Recall that in TDD, you write the test for a given behavior before you code the A Message object has a name and contains several Command objects. When driving Mars rovers, we have to be very intentional about how we move a rover across the harsh landscape to reach its destination. We need to write rules that move our objects around the game environment. Many Git commands accept both tag and branch names, so creating this branch may cause unexpected behavior. Code a third test using, "constructor sets a value passed in as the 2nd Codewars is where developers achieve code mastery through challenge. The code_verifier instead must be sent along the POST request to the authorization server for requesting the final access token.
