Are microservices driving you crazy?
Naresh Jain's talk at YOW 2023 focused on the main benefits of contract-driven development (CDD) with the use of Specmatic, an open-source tool he co-created.
He highlights that CDD is essential for organizations with a large number of microservices to ensure all services are properly integrated and working harmoniously before deployment.
He demonstrates how CDD can speed up deployment times and enable independent and parallel development across teams, a crucial factor in agile microservices ecosystems. Besides testing for compatibility and eliminating integration surprises, Specmatic facilitates visualizations of service dependencies and API coverage, further aiding in maintaining a good system architecture.
Specmatic supports testing and development with OpenAPI, AsyncAPI, and SOAP specifications (more on the way). By leveraging Specmatic in CI pipelines, companies can programmatically ensure that all contracts are honored before accepting pull requests, therefore embedding contract validation into the heart of the development workflow.
The video highlights the power of Specmatic in intelligent service virtualization, automated test generation from specifications, and implementing fault injection scenarios through examples—all without writing additional code.
Embrace contract-driven development with tools like Specmatic offers the promise of more robust, predictable, and efficient software delivery cycles.
