How to Test Multiuser App with no Control of Concurrency Issues?
Many of modern applications are designed to work simultaneously with many users. Concurrency has always been problem-plagued part of such software products.
It is not an easy task for the development team to choose and implement the appropriate concurrency control pattern and for a software testing company to check it.
Before proceeding to web site testing, desktop testing or mobile application testing testers should investigate the system under test. If it involves concurrency it is necessary to verify which concurrency control pattern is implemented in order to elaborate suitable test procedures.
Pattern with no control of concurrency issues is more prone to containing defects than other patterns of handling simultaneous access of many users to the same data.
To Test an Application With no Control of Concurrency Issues One Should:
- to combine manual testing and automated testing;
- to pay close attention to data integrity;
- to check how the system manages the situation when one user has deleted the record while several others are trying to edit them.
So, testing involving checking multiuser software with no control of concurrency is a difficult task. To cope with it thoroughly one must make necessary preparations and put an emphasis on problem-prone issues.
