Arduino CI failing without clear error

[midasgossye]

Hey guys,

I just tried using the Arduino CI action on an Arduino library I wrote (github.com/Whaddadraft/VMA430_GPS_Module), but it keeps failing...
I can't really find the error in the logfile, but maybe that's purely because of my inexperience and/or incompetence...

Any help would be greatly appreciated!
I added the log file on the action step that keeps failing below, together with the used yml config file:

name: Arduino_CI

  arduino_ci:

    steps:

          #

          # Not all libraries include examples or unit tests.  The default
          #  behavior of arduino_ci is to assume that "if the files don't
          #  exist, then they were not MEANT to exist".  In other words,
          #  if you were to accidentally delete all your tests or example
          #  sketches, then the CI runner would by default assume that was
          #  intended and return a passing result.

          # installation commands should be placed in a shell script (that
          # will be executed by /bin/sh) stored in your library.
          #
          # Then, set this variable to the path to that file (relative to

Alright, I should have read the closed issues before I wrote this, sorry...
In #17 and #18 it was mentioned that the example configuration incorrectly shows that you can set the EXPECT_UNITTESTS to false. I simply deleted this variable altoghether in my yaml file and everything started working properly!

Below you can find the fixed config file I used in the end:

Hi @midasgossye -

I'm sorry for the confusion -- as you can see, I confused myself for a bit there with the way those environment variables are converted to boolean 🤦

But it looks like I haven't properly updated the project README about that mistake, so I will take care of that. Thanks for letting me know!

[midasgossye]

No worries, glad I could sort of help out 😅
I managed to test it out a bit today and I'm really impressed with how well it works (once I managed to set everything up).
Thanks for providing this awesome CI tool!

[ianfixes]

That's really nice of you to say! Please don't hesitate to open issues for other stuff that you run across. Documentation is the hardest thing for me to write, since I don't have a way to replicate being a first time user of the project
