Remove duplicate TestTransformValidator and fix test placement

[Pritiks23]

Description

This PR began as an effort to add a new unit test for the [TransformValidator]function. During implementation, I discovered that a test with the same name already existed, causing a redeclaration error. This PR resolves the duplication, ensures the test is correctly placed, and confirms that the validator logic is covered by unit tests.
