Azure Test Plans is a tool for manual and exploratory testing, including test case management, test suites, and test configurations.

16. How do you integrate automated tests into an Azure DevOps pipeline?
Automated tests can be integrated into an Azure DevOps pipeline using tasks like “Visual Studio Test,” “NUnit,” “MSTest,” or “SpecFlow” depending on the testing framework used.

17. What is the difference between Azure DevOps and Jenkins?
While both Azure DevOps and Jenkins are CI/CD tools, Azure DevOps offers a more integrated and comprehensive suite of services, whereas Jenkins is an open-source automation server primarily focused on continuous integration.

18. Can you deploy an Azure web app to multiple regions using Azure DevOps?
Yes, you can create multiple deployment stages in an Azure DevOps release pipeline, each targeting a different region or environment.

19. How do you handle secrets in Azure Pipelines?
You can store secrets securely using Azure Key Vault or Azure Pipelines’ built-in secret variables.

20. What is the use of “Azure Resource Manager (ARM) templates” in Azure DevOps?
ARM templates allow you to define and provision Azure infrastructure as code, enabling consistent and repeatable deployments.

21. How can you enforce branch policies in Azure Repos?
Branch policies in Azure Repos help enforce rules like requiring code reviews, build validation, and work item association before merging changes into specific branches.

22. How do you rollback a deployment in Azure DevOps?
In Azure DevOps, you can use the “Rollback” feature to redeploy a previous version of the release in case of issues with the current deployment.

23. Explain the process of linking work items to commits in Azure Repos.
Work items can be linked to commits by mentioning the work item ID in the commit message, or you can use the Azure Boards web portal to link commits to work items manually.

24. What are approval gates in release pipelines?
Approval gates are used to pause a deployment at certain stages until manual or automated approval criteria are met.

25. How can you set up continuous deployment for an Azure Logic App using Azure DevOps?
Continuous deployment for an Azure Logic App can be achieved using the “Azure Logic App” task in the release pipeline, which deploys the Logic App’s definition to the specified Logic App resource.

26. What is “Infrastructure as Code”?
Infrastructure as Code (IaC) is a practice of managing and provisioning infrastructure through machine-readable definition files, such as ARM templates or Terraform scripts.

27. How can you manage releases across multiple environments in Azure DevOps?
Azure DevOps release pipelines allow you to define multiple stages corresponding to different environments, enabling you to manage releases across development, testing, staging, and production environments.

28. How do you handle versioning of artifacts in Azure DevOps?
Versioning of artifacts in Azure DevOps can be managed using the “Build Number” format or by using a custom script to determine the version number during the build process.

29. What is “Continuous Integration”?
Continuous Integration (CI) is the practice of integrating code changes from multiple developers into a shared repository multiple times a day. This is typically followed by an automated build and test process.

30. How can you automate the creation of an Azure virtual machine using Azure DevOps?
You can use ARM templates and Azure Resource Manager tasks in Azure DevOps to automate the creation of an Azure virtual machine.
