Michelangelo van Dam has posted the fourth part of his "Quality Assurance in PHP projects" series to his blog today - a continuation of his emphasis on PHPUnit and testing his sample "Tic-Tac-Toe" game.

In parts one, two and three we focussed on writing tests for a game of tic-tac-toe, with in parts two and three we optimized our tests so they focus on the functionality of the individual parts Grid and Player, with a collection class Players to handle Player objects.

In this fourth part he focuses on the rules for playing the game and the unit tests to validate the correct flow. He covers one of his tests before, looking at the "can be played" validation for identical symbols. He modifies this to use a provider that gives the test the set of data to work from with varying symbols. He writes additional tests to be sure the game "stops after winning" and that it has a winner/which player is the winner. You can find the full game source (complete with these tests) on his github account.
