Why is Testing required?

Software Testing as a separate activity in SDLC , is required because-

• Testing provides an assurance to the stakeholders that product works as intended.
• Avoidable defects leaked to the end user/customer without proper testing adds bad reputation to the development company.
• Separate testing phase adds a confidence factor to the stakeholders regarding quality of the software developed.
• Defects detected in earlier phase of SDLC results into lesser cost and resource utilization for defect resolution.
• Saves development time by detecting issues in earlier phase of development.
• Testing team adds another dimension to the software development by providing a different view point to the product development process.
