First test suite failing with allure-rspec - ruby

Question

I'm working on integrating allure into my tests but have come across a problem with the first test suite failing and returning a undefined method `find_element' for nil:NilClass error with every test in the suite. The tests run as expected when I'm not using allure and the same thing happens regardless of what suite is run.
I've had a look into it and it seems the before and after hooks in my spec helper aren't being used in the failed tests. Any ideas what could be causing this?

#Start the Phantom-js driver before running any headless tests
case ENV['browser']
when 'headless'
## Run in command line before a headless test: phantomjs --webdriver=8001
system('start cmd /k phantomjs --webdriver=8001')
sleep 3
end
end
c.before(:each) do
#Find the browser to the used and set the driver to the appropriate one
