Debugging Process: Steps involved in debugging are:

  • Problem identification and report preparation.
  • Assigning the report to software engineer to the defect to verify that it is genuine.
  • Defect Analysis using modeling, documentations, finding and testing candidate flaws, etc.
  • Defect Resolution by making required changes to the system.
  • Validation of corrections.

Debugging Strategies:

  1. Study the system for the larger duration in order to understand the system. It helps debugger to construct different representations of systems to be debugging depends on the need. Study of the system is also done actively to find recent changes made to the software.
  2. Backwards analysis of the problem which involves tracing the program backward from the location of failure message in order to identify the region of faulty code. A detailed study of the region is conducting to find the cause of defects.
  3. Forward analysis of the program involves tracing the program forwards using breakpoints or print statements at different points in the program and studying the results. The region where the wrong outputs are obtained is the region that needs to be focused to find the defect.
  4. Using the past experience of the software debug the software with similar problems in nature. The success of this approach depends on the expertise of the debugger
