Code Review

This pull request focuses on cleaning up and modernizing the test suite across multiple modules. Key changes include renaming test methods to remove the redundant 'test' prefix, updating exception handling in test signatures to use a generic Exception, and adjusting class and method visibility to package-private to align with JUnit 5 best practices. Additionally, it migrates several tests from JUnit 4 to JUnit 5, replaces legacy assertions with AssertJ, and removes several unused shell scripts. I have no feedback to provide as the changes are consistent improvements to the codebase.
