This exam is worth 15 points and has 3 "questions", each represented by a unit test. Successfully manipulating the repository is worth 3 points. Each question is worth 4 points. The first 2 questions have the unit tests fully specified, and you must implement the ConnectFour class methods to ensure that they pass correctly. The final question only has a meaningful unit test name. You must create the unit tests to satisfy the name and then implement the ConnectFour class methods so that the test passes correctly.
