 - **FakeClock and Sleeper:** Use `FakeClock` and `Sleeper` for any logic involving timeouts, delays, or expiration.
 - **Empirical Reproduction:** Before fixing a bug, always create a test case that reproduces the failure.
 - **Base Classes:** Leverage `CommandTestCase`, `EppToolCommandTestCase`, etc., to reduce boilerplate and ensure consistent setup (e.g., clock initialization).
+- **Gradle Test Patterns:** When running tests to investigate fixes in the "core" directory, try to first use the "standardTest" Gradle task. It is faster than the "test" task, which includes the "fragileTest" task. Only run the full "test" task after "standardTest" succeeds.
 
 ### 6. Project Dependencies
 - **Common Module:** When using `Clock` or other core utilities in a new or separate module (like `load-testing`), ensure `implementation project(':common')` is added to the module's `build.gradle`.
