Description of Change

Testing

This pr enables testing of the algorithms in the repository
before we get to the stage of running tests on a CI. We will need to remove all
other code from every main function so that the only remaining code is a call to the test function.

for now this draft pull request shows how easy it is to enable testing.
adding it to the awesome CI will be as easy as adding
make test to a test step.
