Accessing instance variables in rspec

I don't have any code as this is just a hypothetical question, but how would you go about accessing and manipulating instance variables in rspec?

For instance if you had a @counter variable in your initialize method inside of a class, how could you write a test saying that if @counter is a certain number, then a certain method should return true. And if it equals a different number, then that method should return false.

describe Foo do
  context 'When counter is even' do
    let( :foo ){ Foo.new(4) }

    specify '#even?' do
      expect( foo.even? ).to be_true
    end
  end
end

According to your question, @counter is set in the initialize method. So the #even? method would check @counter.
