What is the difference between unit testing and integration testing?
A. Unit Testing:It is a testing activity typically done by the developers not by testers,as it requires detailed knowledge of the internal program design and code. Not always easily done unless the application has a well-designed architecture with tight code. integration testing:testing of combined parts of an application to determine if they function together correctly. The ‘parts’ can be code modules, individual applications,client and server applications on a network, etc. This type of testing is especially relevant to client/server and distributed systems.
