Research direction

First, review the existing test files in the test/unit folder to understand the test framework and style. Then, examine the utils source code to identify key functions and their expected behavior. Consider writing tests for utility functions that are self contained and have clear input/output. If the testing framework is not obvious, check the project's package.json or look for configuration files. Finally, ensure that the tests can be run with the existing test script and pass.
