For Overdraft testing, we need to use the loan-tool.py which is a helper script written by BE developers. For more information: https://safibank.atlassian.net/wiki/spaces/ITArch/pages/217710593/Manually+testing+loan+using+loan-tool+and+API#Partially-repay-the-loan
It is not possible to create an Overdraft retrospectively, also it’s not possible to specify the duration of the grace period and fee period using standard API. Therefore we need loan-tool.py which contains a method to create an overdraft with a specified duration of the grace period and fee period:
./loan-tool.py overdraft-test-open [main_account_id] [principal] [fee] [penalty_interest_rate] [grace-period-duration] [fee-period-duration]
Provide grace-period-duration and fee-period-duration in the following format: PT{number_of_minutes}M or PT{number_of_hours}H
Past 1st due date (between 1 month two 2 months):
Prerequisites:
account that has 0 balance
Steps:
Create an overdraft with shorter grace but longer fee period using
overdraft-test-openmethod. E.g.:./loan-tool.py overdraft-test-open 0cd7e263-38b3-4c9b-a8ff-e8a63ea5a62f 500 50 0.05 PT2M PT720H
Transfer all the money from the main account to test the asset internal amount using
do-paymentmethod within the grace period duration (2 minutes in this case)./loan-tool.py do-payment bff6934b-3153-4c7b-adbe-77b299dc706f TEST_ASSET_INTERNAL_ACCOUNT 500
Past 2nd due date (after 2 months):
Prerequisites:
