I am constantly sifting through openmrs-core trying to find ways to improve it. One point was to increase code coverage so we can refactor/add features with confidence. This has proven to be a slow process, as the code base is big and adding tests after writing code is not the easiest.
What I noticed is that there is probably potential for removing/deprecating code that was once used but isnt anymore.
encrypt/decrypt (these methods are only referenced in the SecurityTest; also no other code under the openmrs org on github references it).
Would be great to get support on this!
