Summary

In this chapter, we did a deep dive into contract testing. You learned about what a contract is and how you can use it. You then learned about the two different approaches to contract testing, where it can either be consumer-driven or provider-driven. In addition to coming to a thorough understanding of the theory of contract testing, you learned how to use Postman to set up these kinds of tests. You also learned how to create a collection designed for contract testing.

I also showed you how to think about the tests that you add to a contract testing request and how to set up and use the Postman Interceptor, which lets you figure out which requests and inputs it makes sense to include in a contract test suite. I also showed you how to share contract tests in Postman so that they can be run and fixed in ways that embrace the usefulness of this testing technique.

With this under your belt, in the next chapter, we are going to put everything you have learned together into...
