- coverage combine cannot process Cobertura files. Therefore, merge the .coverage folder individually to prevent failures when combining the coverage results.

- Fixed the failing merge_coverage job by ensuring the required coverage package is installed. Moved the common before_script to the default section.
- Added the test coverage badge to README.md.

- SpackOperation.py: The handle_result and trust_gpg_key methods were specifically updated with tests and docstrings. Also modified the add_mirror method as per the changes.
- SpackOperationUseCache.py: Similar to SpackOperation.py, this file also got enhanced tests and docstrings, specifically for the setup_spack_env method. The focus is on setting up the environment for a user spack cache setup along with testing of the caching behavior and improving documentation.
