Question5 2 pts Remove the,:disabled-true from the constructor collection in the spec/rubybasics3_spec.rb file. Don't forget to save your changes! Write code that will raise ArgumentError (one of Ruby's built-in exception types) if the ISBN number is the empty string or if the price is less than or equal to zero. Include the proper getters and setters for these attributes. Run rspec in the terminal window to test. Once everything is passing, upload your screenshot to this question. Note: You should see "8 examples, O failures". Upload Choose a File Capture.PNG has been removed.
