Which Azure DevOps feature would you use to track testing and quality assurance?

In the context of tracking testing and quality assurance within Azure DevOps, Azure Test Plans is specifically designed to support these functions. It offers tools for managing test cases, capturing test results, and running both manual and automated tests. This allows teams to ensure that their applications meet quality standards and fulfill the requirements defined earlier in the development process.

Azure Test Plans allows for detailed tracking of testing progress, creation of test plans, test suites, and test cases, along with the ability to generate reports on testing activities and outcomes. Its focus on organizing and executing tests makes it the most suitable option for maintaining quality throughout the software development lifecycle.

The other features, while integral to Azure DevOps, serve different purposes: Azure Boards is mainly for managing work items and tracking project progress, Azure Repos is focused on source control for managing code, and Azure Pipelines automates builds, tests, and deployments. None of these alternatives provide the targeted functionality for comprehensive test case management and quality assurance that is inherent in Azure Test Plans.
