# IMPORTANT NOTICE
|
|
# ----------------
|
|
# This test file has a special behaviour. After each request, a call to fix_rate_limit_after_request must
|
|
# be performed, in order for the rate_limiting process to work appropriately in test time.
|
|
# If you want to see why, feel free to refer to the source of the "hack":
|
|
# https://github.com/alisaifee/flask-limiter/issues/147#issuecomment-642683820
