Playing the game

In this section, we will test-drive the code to play the game. This involves submitting multiple guess attempts to the endpoint until a game-over response is received.

We start by creating an integration test for the new /guess route in our endpoint:

1. The first step is to code the Arrange step. Our domain model provides the assess() method on class Wordz to assess the score for a guess, along with reporting whether the game is over. To test-drive this, we set up the mockWordz stub to return a valid GuessResult object when the assess() method is called:

   @Test

   void partiallyCorrectGuess() {

       var score = new Score("-U---");

       score.assess("GUESS");

       var result = new GuessResult(score, false, false);

       when(mockWordz.assess(eq(player), eq("GUESS")))

               .thenReturn(result);

   }
