Look inside

You’re a senior developer at Travel World Agency (TWA). Its swift success has come with a high rise in computing costs. But before it introduces potentially disruptive cost-saving modifications to its next-gen system running on Amazon Web Services (AWS), it needs to improve the quality of its microservices architecture. Your job is to create API and performance testing using Karate and Gatling and apply a black-box approach that prevents anyone from changing what’s inside the microservices. You’ll test the connection with external services as well as with a database, then create a performance test with minimal configuration by reusing one of your API tests.

This project is designed for learning purposes and is not a complete, production-ready application or solution.
