Why APIs Require Dedicated Stress Testing

APIs represent the core business logic of modern web applications. An attack on an unoptimized REST endpoint or heavy GraphQL query can cause database CPU spikes, thread pool exhaustion in Node.js/Go/Java backends, and cascading microservice failures. Boota's API stresser generates targeted request surges to identify these bottlenecks.

  • Benchmark complex GraphQL nested resolver queries under heavy load.
  • Validate JWT authentication token validation performance under burst traffic.
  • Ensure rate limiting middleware returns HTTP 429 without backend processing overhead.

Frequently Asked Questions

Can I send custom JSON POST bodies during tests?

Yes. Boota allows you to specify custom request methods (POST, PUT, PATCH), JSON payloads, custom headers, and query parameters.

Can I test endpoints protected by API keys or Bearer tokens?

Yes. You can configure custom Authorization headers directly in your test configuration.
