We can face different problems when test users start testing system in their environment and we want to be ready to react fast to all problems. To get information about system’s work we need advanced logging.
Read moreLoggers are one of most popular examples about interfaces for sure. And there are a lot of implementations of loggers. Some implementations are simple and yet powerful, some implementations may be more complex. All we have to is to select implementation we need and integrate it to our application. It seems like good idea at first place but as soon as we need to switch from one implementation to another we discover nasty dependencies we have to change in all places where we are logging. Let’s see how to avoid these dependencies.

Bad decisions will also waste many time of developers who have to use this library in their work. One of the most common mistakes made is mixing DAL functionality to business objects.
