Running would look like this:

somethingToDoBeforeEachGroup
populateDatabase
operateFirstUpdate
cleanDatabase
populateDatabase
operateSecondUpdate
cleanDatabase
somethingToDoAfterEachGroup
somethingToDoBeforeEachGroup
populateDatabase
XX
populateDatabase
YY
somethingToDoAfterEachGroup
...

Since the

afterTest

in

Delete tests

is empty, there would be no need to define it in the code.
