Description

This PR enhances the output of the swift test command by providing detailed information about each tool, command execution, and errors encountered during the test runs. The improved output format aims to make debugging more efficient by offering comprehensive details that help in identifying and resolving issues more quickly.

Motivation and Context

The current output of the swift test command provides minimal information, which makes it challenging to trace the root cause of test failures. This enhancement introduces a more informative output format that includes:

• Clarity of error sources.
• Detailed command execution outputs.
• Improved traceability of errors.
• Increased efficiency in debugging.
