Is your change request related to a problem? Please describe.
As described in the tests section of the Library Guidelines, Contributors libraries ar expected to have tests exercised in CI on pull requests and the main branch.

This library currently doesn't have tests.

Describe the solution you'd like
There should be at least one test in the test directory. It can be a minimal usage example similar to the quick start in the repository README.
