What is the Usefulness of Testing?

Objective of testing is to discover and fix as many errors as possible before the software is put to use. That is before it is shipped to the client and the client runs it for acceptance. In software development organizations, a rift exists between the development and the testing teams. Often developers are found questioning about the significance or even need to have the testing resources in the project teams. Whoever doubts on the usefulness of the testing team should understand what could happen if the application is delivered to client without testing? At the best, the client may ask to fix all the defects (free of cost) he would discover during the acceptance testing. At the worst, probably he would sue the development firm for damages. However, in practice, clients are often seen complaining about the deliverables and a couple of defected deliverables are sufficient for breaking the relations next to the cancellation of contract.
