Fix AssertionFailedError

✅ Solution

AssertionFailedError in Keycloak tests often arises from asynchronous operations or delayed propagation of data changes, leading to assertions being evaluated before the system reaches the expected state. To fix this, introduce explicit waits or retries using `TestingUtil.waitFor...()` or similar methods within your tests to ensure data consistency and eventual consistency before making assertions. Also, consider increasing timeouts for asynchronous operations, retries, and server responses to accommodate slower environments.
