What is the role of a test strategy in a software testing process?

The role of a test strategy in a software testing process is fundamentally about outlining how quality will be achieved throughout the project. A test strategy serves as a high-level document that details the overall approach to testing, helping to align testing efforts with the project's objectives and quality goals. This document includes aspects such as testing scope, testing levels (unit, integration, system, and acceptance testing), responsibilities, and how testing will support project milestones.

By establishing a clear direction and focus on quality, the test strategy informs all stakeholders about expectations regarding the testing process, which contributes to effective risk management and quality assurance throughout the software lifecycle. This is essential for ensuring that all testing activities are meaningful and contribute towards delivering a high-quality product.

The other options, while related to the testing process, do not encapsulate the overarching purpose of a test strategy as effectively. For example, determining tools, identifying team responsibilities, and defining deadlines are more specific tactical decisions that can be derived from the broader strategy rather than being the main focus of the strategy itself.
