Rspec how to call ENV variable before driver configuration - selenium-webdriver

Question

I am writing UI tests on a new feature. This feature is iframed in, and appears in all browser configuration except for incognito with third party cookies blocked. I have created a new browser settings option that I can call to run the test suite locally "BROWSER=iframe_present rspec --tag service:test_tag" or the test itself "BROWSER=iframe_present rspec spec/service_folder/example_test_spec.rb".
My goal is to set it up so that only this test file; or service tag ("test_tag") run with the specific browser configuration when automatically through a travis configuration (which I can test locally by running "BROWSER=headless rspec spec/service_folder/example_test_spec.rb").
I've tried to call the 'iframe_present' browser configuration from the test file in a few different ways, but each one hits the byebug I have in the final 'else' browser condition. Perhaps I need to use the ci.travis.sh file? Seems to deal with picking the browser config.

Answer 1

If I'm understanding correctly, I believe you need the following in your test:
before do
allow(ENV).to receive(:[])
.with("BROWSER").and_return("iframe_present")
end
