We’ve decided to bring consumer-driven contract testing back from the archive for this edition even though we had allowed it to fade in the past. The concept isn’t new, but with the mainstream acceptance of microservices, we need to remind people that consumer-driven contracts are an essential part of a mature microservice testing portfolio, enabling independent service deployments. But in addition, we want to point out that consumer-driven contract testing is a technique and an attitude that requires no special tool to implement. We love frameworks like Pact because they make proper contract tests easier to implement in certain contexts. But we have noticed a tendency for teams to focus on the framework rather than on the general practice. Writing Pact tests is not a guarantee that you are creating consumer-driven contracts; likewise, in many situations you should be creating good consumer-driven contracts even where no pre-built testing tool exists.

When two independently developed services are collaborating, changes to the supplier’s API can cause failures for all its consumers. Consuming services usually cannot test against live suppliers since such tests are slow and brittle, so it’s best to use Test Doubles, leading to the danger that the test doubles get out of sync with the real supplier service. Consumer teams can protect themselves from these failures by using integration contract tests – tests that compare actual service responses with test values. While such contract tests are valuable, they are even more useful when consuming services provide these tests to the supplier, who can then run all their consumers’ contract tests to determine if their changes are likely to cause problems – adopting consumer-driven contracts. Such consumer-driven contract tests are an essential part of a mature microservice testing portfolio.
