Contract Testing in Action: With Pact, Pactflow, and Github Actions

Bol

Contract testing is a simple, reliable way to make sure that each service and API plays nice with other components so you can deploy independently and safely. From the back cover: Contract Testing in Action is a hands-on guide to contract testing for microservices applications and other systems of loosely-coupled components. After learning the basics of contract design and implementation, you'll dive into constructing your own contract testing framework. You'll explore the leading contract testing tools, including Pact, PactFlow, and GitHub Actions. Plus, you'll set up consumer-driven contract testing for REST and GraphQL APIs and learn to integrate contract testing into a CI/CD pipeline. Finally, you'll delve into provider-driven contract testing, which simplifies adoption by utilizing your existing stack and practices. About the reader: For experienced software developers and quality engineers who have worked with Java, JavaScript, and APIs. Contract testing is a simple, reliable way to make sure that each service and API plays nice with other components so you can deploy independently and safely.In a microservices-first world, traditional testing struggles to keep up with all the potential interactions in a large, loosely-coupled system. Contract testing checks the compatibility of an API or service by validating it against an agreed contract. This straightforward method uncovers integration issues early and adds valuable transparency to compatibility expectations.In Contract Testing in Action you'll learn: The core concepts and practices of contract testing Testing microservices with Pact Consumer-driven and bi-directional testing Building a contract testing framework Converting API integration tests to contract tests Contract Testing in Action introduces the practice of contract testing through engaging hands-on examples. You'll learn how to introduce contract tests for multiple different types of communication, from REST APIs to GraphQL. By the end of this practical guide, you'll be comfortable with advanced contract testing concepts like can-i-deploy, provider states, and webhooks. You'll even get tips on how to introduce contract testing to your team and other business stakeholders.
