Re: How to check the concurrency in Web application testing
Concurrency scenarios occur when 2 or more persons are trying to access same record set and trying to modify it.Most of the test scenarios in concurrency testing will result into negative test cases.
Let us take an example.Imagine there is a CRM software and it has a sales process module.A sales process clerk opens order process module clicks on an order and starts to process it.At the same time another sales person also tries to access same record.This is a concurrency scenario.
Expected result: Sales processor person 2 should be able to view this record in read only mode.
