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.
