Test-Driven Development: write tests before writing code.

Unit testing results in modular code. Modular code is:

• easy to test.
• immune to bugs.
• easy to understand.
• scalable.

Setup

Test Cases

Inside requirements.txt, identify meaningful test cases:

• adding an item if not already added
  • [identify test case 1]
  • [identify test case 2]
• removing an item
  • [identify test case 3]
  • [identify state exception test case]
• checkout
  • [identify test case 5]
  • [identify test case 6]
  • [identify test case 7]
  • [identify state exception test case]

Should I test the getters/setters/constructors?

No. They don't offer meaningful logic that's worth unit testing.

Good Luck!
