E608. Refactoring and Testing - Course Related Classes

Classes Involved:

• models/course.rb (76 lines)
• models/course_participant.rb (94 lines)
• models/course_team.rb (116 lines)
• models/course_node.rb (95 lines)

What it does: Involves creation and management of courses in Expertiza

What needs to be done:

• It is not clear what a method named 'create_node' is doing in the 'course' class. Refactor by renaming this method appropriately.
• In the course_team class the import method seems to be doing too many things. See if this method can be broken down into smaller methods with specific functionality.
• The 'get' method in course_node.rb appears to be doing a lot. Refactor this method by breaking it up into smaller methods.
• Look for any unused methods or variables in these files.
• Also apply other refactorings such as Rename variable, Rename method to give the variables and methods more meaningful names.
• Write unit tests for all the methods in each of the listed model classes.
