You use an Azure Pipelines pipeline to build and deploy an app. You have a custom test task that has the following inputs: • testResultsFiles: **/TEST-*.trx • searchFolder: $(System.DefaultWorkingDirectory) • mergeTestResults: true Which format should you use for the input data of testResultsFiles?

You use an Azure Pipelines pipeline to build, test, and deploy an app named App1. You need to reduce how long it takes to complete unit and integration tests for App1. The solution must ensure that the code coverage testing ratio is maintained. What should you do?

You have an app that is deployed to two environments named Production-A and Production-B by using Azure Pipelines. You need to configure a release pipeline that will mark the app as complete and ready for release into the Production-B environment. The solution must meet the following requirements: • Ensure that there are no active Azure Monitor alerts in the Production-A environment before the app is marked as complete. • Minimize administrative effort. What should you do?
