Error Handling Testing

    Usage:

  • It determines the ability of applications system to process the incorrect transactions properly
  • Errors encompass all unexpected conditions.

  • In some system approx. 50% of programming effort will be devoted to handling error condition.

    Objective:

  • Determine Application system recognizes all expected error conditions
  • Determine Accountability of processing errors has been assigned and procedures provide a high probability that errors will be properly corrected
  • Determine During correction process reasonable control is maintained over errors.
    How to Use

  • A group of knowledgeable people is required to anticipate what can go wrong in the application system.
  • It is needed that all the application knowledgeable people assemble to integrate their knowledge of user area, auditing and error tracking.
  • Then logical test error conditions should be created based on this assimilated information.
    When to Use

  • Throughout SDLC.
  • Impact from errors should be identified and should be corrected to reduce the errors to acceptable level.
  • Used to assist in error management process of system development and maintenance.
    Example

  • Create a set of erroneous transactions and enter them into the application system then find out whether the system is able to identify the problems..
  • Using iterative testing enters transactions and trap errors. Correct them. Then enter transactions with errors, which were not present in the system earlier.
