Contract testing and integration testing are two sides of the same coin. Integration tests ensure that a consumer is calling a provider service correctly, whereas contract tests ensure that the provider service continues to meet its obligations to its consumers and that any changes are backward-compatible. These tests are also consumer driven. This means that the consumer submits a pull request to the provider's project to add these additional tests. The provider is not supposed to change these tests. If a contract test breaks, it implies that a backwards-incompatible change has been made. The provider has to make the change compatible and then work with the consumer team to create an upgrade roadmap.

Overview of this book
Cloud-native development is a modern approach to building and running applications that leverages the merits of the cloud computing model. With cloud-native development, teams can deliver faster and in a more lean and agile manner as compared to traditional approaches. This recipe-based guide provides quick solutions for your cloud-native applications.
Beginning with a brief introduction, JavaScript Cloud-Native Development Cookbook guides you in building and deploying serverless, event-driven, cloud-native microservices on AWS with Node.js. You'll then move on to the fundamental patterns of developing autonomous cloud-native services and understand the tools and techniques involved in creating globally scalable, highly available, and resilient cloud-native applications. The book also covers multi-regional deployments and leveraging the edge of the cloud to maximize responsiveness, resilience, and elasticity.
In the latter chapters you'll explore techniques for building fully automated, continuous deployment pipelines and gain insights into polyglot cloud-native development on popular cloud platforms such as Azure and Google Cloud Platform (GCP). By the end of the book, you'll be able to apply these skills to build powerful cloud-native solutions.
