View source for General business logic: self-contained and easily testable business logic

==Objective / Overview==
'''Program business logic methods which don’t need to access the DB, are self-contained and are easily testable with automated tests.'''


==Desired Outcome==
* Faithfully reproduce the functionality of current Petra 2.x business logic methods.
* Creation of test cases that cover all the functionality of each business logic method.
** Logging of test case results


==Scope==
Some of the 'simpler' business logic methods that are needed for openPETRA are part of this project. There is another project which contains more complicated business logic methods.
