pytest: clean-test ## Runs pytest with coverage and creates coverage and test report
	## - puts the coverage results in the folder 'htmlcov'
	## - generates cobertura 'coverage.xml' (needed to show coverage in GitLab MR changes)
	## - generates 'report.html' based on pytest-reporter-html1
	## - generates JUnit 'report.xml' to show the test report as a new tab in a GitLab MR
	## NOTE: additional options pytest and coverage (plugin pytest-cov) are defined in .pytest.ini and .coveragerc
