Write tests for utils

Feature description

The files under the utils directory are completely untested (though some are tested indirectly through usage in plugins). We should write tests for each file in the utils directory, testing each method/constant that is exported, similar to how we have tests for each plugin file.

How the feature is useful

Ensures we don't accidentally break the functionality of a util when shipping a change to the library.
