A team uses Azure Pipelines to run unit tests for a JavaScript application. They want to see code coverage metrics in the pipeline summary and enforce a coverage threshold. What should they do?

Use the built-in 'npm test' task and rely on the test results to show coverage.

Use the 'Publish Test Results' task only, which includes coverage by default.

Use the Istanbul coverage tool and publish the coverage report using the Publish Code Coverage Results task.

Add a script that runs 'npm test --coverage' and then delete the coverage folder.

Which of the following is a valid way to configure test agents in Azure Pipelines?

Using a Microsoft-hosted agent pool

Using Azure Monitor to configure agents

Using Azure Boards to assign agents

Using Azure Artifacts to download agents

What is the primary goal of integration testing?

To verify that different components or services work together correctly

To validate the user interface layout

To measure the performance of the system under load

To test individual functions in isolation
