The course’s lab aims at training the students in the use of integrated development environments and refactoring tools that will be employed for the developments of the course's project. The lab further focuses on issues related to the different phases of the project (development phase, refactoring phase).

Learning Objectives & Expected Outcomes

The study and application of best practices, patterns and refactoring techniques that allow to avoid issues of poor software design/implementation. The main outcomes of the course is that the students will be capable to:
  • Identify issues of poor software design/implementation. 
  • Improve the quality of software that suffers from issues of poor software design/implementation by applying design patterns and refactoring techniques.
