A structured document provides a framework for executing software testing activities. It outlines the scope, approach, resources, and schedule of intended testing efforts. For example, such a document might detail which testing types (e.g., unit, integration, system, acceptance) will be employed, the environments required, and the roles and responsibilities of the testing team.
Effective planning in this area offers numerous advantages. It ensures consistent testing practices, minimizes risks, and improves the overall quality of the software. Historical context reveals the growing importance of well-defined testing methodologies, driven by the increasing complexity and critical nature of software applications.
