Fix: Improve `wp_unique_id_from_values()` unit tests

[Debarghya-Banerjee]

Trac Ticket: Core-63175

Problem Statement

The original unit tests for the wp_unique_id_from_values() function relied on specific hash outputs, which caused test failures in certain hosting environments due to differences in how data is serialized and hashed. These tests assumed consistent hash values across all environments for the same input, which was not guaranteed. Additionally, the tests did not properly validate the handling of the prefix parameter.

Solution

• Ensured Consistent Output:

  • The tests were updated to ensure that the same input data consistently produces the same ID, regardless of the environment. This removes the reliance on specific hash values and focuses on validating consistent behavior.

• Verified Uniqueness:

  • The tests now verify that different input values result in distinct, unique IDs. This ensures the function generates unique identifiers for different data sets.
