The last two specifications have the instantiation of the TicTacToeCollection class repeated. We can move it to a method annotated with @Before. The effect will be the same (the class will be instantiated before each method annotated with @Test is run) and we'll remove the duplicated code. Since the same instantiation will be needed in further specs, removing duplication now will provide even more benefits later on. At the same time, we'll save ourselves from throwing ...
