System Testing and System Integration Testing

System Testing:- After integrating the components into a system, Checking the

functional, Non-functional requirements and usability of an application or system is

called system testing.

 

E.g.:- In G-mail application Inbox, Sent Mail, Trash, Compose Mail all are the different

components .Here we check whether all the components are functioning according to

the requirements are not.

System Integration Testing:-

 

Testing an application or system by combining all components or 

modules and checking its dependency and workflow among the components is called

system integration testing.

 E.g.:- Let us consider an ATM application .When we insert a card in an A.T.M machine

for transaction, first it checks whether the card is valid one or not. If valid then it

displays the Account details and current balance of the account holder after entering the

Secret PIN as per customer or user requirement. Here A.T.M machine is integrated with

Bank database and data is retrieved from the database. Here we test the dependency and

work flow of the A.TM machine and Database.
