guide: Provide mapping of old tests-rule association to latest rule-aligned Tests

[chetan-rathore]

Background

• Previously, test files were not strictly aligned with individual rules:
• A single test could cover multiple rules.
• In some cases, multiple tests would cover the same rule.
• This made it harder to directly trace which test validated which rule.

Recent Change

• We are transitioning the test structure so that:
• Each test now maps to exactly one rule.
• This makes it easier to identify which test verifies a given rule.
• Users who were familiar with the old test structure are struggling to determine:
  • How an old test file corresponds to the new rule-aligned test file(s).

Proposed Solution

• Create and maintain a mapping table that provides:
• Old test file(s) → New test file(s)
• Rule IDs (before vs after restructuring)
