Arshad For the above scenario U need to Do -
Integration Test (as Two Application have been integrated)
Performance -Load/Stress Test
(Not includin Functional/UI Test as they are basic and not related to Query asked)
I do agree with your comment but i will tell you in detail what exactly i wanted to test.
Scenario 1 : I have 50 friends in my friend list,three friends come online.Here i need to check whether all 3 friends are online and i can chat with them
How i'm testing the above scenario(Also suggest me any good way to test this) :
1.Open IE and login with my User name.
2.Open three different browsers such as Firefox,Chrome & RockMelt and login with three different User names(who are my friends).
3.Checking the online status of friends on chat window in IE(as i'm login in IE browser).
Scenario 2 : If all 50 Users come online on the same time.I need to check whether all 50 Users are online and i can also chat with them.
I'm looking an answer for Scenario 2.What tool or best method we can follow to test Scenario 2?
