Why testing is required Or Why testing is Important in SDLC

Why testing is required.. ?

Ans. We need software testing for the following reasons
1. Testing provides an assurance to the stakeholders that the product works as intended.
2. Avoidable defects leaked to the end-user/customer without proper testing adds a bad reputation to the development company.
3. Defects detected earlier phase of SDLC results in lesser cost and resource utilization of correction.
4. Saves development time by detecting issues in an earlier phase of development.
5. The testing team adds another dimension to the software development by providing a different viewpoint to the product development process.
