Parallel Testing Technique :
Usage
|
" To ensure that the processing of new application (new version) is consistent with respect to the processing of previous application version.
|
Objectives
|
" Conducting redundant processing to ensure that the new version or application performs correctly.
" Demonstrating consistency and inconsistency between 2 versions of the application.
|
How to Use
|
" Same input data should be run through 2 versions of same application system.
" Parallel testing can be done with whole system or part of system (segment).
|
When to use
|
" When there is uncertainty regarding correctness of processing of new application where the new and old version are similar.
" In financial applications like banking where there are many similar applications the processing can be verified for old and new version through parallel testing.
|
Examples
|
" Operating new and old version of a payroll system to determine that the paychecks from both systems are reconcilable.
" Running old version of application to ensure that the functions of old system are working fine with respect to the problems encountered in the new system.
