# Jenkins-driven test runner for python-api-automation, ported from a sibling do-*-automation
# repo's Jenkins runner script (same stash/rerun/report-merge structure), adapted for pytest:
# dropped the `--headless` flag (Selenium-only, meaningless for pure API tests) and simplified the
# ENV -> postactivate-<env>.sh mapping to this repo's actual two files (PRODUCTION vs everything
# else -- postactivate-dev.sh already targets the stg3 environment here, unlike the source repo's
# separate STG2/STG3 files).
