Problems in legacy code

Verbatim click path implementation

  • [functional correctness] no transactional integrity
  • error prone when mail subject is used as filename
  • does not check for existing files

Maintainability

  • [Modifiability] No config file
  • [Modifiability] no central selector storage in Object Repository
  • [testability] no test cases
  • [Analysability]
    • inconsistent argument naming
    • data flow mostly "in", at best error "out"
    • flowcharts that "start weak, strongly go downhill from there on"
    • no modular GUI interactions which makes test cases hard to write
    • arguments as workflow-scoped variables

Error handling

  • [Reliability/Faultlessness] Inconsistent error handling
  • [Reliability/Faultlessness] Keine Business rule exception
  • bad input data -> instable handover2human implementation
