Title: Behavior-driven Tests for Microservices-based Algo Trading System ## Summary: Introduction: This poster will introduce a test framework we use at Bloomberg to enable behavior-based tests in natural often non-trivial to automate the system-level tests with external dependencies. Controlling external dependencies are especially important for algo tests since certain algo behaviors require hard-to-produce condition. - Fully automated: Running tests are integrated into CI so also behaviors are regressed for any dependent code change. - Natural language layer: Tests are written in natural language so they

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 outcome: Just create E2E 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
