Migrate test Groovy files to Java using JUnit 5

1. List all groovy files of the current gradle module
2. convert groovy files to Java using Junit 5
3. make sure the tests are still passing after migration
4. remove groovy files

When converting groovy code to java code make sure that:

• the Java code generated is compatible with JDK 8
• when translating Spock test, favor using @CsvSource with | delimiters
• when using a @MethodSource, use the test method name, and suffix it with _arguments
• when converting tuples, create light dedicated structure instead to keep the typing system
• Instead of checking a state and throwing an exception, use JUnit asserts
• Do not wrap checked exception and throwing a Runtime exception, prefer adding a throws clause at method declaration
• Do not mark local variables final
