Most of them didn't know we can test APIs in a programmatic way How To Test? Actions > How to detect failures? > How to recover services quickly? > How to contribute to business / users / customers? Lack of a Whole-Image due to Independent Develop-Ability and Deployability > One team test only one Microservice(s) > Lack of testing beyond teams / silos
To Analyze Root Cause and Distinguish Which Microservices Caused Didn't Become Established > Few developers maintained them > Hard to read and implement for developers and a Product Manager Left to Developers' Own Choice > How to analyze root cause? > How to distinguish which Microservices caused failures?
to write proper tests with examples > Added / updated Karate features based on real needs Worked With the Product Development Team > Can implement with less code > Easy to read, implement, and maintain for developers and the Product Manager > BDD (Behavior-Driven Development) style
chat channel > Don't need to access to CI Server to change configurations Sebas-Bot: Chat-Bot Sebas-Report: Intelligent Test Reports > Expansion of Karate Test Reports > Added Zipkin's trace ID to track Microservices > Rewrote report feature with Vue.js
prioritize targets to implement tests based on # of outages and impacts to users Became a Self-Organized/Self-Running Team Became as a Model Team With Guidelines and Reference Implementations Reduced Outages Dramatically (30 - 50 %)
Writing production codes may hurt the team Good to learn behavior of current products and teach members how to clarify requirements Writing test scripts don't hurt the team and can contribute to the team
