"By utilizing contract testing, we can establish a systematic workflow to make the process enforceable and detect compatibility issues early."

"Contract testing promotes the idea of isolated unit tests against the integration point based on a predefined contract rather than a real end-to-end interaction, making it comparatively fast and stable."

"We believe contract testing is valuable for testing integration points in microservices architecture and can help evolve services with confidence."

Atlassian: Jira

"A project with a tight deadline (8 weeks), external customers, and a lot of "unknown unknowns", led us to one overarching driver: we needed to move quickly, and iterate on our API fast as we received feedback from our external customers. The team moved to a specification-first approach, meaning APIs were documented, codified in tests and shared with all parties."
