## Prototype your design! Robert Griesemer dotGo 2016, Paris ## Getting to good software design • Literature is full of design paradigms • Usually involves ○ Design docs Feedback from reviewers • Often a “dry” exercise ☐ No software is created until design is “completed” ## How can we tell if we have a good design? ## Elsewhere, design thinking requires prototyping Try stuff Reframe problems mutation Define appropriate methods on that type A Go implementation allows us to explore our design. ## Key missing feature: Nice notation ### The work-around, accessor methods for multi-dim. index

Design Patterns are reusable elements of design that may help aid in making software more maintainable, flexible, and extensible. The term 'design patterns' can be traced Four' book Design Patterns, in which common software design patterns were defined and categorized. In this talk, you will learn the fundamentals of the creational, structural, and behavior design patterns

Istio for Creating API Tests Low Effort API Testing for Microservices ## mesh dynamics ## Structure ## • What has changed? – Migration to microservices triggering need for extensive API tests ## • Problem: Problem: – Creating API tests is effort intensive — Creating + maintainting E2E, service tests, component tests adds up very quickly • What happens if you do not address the problem? — Thorough test coverage • 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
