Semyon Zikunov updated IGNITE-23138: ------------------------------------ Description: *Description:* The following tests are intermittently failing due to an {{AssertionError}} in Apache Ignite: * {{testOptimisticReadCommittedCheckContentionTxMetricNear}} * {{testOptimisticRepeatableReadCheckContentionTxMetric}} * {{testOptimisticReadCommittedCheckContentionTxMetric}} * {{testOptimisticRepeatableReadCheckContentionTxMetricNear}} * {{testPessimisticRepeatableReadCheckContentionTxMetric}} * {{testPessimisticRepeatableReadCheckContentionTxMetricNear}} The issue arises when the tests periodically fail at the {{assertTrue(GridTestUtils.waitForCondition())}} check. The condition compares the {{txKeyCollisions}} field in the transaction metrics, which sometimes returns an empty string. This leads to an {{AssertionError}} when attempting to validate {{{}coll1{}}}, indicating possible inconsistencies or timing issues with the metrics collection during test execution. *Tasks:* # Investigate the root cause of the {{txKeyCollisions}} field occasionally returning an empty string in the metrics. # Analyze whether timing or state propagation issues are causing the {{waitForCondition}} to pass before the {{txKeyCollisions}} metrics are populated. # Refactor the tests to ensure consistent metrics collection and validation, possibly adding additional synchronization or checks. # Verify the fix by running the tests repeatedly to confirm the flaky behavior is resolved. *Expected Result:* The tests run reliably without intermittent failures. The {{txKeyCollisions}} metrics are consistently populated, and the {{assertTrue}} check passes as expected, ensuring the tests no longer exhibit flakiness. was: 6 tests constantly fail with java.lang.AssertionError. All marked as flaky. High fail rate - more than 80%.
