Hello, it was previously failing a test because I removed some unused script(etc/scripts/irc-notify.py )

Error Message:

src\compiledcode\dwarf3.py:107: TypeError
==================== 6 failed, 142 passed in 19.59 seconds ====================
Command exited with code 1
python etc/scripts/irc-notify.py aboutcode [{project_name}:{branch}] {short_commit}: "{message}" ({author}) {color_red}Failed,Details: {build_url},Commit: {commit_url}
python: can't open file 'etc/scripts/irc-notify.py': [Errno 2] No such file or directory
Command exited with code 2

So I removed test from appveyor.yml.
Could you please confirm that this is acceptable?
or should I delete the entire file - appveyor.yml

Are you sure that #6 (comment) is about this repo?

You cannot remove the tests run... this would be a bit like hurting yourself with a knife intentionally.
Instead only remove the on_success and on_failure block below

Thank you, I got it; it was my fault.

Ignore this. I thought this was for scancode-toolkit

All good except for a nitpicking for a missing trailing empty line
