I think this is unnecessary. The naming convention of test_ and data_ align to know that this data provider is for the matching test.

Whoops forgot to share where the naming convention is identified the handbook 🤦‍♀️

A data provider is a secondary function which is linked to a test using a@dataProviderannotation in the docblock of the test method and is generally named after the test, replacing the test prefix in the method name with data.

In the core, some mock functions have the document and some don't. I appreciated @hellofromtonya's and @SergeyBiryukov's input on this.

I know. The handbook and similar test mocks needs some love to align for consistency. I agree!
