[Improvement]: Refactored test testToHumanReadableString of MemorySizeTest to paramerterized

[Monilnarang]

Aim:

Improve the test code by avoiding code duplication, improving maintainability, and enhancing readability. By converting the test into a parameterized unit test, we reduce boilerplate code, make it easier to extend by simply adding new input values, and improve debugging by clearly identifying which test case fails instead of searching through individual assertions.

Why are the changes needed?

• The same method call to toHumanReadableString is repeated multiple times with different inputs in the test testToHumanReadableString making it harder to maintain and extend.
• When this test fails, JUnit only shows which type of assertion failed, but not which specific input caused the failure.
• Adding new test cases requires copying and pasting new assertion instead of simply adding new data.

Brief change log

Parameterized the test testToHumanReadableString using @MethodSource. This reduces duplication, allows easy extension by simply adding new value sets, and makes debugging easier as it clearly indicates which test failed instead of requiring a search through individual assertions.
