# This script is used to run OfflinePageSavePageLaterEvaluationTests.
# The test will try to call SavePageLater on the list provided as the input,
# and generate results of the background offlining. Then it will pull the
# results to the output directory.
#
# Example Steps:
# 1. Build chrome_public_test_apk
# 2. Prepare a list of urls.
# 3. Run the script (use -d when you have more than one device connected.)
# run_offline_page_evaluation_test.py --output-directory
# ~/offline_eval_short_output/ --user-requested -use-test-scheduler
# $CHROME_SRC/out/Default ~/offline_eval_urls.txt
# 4. Check the results in the output directory.
