What is the benefit of automating tests in a pipeline?

It speeds up the compilation of code

It eliminates the need for code reviews

It ensures tests run consistently on every build

It guarantees the application has no bugs

A team wants to see test results and code coverage in the pipeline summary so that developers can quickly identify failing tests and coverage gaps. What should be configured in the pipeline?

Use a release gate to display the test results.

Store the test results in a database and query them manually.

Publish test results and code coverage artifacts from the test tasks.

Send test results via email to the team.

A team has a cross-platform application that must be tested on Windows, Linux, and macOS. They use Azure Pipelines and want to run unit tests on all three operating systems in parallel. What should they configure?

Use a container job that runs a Linux container with Windows emulation.

Use a matrix strategy in the pipeline job to run the same job on multiple agent images.

Create three separate pipelines, one for each OS, and run them sequentially.

Use a single agent that has all three operating systems installed.

What is the main goal of a security gate in a pipeline?

To encrypt all communication between pipeline agents

To provide a backup of the code repository

To monitor the performance of the pipeline

To enforce security policies before code proceeds to later stages
