# Merges coverage reports from cypress and jest tests
# and generates an HTML report to view and json report to submit to codecov
#
# For jest coverage to be collected and submitted correctly
#  * Ensure the *coverageDirectory* is set to "coverage-jest" in packages.json
#  * Ensure there is a npm "test" script
#
# For cypress collection to work correctly
#  * Ensure "babel" (and dependencies) are at the latest (possible) version (aligned with frontend-components preferably)
#  * Ensure the babel "istanbul" plugin is included and configured in babel.config.js
#  * Ensure "nyc" is configuerd to output to "coverage-cypress"
#  * Ensure there is a npm "test:ct" script
