, neither of which specifically refers to locating and fixing faults.

Keep the terms separate: testing reveals that something is wrong, and debugging is the process of finding out why and putting it right.
