 1.  **Identify modified integration tests** (usually Starting in `IT`).
 2.  **Run specific integration tests only** (isolated checks run quicker):
     ```bash
-    mvn verify -Penable-integration-tests -DFIRESTORE_EDITION=enterprise -DFIRESTORE_NAMED_DATABASE=enterprise -Dtest=ITTest#testMethod -Dclirr.skip=true -Denforcer.skip=true -fae

     ```
 3.  **Run the entire integration test suite** for the modified class if isolation tests pass:
     ```bash
-    mvn verify -Penable-integration-tests -DFIRESTORE_EDITION=enterprise -DFIRESTORE_NAMED_DATABASE=enterprise -Dtest=ITTest -Dclirr.skip=true -Denforcer.skip=true -fae

 ## Step 3: Full Suite Regressions
 
 Run the full integration regression suite once you are confident subsets pass:
 
 ```bash
-mvn verify -Penable-integration-tests -DFIRESTORE_EDITION=enterprise -DFIRESTORE_NAMED_DATABASE=enterprise -Dclirr.skip=true -Denforcer.skip=true -fae

 If you run into issues executing tests with the commands above, **consult the Kokoro configuration files** as the ultimate source of truth:
 
 -   **Presubmit configurations**: See `.kokoro/presubmit/integration.cfg` (or `integration-named-db.cfg`)
--   **Nightly configurations**: See `.kokoro/nightly/integration.cfg` 
+-   **Nightly configurations**: See `.kokoro/nightly/integration.cfg` (or `integration-named-db.cfg`)
 -   **Build shell scripts**: See `.kokoro/build.sh`
 
 These files define the exact environment variables (e.g., specific endpoints or endpoints overrides) the CI server uses!
