project.yml and utils:gcov

[Christian Cortes]

Hello, 

I am currently developing a lot of unit tests for some drivers that have been created 

the way  chose to tackle this, was to create a subrepo strictly for unit testing. so it looks like this

driver/

|

|--- test/

|     |

|     |--- config.yml

|     |--- test_driver.c

|

|--- unit_testing

|     |

|     |---build/

|     |---support/

|     |---project.yml

|

|--- src/

|     |

|     |---CMakelists.txt

|     |---Kconfig

|     |---driver.c

|     |---driver.h

notice that project.yml is not at the Highest level it can be. this is where the problem begins. 

1. env on WSL2 running ubuntu and zsh 

      Ceedling:: 0.31.1
      Unity:: 2.5.4
      CMock:: 2.5.4
      CException:: 1.3.3

2. if i make a local copy at the highest level (ex. driver/project.yml) and just modify the path to the test/ and support/ and other directories. the command 

ceedling options:config gcov:all utils:gcov

works just fine and generates the html output as expected. 

3. here is the portion of the yml for gcov when moved to the highest level

# Add -gcov to the plugins list to make sure of the gcov plugin

# You will need to have gcov and gcovr both installed to make it work.

# For more information on these options, see docs in plugins/gcov

:gcov:

  :reports:

    - HtmlDetailed

  :gcovr:

    :html_medium_threshold: 75

    :html_high_threshold: 90

4. now if i leave the project.yml file the same ceedling command does not work and this is what my :gcovr: section looks like now 

# Add -gcov to the plugins list to make sure of the gcov plugin

# You will need to have gcov and gcovr both installed to make it work.

# For more information on these options, see docs in plugins/gcov

:gcov:

  :reports:

    - HtmlDetailed

  :gcovr:

    :html_medium_threshold: 75

    :html_high_threshold: 90

    :object_directory: "build/gcov/out"

    :report_root: "../src"

5. one thing to note is that if my command is just 

ceedling options:config gcov:all

then it build and tests the code just fine. it only breaks when i introduce utils:gcov and only when I have the project.yml in the subrepo

6. the errors i am getting are all similar to 

RuntimeError: GCOV produced the following errors processing /home/chcortes/FirmwareModules/driver/unit_testing/build/gcov/out/mock_gpio.gcda:
        Cannot open source file build/test/mocks/mock_gpio.c

        Cannot open source file build/test/mocks/mock_gpio.c

        (gcovr could not infer a working directory that resolved it.)

7. these files do exist and i can see them if i go there manually. and i do not get these errors when i move my project.yml file to the highest location. 

has anyone tried this before and figured out how to make it work? i really do not want to have so many project.yml files on the driver/ since the file is not specific to each driver. 

thanks, 

let me know if you need more information
