In software testing, a test plan is a formal document that defines the testing strategy, scope, and objectives for a project. It outlines the resources, timelines, tools, and methodologies required to validate the software’s functionality and performance. Test plans include key elements like test objectives, environment setup, test criteria, and roles and responsibilities. This document serves as a guide for the testing team, ensuring all aspects of the software are thoroughly evaluated. A robust test plan minimizes risks, enhances test coverage, and supports efficient execution, contributing to the delivery of a high-quality product.
