Problem Statement

Background

response.rb is the default class to interact with the responses table, which stores all answers of each questionnaire.

What’s wrong with it?

response.rb is a fairly complex file. It contains a lot of methods that are long and hard to understand. These methods need to be broken down into simpler and more specific methods that are easier to read/understand. Also, the few instances of code duplication that exist should be removed.

Problems

Problem 1:Refactor display_as_html method

Write failing tests first

Split into several simpler methods and assign reasonable names

Extract duplicated code into separate methods

Problem 2:Refactor self.get_volume_of_review_comments method

Write failing tests first

Convert duplicated code into loop

Problem 3:Rename method and change all other places it is used

Write failing tests first

get_total_score → total_score

get_average_score → average_score

get_maximum_score → maximum_score

Problem 4:Use sort_by(&:seq) instead of sort { |a, b| a.seq <=> b.seq }

Write failing tests first

Problem 5:Use find_by instead of where.first

Write failing tests first

Problem 6:Complete the pending tests in grades_controller_spec.rb, and write integration tests for newly-created methods. Refactor corresponding methods, and only then finish pending tests.
