| Origin | FEA505 |
Test description / objective
Purpose of this test is to verify that application scales as intended and resists application errors.
Pre-state
Service is up and running and is configured to be scaled
Test Steps
| Step | Verify | Some notes |
|---|---|---|
| 1. | Crash one container | Ensure that new containers takes its place |
| 2. | Ensure that multiple containers are running and are accessible from gateway | - |
| 3. | Simulate multiplate users to overload application | Ensure that containers are created according to volume of requests |
| 4. | Stop traffic to application | Verify that excess containers are destroyed |
| End-State |
After the test, service should've been accessible to all simulated users, and multiple containers should've been created and destroyed in the process.
Determination of test result (Pass / Fail Criteria)
- PASS condition: All steps are completed succesfully and system stays responsive during testing
- FAIL CONDITION: System crashes or fails to create additional containers during testing.
