"Chaos engineering" in automated testing means:

1. _Planned chaos_: Automated tests intentionally introduce controlled failures or errors.

2. _System stress testing_: Automated tests simulate real-world faults to test system robustness.

3. _Failure mode simulation_: Automated tests mimic real-world failure scenarios.

4. _Resilience evaluation_: Automated tests assess system ability to withstand failures.

5. _Error tolerance testing_: Automated tests verify system functionality despite errors.

6. _Fault injection testing_: Automated tests intentionally introduce faults to test system recovery.

7. _Unplanned behavior testing_: Automated tests simulate unexpected system behavior.

8. _Continuous verification_: Automated tests continually evaluate system resilience.

Chaos engineering in automated testing proactively identifies weaknesses, ensuring systems can withstand real-world disruptions and errors, and improving overall reliability and resilience.
