I want to use ../ (parent directory) as search_paths. If I pass the command gcovr ../ in cli, it works fine (checked in verbose as well, it scans the ../ directory). However, if I use a configuration file and put search-path = ../ it doesn't work and instead scans the . directory. What should I put as the value for search-path?

Can you explain your directory layout?
The search path in the configuration file is treated as relative to the directory of the configuration file. If your file is in a sub directory it results in..

I have the Makefile, config file and other files needed for running unit tests in 'child' folder. The source files are one level above, aka 'parent' folder. I run make, executables and also gcovr cli from child folder, hence the command gcovr ../ works.

And the config file with the search paths is in the working directory?

Yes, the config file is in the working directory.

Can you post the start of the verbose outputs where the configuration is printed?

This is the gcovr.cfg file:

txt-branch = yes
filter = .*
exclude = mock
verbose = yes
search-path = ../

Not Github, this is Markdown syntax. Use always verbatim text blocks.

Can you add the command line and the working directory?

Pls note: I have changed directory names to safeguard some sensitive data just in case

This is when override the config file's search paths with cli. I guess the question is, how do I specify the parent directory as a relative path in the config file for the search-path?

Now I get the problem. The path ../ is split into ., . and /.
Which version are you using? In Version 5.2 there was a fix for this (#612)

I am using gcovr version 5.0

Edit: So the only solution is to upgrade to 5.2?
