The purpose of testing in software development is to ensure that the application functions correctly and meets the specified requirements. Testing helps identify and fix defects, ensuring the software is reliable, secure, and performs as expected.
A testing strategy is a comprehensive plan that outlines how testing will be conducted throughout the development process. It includes test objectives, scope, resources, test environments, and the types of testing to be performed, such as unit testing, integration testing, system testing, and acceptance testing. A well-defined testing strategy ensures thorough test coverage, timely defect identification, and smooth delivery of a high-quality product.
