This is not supposed to happen 🤯 you ought to mock the environment variable away. Unit test means to test a standalone unit 😘

Please add a newline at the end of the file since some tools don't execute the last line if it ends with EOF (end of file) instead of a newline \n.

Pleas write out command line options if you can. I have no fricking clue what -s is ❓

Interesting way to test this 😅 is there maybe an easier and more transparent way to possible test this? Like checking if something equals something without summing up and other tricks?

This is so beautiful and smart 💡 I'm proud of you 😘

You can make your life easier here and just put into the json payload what you extract in the end. This makes everything much much shorter.

Please remove this and mock the environment variable getter.

It is nice how you call the function here, but you only check that it does not error out basically. If you really want to know what was done inside, you need to mock the print or stdout and verify how the output message would look like with an assert.

You have two choices:
- Make the function an internal function by starting with an underscore
_ - Write a more complete docstring describing the function including the parameters and return value
A few unittests to start things off. Main focus is on how to work with Github secrets for the API key.
