# Step 6: Run your first resilience test (optional)
<a name="next-gen-tutorial-run-test"></a>

Resilience testing helps validate that your service operates and recovers as expected by injecting controlled faults using AWS Fault Injection Service (AWS FIS). In this step, you choose a test template, create a test for your service, and start a test run.

1. Navigate to your service and choose the Testing tab. You will see recommended resilience tests based on your service's architecture and resilience policy.

1. Select a test template (for example, **Availability Zone: recovery**). Choose **View details** to learn more about the recommended test.

1. Choose Edit test configuration, provide any required parameters, and save. This creates your test from the template - your configuration is saved and reused for future runs. You can edit your test configuration anytime.

1. Choose Start test to start a test run.

1. Monitor the run and review whether your recovery objectives were met.

```
# List the available test templates
aws resiliencehubv2 list-test-templates --region us-east-1

# Create a test for your service from a template
aws resiliencehubv2 create-test \
  --test-template-arn "arn:aws:resiliencehub:us-east-1:aws:test-template/aws-az-recovery:rtaz001" \
  --target-identifier "arn:aws:resiliencehub:us-east-1:123456789012:service/api-service:def456" \
  --parameters '{"availabilityZone": ["us-east-1a"]}'

# Start a test run
aws resiliencehubv2 start-test-run --test-id "{{test-id}}"

# Check the status and results of the test run
aws resiliencehubv2 get-test-run --test-run-id "{{test-run-id}}"
```
