AZ-400 Designing and Implementing Microsoft DevOps Solutions Exam

Design and Implement Source, Bug, and Quality Traceability

Implement End-to-End Code and Test Traceability

Code and test traceability ensures that every piece of code and corresponding tests within a project can be tracked from inception to deployment. This process aids in continuous visibility and accountability across the software delivery lifecycle.

Azure Repos

To enforce work item associations in commits and pull requests, use Azure Repos branch policies. These policies require:

• Work Item Linking: Ensuring that commits are linked to work items helps maintain a clear history of changes.
• Pull Request Validation: Pull requests should be reviewed and validated before merging to ensure quality and completeness.

Azure Boards

Azure Boards integrates with Azure Repos, allowing for seamless linkage between bugs, tasks, and code changes. Benefits include:

• Unified View: All work items, code commits, and pull requests are visible in a single interface.
• Automation: Automatic updates of work item statuses based on commit and pull request activity.

Azure Pipelines

Azure Pipelines play a critical role in publishing and correlating test results and code coverage. Key features include:

• Continuous Integration/Continuous Deployment (CI/CD): Automates building, testing, and deploying applications.
• Test Result Publishing: Provides insights into test pass rates and code coverage, ensuring that tests are consistently associated with the relevant code changes.
• Unified Quality Reporting: Combines data from different stages of the pipeline to present a cohesive quality metric.

By combining these tools, you can achieve a robust traceability system that ensures all code changes are trackable and verifiable through the entire development process.

Conclusion

In the "Design and Implement Source, Bug, and Quality Traceability" section of the AZ-400 exam, students need to understand how to manage and trace code changes effectively. Implementing end-to-end code and test traceability involves configuring Azure Repos for branch policies, integrating Azure Boards for linking bugs and tasks with code changes, and setting up Azure Pipelines for publishing test results. By mastering these areas, students will be able to maintain a clear, accountable development process that ensures high-quality outcomes.
