# This script tests all documentation tests marked with ```no_run. It temporarily removes the
# ```no_run markers, applies a patch to add rate limiting to the jolpica::get::get_response_page
# function or, if --local_jolpica is passed, to change jolpica::api::JOLPICA_API_BASE_URL to
# "http://localhost:8000/ergast/f1" and disable default rate limiting. It then runs the
# documentation tests, and lastly reverts all changes. Since it makes multiple code modifications
# that need to be reverted, it first checks that the working directory is clean before proceeding,
# in order to avoid losing any uncommitted changes.
