What is the difference between test plan and test strategy?

The test plan and test strategy are two important documents in the field of software testing and quality assurance. While they are related and often used together, they serve different purposes and focus on different aspects of the testing process.

A test plan is a detailed document that outlines the approach, objectives, scope, and schedule of testing activities for a specific project. It provides a roadmap for the testing team, describing the test objectives, test deliverables, test environment, test resources, and test schedule. The test plan also includes the test strategy, test techniques, and test levels to be followed during the testing process. It is a comprehensive document that guides the testing team throughout the project and ensures that all necessary testing activities are planned and executed effectively.

On the other hand, a test strategy is a high-level document that defines the overall approach and guidelines for testing across multiple projects or within an organization. It focuses on the broader aspects of testing, such as the selection of testing tools, test automation approach, test environment setup, and resource allocation. The test strategy provides a framework for consistent and standardized testing practices within an organization. It outlines the testing objectives, test levels, and test techniques to be followed across different projects. The test strategy document is usually created at the beginning of a project or when there is a need to align testing practices across multiple projects.

In summary, the main difference between a test plan and a test strategy is their scope and level of detail. The test plan is project-specific and provides a detailed roadmap for testing activities, while the test strategy is more generic and focuses on defining the overall approach and guidelines for testing across multiple projects or within an organization.
