Explore advanced techniques for dynamically testing individual microservice releases in production environments in this 35-minute conference talk by Matt Turner from Tetrate. Learn how to leverage service mesh technology like Istio to achieve sophisticated traffic control and override-based testing for microservices within complex chains. Discover the benefits of testing new service versions in production for representative and reliable results. Understand the challenges of testing services in the middle of a chain and how to overcome them. Dive into the implementation of an Operator that auto-generates the necessary configuration, simplifying the process and reducing errors. Gain insights into the underlying configuration and how it's generated from Deployments. Walk through practical examples and best practices for implementing this advanced testing approach in your microservices architecture.
