Test Azure Spring Apps reliability with Gremlin Failure Flags. Inject latency and exceptions to validate circuit breakers and retry logic.
Applications on Azure Spring Apps usually arrive with resilience patterns already in place. Circuit breakers, retry templates, and bulkheads are standard in the Spring ecosystem, and their presence in the codebase creates a reasonable assumption that failure is handled.
The gap is between configured and verified. Add Failure Flags to your Spring application and you can close it. With Gremlin, you can:
- Confirm the breaker actually opens. A circuit breaker with a threshold nothing ever reaches is decoration. Inject repeated failures and watch for the state change.
- Check that it closes again. Recovery matters as much as tripping. Restore the dependency and confirm traffic resumes without a restart.
- Test your retry backoff. A retry policy without jitter turns a recovering dependency into a synchronized thundering herd. Latency injection makes that visible.
Teams that invested in these patterns usually want to know they work. Testing is the only way to find out.
Dependencies: Failure Test
Simulate a failed dependency by dropping all network traffic to the dependency.
Dependencies: Latency Test
Recreate poor network conditions by delaying all network traffic to a dependency by 100ms.
Unreliable Networks - Dependencies
Simulate unreliable network conditions when communicating with dependencies by adding latency to API calls. Test whether your users are affected when dependency response times degrade.
* Failure Flags works wherever you can add the SDK to your application and run the Gremlin sidecar. Not every language and platform combination has been individually tested, and not all are officially supported. Check our compatibility documentation for what's verified, or get in touch if you don't see your runtime.
