Whether this application is residing in a desktop machine under developer’s desk or hidden in a production vault guarded by the Bastard Operator From Hell – does not matter.

Never Test Logging

software-development-2-logo

Technical logging is usually not tested. As commentator write on stack overflow: I practice TDD/BDD pretty religiously and I almost never test logging.

Use Java annotation deprecated the right way

java-logo

There is hardly anything more infuriating that seeing a method @Deprecated without a proper documentation. I feel lost. Should I still use the method? Probably that is not the intention of the developer, that is why he/she added the deprecation annotation. Should I use something else? So…. What are the rules using @Deprecated?
