What is meant by [B]call-pair[/B]testing? Where it is used?
A call-pair is the connection between two functions in which one function "calls" the other function. Testing the functions where one function calls or refers the another function is termed as Call-pair Testing.
For example, you have to book a ticket in the Railway reservation page. When "Book Ticket" button is clicked it will call the another function "Unallocated Seats" to check for the availability status. Here the function Book Ticket is the main functionality which is tested, but while testing this function it will call the another function "Unallocated seats" for checking the availability status. Testing this type of function will come under Call Pair Testing. So, in this case both the functions are validated.
Call pair testing is mostly used in the Integration Testing, where after unit testing, you will integrate the unit tested components and test whether as a system it performs as per the specifications.
