   "description": "The \"org.junit.jupiter.api.assertAll\" is used to group multiple individual assertions together. The advantage of using this method to group the assertions instead of calling them individually is that if one assertion fails, the others are still executed. Therefore, the user gains insight on the results of all tests, instead of only the tests up to the failed assertion, where the thrown exception would otherwise terminate the test execution.",

   "description": "Instead of calling \"System.exit\", which completely terminates the java virtual machine, the \"javax.swing.JFrame.dispose\" method closes the frame and its assigned resources in a more controlled manner. Closing the application this way, one has to make sure to terminate all running threads programmatically. While this may seem like a downside, it ultimately provides the most control, as ongoing processes can be completed before the program is terminated.",
