Integration tests

[perennialAutodidact]

The app needs a few integration tests to ensure that the user experience is predictable from beginning to end.

This can be accomplished using longer, more complex tests on the App.jsx component.

The test should

• Render the app without crashing
• Fill out the form automatically, triggering and correcting validation errors on each of the form steps and ensuring that the values get entered in the form
• Click the Play button
• Ensure that the proper player names and initial scores get rendered in the scoreboard component and the proper number of tiles gets rendered in the gameboard
• Click through the game, making sure non-matches are reset and matches are removed, adding points to the correct player
• Verify that the game over screen renders both the "Player x wins!" and the "It's a tie" messages, depending on the outcome of the game
• Verify that the play again button resets the tiles and begins the game again
• Verify that the reset game button take the user back to the setup form
• Anything else that might be required
