Creating API Tests Low Effort API Testing for Microservices | CONFIDENTIAL • What has changed? – Migration to microservices triggering need for extensive API tests • Problem: – Creating API tests • What is our solution? – Leverage Istio sidecar to listen to API traffic data and create tests from the data – 10x speed in creating API tests • Can also be sped up by just navigating the application Significantly reduced time and cost for API testing for microservices architectures with Istio – Fewer failures higher up the test pyramid as a result of improved API tests • Istio benefits – Venky / Prasad

performance, we typically think about the function logic. We’ll see that a well designed function API can have an even larger impact.How will we compare performance? ● Benchmarks at this low level are advance(RandIter& iter, Diff n, random_access_iterator_tag) { iter += n; } ● Access token to make some API available only inside the library (like the default “package private” access modifier in Java) Empty
