A test strategy is a high-level document that outlines the overall approach and objectives for testing a project or software application. It defines the scope, objectives, resources, and schedule for testing activities.

A test strategy is crucial because it provides a roadmap for testing efforts, ensuring that testing aligns with project goals, identifies potential risks, and sets clear expectations for the testing team.

A test strategy is a high-level document that provides an overarching view of the testing approach, whereas a test plan is a detailed document that outlines specific test cases, test data, and test execution schedules.

The test strategy should be developed early in the project lifecycle, ideally during the project planning phase, to ensure that testing aligns with project goals and objectives.

Risk assessment in a test strategy helps identify potential challenges and risks that could impact the testing process. It allows the testing team to plan for mitigation strategies.
