 This folder holds the test cases for **OpenAPI**.  
 
 ## Additional Docs
-No Additional information is needed for this test case.
+The `_bad_` tests are valid `.yml`/`.json` but invalid OpenAPI specs.
+The test extensions used are `.ymlopenapi`/`.jsonopenapi` instead of `.yml`/`.json`. This is to prevent the [YAML] and [JSON] tests from picking them up.
 
 ## Good Test Cases
 The test cases denoted: `LANGUAGE_good_FILE.EXTENSION` are all valid, and should pass successfully when linted.
