After setting up our consumer tests, we need a way to verify our contract against our provider service. Fortunately, Pact has an in-built Verifier than can match up a instantiated Provider state with what our contract expects of it. We simulate our Consumer request to the Provider, and we alter our Provider state in regards to what should be returned when a certain endpoint is hit. It is important that we discard and clean up all of our testing states after our Pact Verification has concluded. This slideshow gives a visual example of the verification system that is used on Pact consumer-generated contracts.

Next Steps

We need to find and/or create good resources for developers to quickly learn how and when to use Pact. Usage will remain limited until we can get many developers to view contract tests as just another standard quality assurance tool to use alongside other kinds of automated tests when appropriate. Potential resources will be collected in a child page for review and curation.
