Fix MultipleFailureException
in ELK Stack
✅ Solution
MultipleFailureException in Elasticsearch tests often arises when a single test case asserts multiple conditions, and several of these assertions fail. To fix this, refactor the test to isolate assertions into distinct, smaller test methods or use soft assertions (collecting all failures before throwing), making it easier to pinpoint the exact cause of failure and debug effectively. Thoroughly examine the test report to identify all failed assertions within the failing test case.
