At Neo4j Aura, chaos testing is a crucial aspect of ensuring the stability and performance of their cloud-based software. To tackle this challenge, they've developed an automated workflow using Argo Workflows alongside Backstage, their internal developer portal. Engineers can trigger chaos tests via a simple API request, which sends a POST request to a microservice that forwards it to the correct Kubernetes cluster. The Argo Workflow Controller then executes the test, overloading the database with specific Cypher queries and verifying its health after the test. Logs and results are collected and returned to Backstage, allowing engineers to monitor execution details without needing direct Kubernetes access. This approach enables chaos testing at scale, making it simple and accessible for engineers across different teams.
