"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."

"By switching to contract testing we now have confidence that any service we deploy will always be compatible with the things it needs to connect with"

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."
