# script: Kraken Unit Test
# author: Serkan Korkmaz, serkor1@duck.com
# date: 2024-05-18
# objective: This unit test is a sample of of the functions
# available in the package for CI/CD. Most tests fails on Github
# because of georestrictions - and this makes the library prone to
# bugs and errors for future contributions. This unit test is a sample test
# to filter errorneous pushses from contributors from the get go.
#
# All tests has to be done locally - but this is an initial security measure
# script start;
