User Story

As a player, I want to guess a secret 5-letter word so that I can test my vocabulary and logic.

Acceptance Criteria

• The Word Guess game allows the player up to a fixed number of guesses (N).
• After each guess, it reports whether the guess is correct.
• The game ends on player successfully identifying the word or after N incorrect guesses.
• Score is based on the number of attempts remaining.

Details

• Create a clean internal method to compare guesses.
• Extract guess-checking logic to make it unit-testable.
• Add JUnit tests for:

  • correct guess within N tries
  • invalid guess (wrong length or characters)
  • multiple incorrect guesses
