Tofunmi Oguntibeju resolved FINERACT-2576.
------------------------------------------
Resolution: Fixed
> Add unit tests for MoneyTest in fineract-core
> ---------------------------------------------
>
> Key: FINERACT-2576
> URL: https://issues.apache.org/jira/browse/FINERACT-2576
> Project: Apache Fineract
> Issue Type: Test
> Components: Test
> Reporter: Tofunmi Oguntibeju
> Priority: Minor
>
> This PR adds a comprehensive {{MoneyTest}} suite covering all major
> operations on the {{Money}} class, including parameterized edge cases for
> floating-point precision, boundary values, and identity/immutability
> behaviour.
> *Test coverage added:*
> * {{plus(double)}} — parameterized cases including negative values and
> floating-point precision edge cases
> * {{total(Money...)}} varargs — aggregation of multiple {{Money}} instances,
> and exception thrown on empty input
> * {{total(Iterable<Money>)}} — iterable aggregation including single-element
> and empty-list exception cases
> * {{roundToMultiplesOf(double, int)}} — parameterized cases plus NaN return
> for negative values
> * {{roundToMultiplesOf(BigDecimal, Integer)}} — parameterized cases
> including zero and negative multiples
> * {{roundToMultiplesOf(Money, int)}} — with and without {{{}MathContext{}}},
> including zero-multiple passthrough
> * {{ceiling(double, double)}} — NaN cases and valid cases covering zero,
> exact multiples, and rounding up
> * {{floor(double, double)}} — NaN cases and valid cases covering negative
> step sizes and floating-point steps
> * {{getAmountDefaultedToNullIfZero()}} — null for zero, non-null with
> correct value for non-zero
> * {{dividedBy(BigDecimal/double/long)}} — identity optimisation (returns
> same instance when dividing by 1), correct results for division by 2
> * {{multipliedBy(BigDecimal/double/long)}} — with and without
> {{{}MathContext{}}}, identity optimisation for multiplier of 1
> * {{multiplyRetainScale(BigDecimal/double)}} — scale preservation at
> currency decimal places
> * {{percentageOf(BigDecimal)}} — 50%, 100%, and 0% cases
> * {{negated()}} — positive, negative, and zero (returns same instance for
> zero)
> * {{abs()}} — positive, negative, zero, and with {{MathContext}}
> * {{zero()}} — instance method with and without {{MathContext}}
> * {{getMc()}} — non-null {{MathContext}} assertion
> * {{copy()}} — value equality, same currency, different instance; copy with
> {{BigDecimal}} and {{double}} overrides
> Effectively increasing test coverage to 81%
