Test that there are no regressions: Uninstall moodlemlbackend if it was already installed sudo pip uninstall moodlemlbackend Install the new version During peer review: (no new release available yet) git clone git://github.com/dmonllao/ https://github.com/dmonllao/moodle-mlbackend-python ; cd moodle-mlbackend-python ; sudo pip install . -e During integration review and testing: (new versoin released) sudo pip install moodlemlbackend Run vendor/bin/phpunit -c analytics , they should all pass with no skipped tests Test the accuracy improvement: Download the attached MDL-60667 .dataset.csv Execute python -m moodlemlbackend.evaluation 'whatever' '/tmp/dataset-mdl-60667' '/YOUR/PATH/TO/ MDL-60667 .dataset.csv' '0.7' '0.05' '10' | python -m json.tool Copy these results to a .txt file to later compare them with the previous version Change your moodlemlbackend version to the previous one: If you cloned the repo you will also need to rm -rf /PATH/TO/YOUR/CLONE/moodlemlbackend.egg-info sudo pip install moodlemlbackend==0.0.4 Check that you got version 0.0.4 by executing python -m moodlemlbackend.version Execute again python -m moodlemlbackend.evaluation 'whatever' '/tmp/dataset-mdl-60667' '/YOUR/PATH/TO/ MDL-60667 .dataset.csv' '0.7' '0.05' '10' | python -m json.tool The score value should be lower than the previous execution value
