A First Example Part 1

Talking Points

• Present the problem
• You have to add tests. Assume that the application works as is; change no current behavior

Commits

• Add test cases for statement method
  • What did you add that wasn’t in the book?
  • Curious. Why did you choose minitest over rspec?
  • I’m noticing some patterns.
    • In #setup, you create your Customer and 3 instances of Movie. #setup is the only place that directly class those classes.
    • Later, you use @joe in every single test. Cool. You then pass a movie object to the Rental on the first line – for example: Rental.new(@child_movie, 3) and then add the rental to @joe.
  • Each test calls #add_rental then looks at @joe.statement.
    • How do you feel about this? Is it a good test pattern to call one method (#add_rental) and test its correctness by calling another method (#statement)?
  • What do the test names mean? test_2day_new_4day_child_3day_reg
  • Can you summarize the objects here and their responsibilities?
• add notes from book stating the problem
  • Can you summarize for our listeners?
