Polyglot — Custom In-House Test Framework

Polyglot is a custom in-house test framework built on a polyglot stack rather than a single toolchain, so that a polyglot microservice estate can be exercised from one place. Each service language keeps its native runner — Go, xUnit.net, pytest — while the harness itself is implemented across the same stack and owns what those runners cannot: one command to select, run, and aggregate suites across languages, provisioning shared service-level fixtures and dependencies, and emitting a single report and a single exit code that CI can gate on. The goal is a test story that does not fragment at every language boundary.
