Pull Request Overview

This PR adds an "Example Output" section to the README to document where and how output from tests can be viewed. It provides detailed visual examples for Visual Studio, Visual Studio Code, and Windows Terminal use cases.

• Added "Example Output" section with visual examples.
• Updated links to include new output images.
• Improved documentation to aid users in locating test output.

Comments suppressed due to low confidence (1)

README.md:139

• There is a grammatical error in this line. Consider replacing 'would expected' with 'would expect' to improve clarity.

If your tests (and the system under test) are correctly configured, then you should see output from the tests in the same places you would expected to see [output from xunit tests][xunit-output].
