Contract Testing Google Pub/Sub: Using AsyncAPI specs as Executable Contracts

Shift-Left the identification of integration issues in applications built with Event Driven Architecture (EDA) by leveraging AsyncAPI specs as Executable Contracts Introduction The surge in popularity of microservices has revolutionized the way we think about software architecture. However, as systems grow and inter-service communication increases, the risk of integration issues can also rise. One such

Introduction to Contract Driven Development with Specmatic

Transcript Hi, welcome to this demo of contract-driven development where I’m going to use Specmatic, an open-source tool to turn your API specification into executable contracts. We have an app which sends a request to a BFF, a backend for frontend, which in turn sends a request to a domain service. Notice you could have

Specmatic API Coverage Report

Early detection of mismatches between your API specs and implementation: Exploring Specmatic’s API Coverage Report

Specmatic’s API coverage report helps identify any mismatches between an OpenAPI specification and an application’s endpoints early in the development lifecycle. The report lists all the endpoints, their coverage, and indicates if they are missing in the spec or not implemented in the application. You can define success criteria for the API coverage report and fix issues.

JDBC stubbing with Redis and Specmatic contract testing.

Break the Chains of Database Dependencies: Leveraging Specmatic for JDBC Stubbing

With Specmatic JDBC stub, you can easily test APIs without the need for a complex database setup. By switching out the real database with a Specmatic JDBC stub, we can set expectations for the stub to respond to specific queries. These expectations can be recorded based on actual interactions. Once the expectations are set, we no longer need the database for our tests!
