calendar_helper | Calendar-generating plugin for Ruby

I have a problem with rails. What I'm doing is creating a basic calendar, the creation logic goes in the folder /lib/, I invite it with a helper, called calendar_helper.rb, and this I call from the application view, passing the respective parameters. I also get the date data through the corresponding driver I have the following

/lib/calendar.rb

I have a conftest file to handle the setup and tear down of selenium drivers when running tests in pytest. I'm trying to add in a command line option to determine if I run the local built in selenium and web drivers or a remote selenium server and drivers etc...

I've added a commandline option called "runenv" and I'm trying to obtain the string value from this entered through command line to determine if the system should run local or remote webdriver configuration. This allows testers to develop on their own machines locally, but also means we can script the tests to run on the remote machine as part of a build pipeline.

The issue I have is that my parser.addoption shown in the below file is not processed. It doesn't seem return a value (whether it's the default or the value passed through command line) that I can use.

My conftest.py file is as follows (*note the url and remote IP are just samples to cover company privacy)
