I followed the instruction in the readme.md to setup the game. First, I created a Stub Deck for testing purpose. The deck contains cards with small values only where there were no cards with more than 10 values. The test case is included in the TestBlackjack.java file. Then I ran the test case and observe the result. This is the output: Your cards are: 7 of Spades 9 of Spades Your total is 16 Dealer is showing the 2 of Spades Hit (H) or Stand (S)? User stands. Dealer's cards are 2 of Spades 3 of Spades Dealer hits and gets the 8 of Spades Dealer's total is 13 You won, 16 points to 13. From the above actual result, we see that the dealer get "hit" once only at the end and stop even when the total score was 13 only. According to rules of blackjack, the dealer should keep drawing cards if his / her score does not exceed 17. Thus, the dealer should not get "hit" only once when the total score is 13 only. The dealer should keep getting "hit" until it reached 17 or gone bust (more than 21). I suspect that in the Game component, there wasn't a iterator handling this case. The original code was fine but they should be wrapped by a while loop. The loop there keeps drawing cards if the dealer's score is more than 17, or end the game if it is more than 21.
