Step	Title	Concept Covered	Learning objectives	Further Reading
step 1	Create our consumer before the Provider API even exists	Consumer-driven design	Understand use case	https://martinfowler.com/articles/consumerDrivenContracts.html
step 2	Write a unit test for our consumer	-	How to write a basic unit test for an HTTP Client Understand how a unit test is unable to catch certain integration issues	https://docs.pact.io/faq/convinceme
step 3	Write a Pact test for our consumer	Consumer side pact test	Understand basic Consumer-side Pact concepts Understand "Matchers" to avoid test data brittleness Demonstrate that Pact tests are able to catch a class of integration problems	https://docs.pact.io/5-minute-getting-started-guide#scope-of-a-consumer-pact-test https://docs.pact.io/best_practices/consumer
step 4	Verify the consumer pact with the Provider API	Provider side pact test	Understand basic Provider-side Pact concepts Place provider side testing in a broader testing context (e.g. where it fits on the pyramid)	https://docs.pact.io/5-minute-getting-started-guide#scope-of-a-provider-pact-test
step 5	Fix the consumer's bad assumptions about the Provider	Humans talking to humans (collaboration)	Understand that a tool facilitates collaboration, it doesn't replace it
step 6	Write a pact test for 404 (missing User) in consumer	Testing API invariants	Understand how we can test "stateful" APIs without having to create complex, sequential API calls
step 7	Update API to handle 404 case	Provider States	How Pact deals with "stateful" interactions, via the concept of "Provider States"	https://docs.pact.io/getting_started/provider_states
step 8	Write a pact test for the 401 case	Testing authenticated APIs	Service evolution - adding a new feature
step 9	Update API to handle 401 case	Service evolution	Understand the challenge of dealing with complex/dynamic data, such as time-bound authentication tokens
step 10	Fix the provider to support the 401 case	Request filters	Understand Pact's approach to dealing with complex/dynamic data, such as time-bound authentication tokens
step 11	Implement a broker workflow for integration with CI/CD	Automation	Understand how to use Pact in a CI and CD workflow	https://docs.pact.io/pact_broker https://docs.pact.io/best_practices/pact_nirvana
