The test file (test/eslint-plugin.test.ts) only tests plugin.configs.recommended. There are no tests for recommended-for-s4hana, which is the primary target of this change. The S4HANA-specific behavior — ESLint recommended rules becoming warn instead of error, and mockserver.js being ignored — is entirely untested.

QA Report
Tested eslint-plugin-fiori-tools using a Fiori S/4HANA project with recommended-for-s4hana config.
The following scenarios covered:

• Config loads, ESLint server starts without errors ;
• webapp/localService/mockserver.js produces no lint output (ignored)
• no-unused-vars (ESLint recommended rule) shows as warning in S/4HANA config;
• SAP-specific rules (e.g. sap-no-localstorage) still show as error ;
• Custom files in webapp/localService/ (non-mockserver) are still linted ;

All scenarios passed ✅
