UPDATED GROOVY TRANSLATION

Changes:

• Changed testing framework from org.junit.Test to org.junit.jupiter.api.*
• Test Cases are now based off of the Python translation instead of the Go translation
• Now testing for when a 3rd parameter is not given
• Using @Order Annotations for Test Cases
• Other small changes
