Consumer-driven Contracts is an approach to testing integration between services. In a distributed system, many components talk to each other. Typically via request/response protocols or message queues. The client must know and understand the API provided by the server. What kind of endpoints are available, what formats, request/response schema. Without consumer-driven contracts (CDC for short), we are often reckless when it comes to testing. Maybe we have a bunch of smoke tests against a mocked server. Maybe we copy-paste typical responses from the server’s documentation. But both client and server can evolve, breaking the integration in unexpected ways. CDC attempts to codify the API without explicit schema and coordination.

Jest to odcinek podkastu:
Around IT in 256 seconds
Podcast for developers, testers, SREs... and their managers. I explain complex and convoluted technologies in a clear way, avoiding buzzwords and hype. Never longer than 4 minutes and 16 seconds. Because software development does not require hours of lectures, dev advocates' slide decks and hand waving. For those of you, who want to combat FOMO, while brushing your teeth. 256 seconds is plenty of time. If I can't explain something within this time frame, it's either too complex, or I don't understand it myself.
