• You have implemented new methods to make the tests pass.
• Your code is free from errors
• Your code is well formed, correct, and efficient.

10 points per

• Your Git commit history in your project shows that you developed the tests first. That means you will have multiple commits. You must use Git to demonstrate to me that tests were written before code was implemented.

• Make sure you follow the rules of TDD:

• Do not write any code unless it’s to make a failing test pass.

• Do not write any more of a unit test than is sufficient to fail, and not compiling is failing.

• Do not write more code than you need to make the current unit test pass.

Instructor comments:

You need to support what toString was intended to do. Hardcoding is the first step, add a car that's blue and watch it fail.

Check E360 for your Grade as an unchecked box does not mean you were not given any points,
a checked box doesn't mean you were given full points.
