That's normal. Remember that params exists because there is an http 
request issued. In your spec, you don't tell Rspec anything about any 
request. So you could create a mock for params. If I recall correctly 
you would have to do something like this:

describe ApplicationHelper do
   it "should be active if controller is same" do
    controller.params = {:controller => 'whatever_value'}
    tab_class('royalty_statement').should include('active')
