Test coverage output

[samdion1994]

Hi @OlegKunitsyn,

Is it possible to get a report of the results of the Test coverage in an output ?
Like so to run in sonar.

Thanks!

First of all, let me forward you to Medium articles where I demonstrated a "modern" SDLC:

• Modern COBOL: Package Tutorial
• Modern COBOL: Microservice Tutorial

Integration of GCBLUnit that brings the concept of Test and Unit to the debugger (as well as output in JUnit format) is complicated by this - OlegKunitsyn/gnucobol-docker#2 (comment)

Back to your question. The debugger colors executed lines in VSCode when the coverage is enabled. Coverage data parsed by gcov-parse are available in run-time, so you could implement an export functionality and propose a Pull Request. It would not be the "Test coverage", but better than nothing.

Couldn't one create a simple task and execute `gcov ${filename}? there (test would be possible by opening the terminal and execute it there manually)?

Hi @GitMensch,

Noobie here but very interested in the value here and helping out. :)

But I don't get the whole "gcov" thing. I'd tried read online, but I can't seem to find anything. Maybe you can point me out where and how I can use it with gnuCobol.

I tried the following

C:\workspace>cobc -v
cobc (GnuCOBOL) 3.1.2.0
Built Jul 05 2021 22:53:56 Packaged Dec 23 2020 12:04:58 UTC
C version (MinGW) "6.3.0"

C:\workspace\cobol-check2>gcov -v
gcov (MinGW.org GCC-6.3.0-1) 6.3.0

Thanks :)

That seems like a side-note, something you may want to question at the GnuCOBOL discussion boards (it ends in "pass the correct coverage options to GCC via cobc, then run the program, then check the coverage).
As far as I've seen it this plugin adds the coverage compile options needed and then reads the coverage data via a js library to present it, but it's been a while since I've looked.
