Pluralsight RSpec the Right Way: Wrong Number of Arguments for expect(client.url).to eq

Question

I just started Pluralsights' RSpec the Right Way module. In trying to define @url = url, I noticed that it doesn't colorize as in the tutorial video, and received the following failure upon trying to get it to pass. I'm a complete rspec newb, so I need help in dissecting what went wrong here.

Thanks

Answer 1

I had the same problem with the rspec 2.8.0. and the newer version fixed it. As it says, Rspec 2.8.0, expect(something) causes ArgumentError: wrong number of arguments (1 for 0)
