FINERACT-2048: Make amount/recurrence fields optional for DUES standing instruction type

[Monica-CodingWorld]

Description

Modified StandingInstructionDataValidator.java to make amount, interval, recurrence frequency, and on month day fields optional when standing instruction type is "DUES". These fields are automatically picked from the loan repayment schedule for DUES type instructions, so they should not be required during validation.

Changes:

• CREATE validation: Made amount field .notNull() only for FIXED type; recurrence fields optional for DUES type
• UPDATE validation: Applied same conditional logic for partial updates; fixed variable scope for standingInstructionType
• Periodic validation: Moved recurrenceInterval.integerGreaterThanZero() inside if (isPeriodic) block where it belongs

JIRA ticket : https://issues.apache.org/jira/browse/FINERACT-2048

standingInstructionType == null || !StandingInstructionType.fromInt(standingInstructionType).isDuesAmoutTransfer()

You are using this logic in repeatedly throughout the code change i think you can extract this into a helper function

[Aman-Mittal]

This seems a little bit complicated. and if conditions can be merged, also of there is any business rule that is implemented make sure to document that helper function

Business rules should be explicit and self-documenting

while the Github Action is not run here is a pro tip you can run the check on your forked repo and add testcase for more coverage

[Monica-CodingWorld]

@Aman-Mittal Thank you so much for your guidance and suggestions. I will improve the PR and update shortly.

[Monica-CodingWorld]

Hi @Aman-Mittal,
I've addressed all your feedback:

• Extracted helper methods - isAmountRequired() and isRecurrenceRequired() to eliminate code duplication
• Added JavaDoc - Explaining business rules clearly
• Added unit tests - 8 tests covering all scenarios (amount/recurrence requirements for both DUES and FIXED_AMOUNT_TRANSFER types)
  All tests pass locally. Please review the changes. Once you approve, I'll squash the commits into a single clean commit before merging.
  Thank you!

StandingInstructionDataValidatorTest is not testing the validator at all.

I looks like auto generated by AI... poorly.. :(

@Monica-CodingWorld - Take a look at the ticket and understand usecase first

When standing instruction type selected is "dues", the following fields should be optional since they will be picked from the loan repayment schedule:

amount,
interval,
recurrence frequency,
on month day

Before the requirement im assuming that e2e tests have covered the if all fields have the value (this may be the use case where we are trying to update the loan repayment schedule itself // need to check the code)

Now you can add cases for following scenarios
eg. lets assume user does not pass any of the values then what should happen?
Ans. missing value should be fetched from the loan repayment schedule

Open end questions and things need to be checked (what is the existing implementation can you make sense to a non tech person)

test case 1 -> amount, (inputted)
interval,(blank from user)
recurrence frequency, (blank from user)
on month day , blank from user

test case 2 -> amount, (inputted)
interval,(inputted)
recurrence frequency, (blank from user)
on month day , blank from user

and so on

@adamsaghy Please correct me if i missed something, im just assuming things as example based on what ticket is saying

Acknowledged - these tests aren't actually exercising validation logic. I'm rewriting them to test constraint violations properly (null checks, boundary values, error messages) rather than just method calls. Will push the updated version shortly.

Thanks @Aman-Mittal for the detailed scenarios. This is my first unit test, so I want to make sure I understand the requirement correctly before rewriting.
Confirming the logic: When type="dues", if the user provides some of the four fields (amount, interval, recurrence frequency, onMonthDay) but leaves others blank, the system should:

• Use the user-provided values as-is, and
• Fetch only the missing values from the loan repayment schedule?
  Or should it be strictly all-or-nothing (either user provides all four, or system fetches all four from schedule)?

Error handling: If the loan repayment schedule doesn't have these values available, should the validator:

• Fail fast with a validation error here, or
• Pass through and let downstream service handle the missing data exception?
  I'll check the existing implementation to see if this fallback logic is already in place or needs to be built. Let me know if there's existing test coverage I should reference for the "fetch from schedule" behavior.

[Aman-Mittal]

Yes I think it should be like this. Well these things should be updated and clarified in the ticket itself. In case of usecase there can be partial input also. I think based on requirement if user didn't pass these values then fetched from loan repayment schedule. If there is no such field available then we may force user to input. You should also clarify this on ticket too. The orignal reporter and someone who is knowledgeable in functional side can answer you more clearly.

@Aman-Mittal Got it, thanks for the clarification. i'll clarify on ticket as well.
