HOW IMPORTANT TESTING IS IN SDLC?

By
Software Testing is one of the important phases in SDLC because of the following reasons: -

• Its helps to verify that all the software requirements are implemented correctly or not.
• Identifying defects and ensuring they are addressed before software deployment. Because if any defect will found after deployment and force to fixed it, than the correction cost will much higher than the cost of it fixed it at earlier stage of development.

• Effective testing is demonstrates that software-testing function appear to be working according to specification, that behavioral and performance requirement appear to have been met.
• Whenever any system is developed in different components, its helps to verify the proper integration/interaction of each component to rest of the system.

• Data collection as testing is conducted provide a good indication of software reliability and some indication of software quality as a whole.
