Definition of Testing

Testing in the software development lifecycle (SDLC) is a process used to identify the correctness, completeness, security, and quality of software. It involves executing a program or application with the intent of finding software bugs (errors or other defects).

Requirement of Testing

Testing is a critical requirement in the SDLC for several reasons:

• Quality Assurance: Ensures that the software meets the specified requirements and works as expected.
• Bug Identification: Helps in identifying bugs or defects in the software before it is deployed.
• Security: Ensures that the software is secure and free from vulnerabilities.
• Performance: Assesses the performance of the software under various conditions.
• User Satisfaction: Ensures that the software provides a good user experience and meets user needs.
• Compliance: Ensures that the software complies with relevant standards and regulations.
