Testing is a process of executing a program with the intention of finding an error.

Whether the application is developed according to customer requirements or not.

To make sure all the defects are resolved and finally to deliver a risk free product to the customer.

Reasons for conducting WBTReasons for conducting WBT

As source code is visible to developers to finding

the errors and rectifying the errors is so easy.

Programmers will conduct WBT to reduce the many defects as soon as possible.
