What does the term 'software testing' mean?

Software testing is the process of verifying and evaluating the quality of a software product to identify defects and confirm compliance with requirements.

Main objectives of testing:

• Detect errors and bugs before the product release.
• Check functionality, performance, security, and usability.
• Ensure the product meets technical and business requirements.

Example: when developing a web application, a tester creates scenarios that verify the correctness of forms, error handling, browser compatibility, and load stability.
