Ruby on Rails

Below is what the console is reporting when I run the test.
As you can notice, the test raises one error: method any? on nil class (the instance variable @atp_tournaments of the code in my first post).
If I change this instance variable with its explicit value, the next error is of next method on next variable and so on.
