DIY (Do-it-Yourself) Testing
summary
The drivers team builds a language-agnostic test system: a YAML test format and reusable harnesses that run unit tests (mocked server responses) and integration tests against real clusters created by Mongo Orchestration, a Python REST service that starts MongoDB processes and blocks until replica sets are ready. Ten official drivers share the same tests, enabling multi-version testing, reproducing failover scenarios, eliminating version-specific startup logic, and materially reducing cross-driver inconsistencies.
