Technical Details

Deep-Sky Planner has been designed from the beginning (1991) using object-oriented techniques, and takes extensive advantage of object-oriented design patterns and programming. Agile development methodology (modified scrum) has been employed throughout the development of version 8. Requirements analysis, UML modeling and automated testing round out the engineering effort.  Automated bug tracking and source code control help to manage the result.

The application has been developed over a period of 30 years and contains over 150,000 lines of C++ source code. Python scripts and the DUnitX framework support development and testing.

Most development occurs on a 3.3 GHz i5 machine running Windows 10 Professional (64-bit). In-house testing occurs on this machine, various computers running Windows 8.1 and 7 (a mix of 32 & 64 bit editions). The test team uses a variety of desktop, laptop and tablet computers.
