# Run tests using pytest, e.g. from the root directory
|
|
# $ python3 -m pytest --ignore tests/testing/ -s -vvv
|
|
#
|
|
# If there are any breakags, the best way to see differences is using a diff:
|
|
# $ diff tests/data/scripts_pythondistdeps/test-data.yaml <(python3 tests/test_scripts_pythondistdeps.py)
|
|
#
|
|
# - Test cases and expected results are saved in test-data.yaml inside
|
|
# TEST_DATA_PATH (currently ./data/scripts_pythondistdeps/)
|
|
# - To regenerate test-data.yaml file with the current results of
|
|
# pythondistdeps.py for each test configuration, execute this test file
|
|
# directly and results will be on stdout
|
|
# $ python3 test_scripts_pythondistdeps.py
|
|
#
|
|
# To add new test-data, add them to the test-requires.yaml: they will be
|
|
# downloaded automatically. And then add the resulting dist-info/egg-info paths
|
|
# into test-data.yaml under whichever requires/provides configurations you want
|
|
# to test
|
|
# - To find all dist-info/egg-info directories in the test-data directory,
|
|
# run inside test-data:
|
|
# $ find . -type d -regex ".*\(dist-info\|egg-info\)" | sort
|
|
#
|
|
# Requirements for this script:
|
