The end of the year is nearly upon us and we have lots to celebrate! Specmatic just turned 4 and the release of version 1.0 of Specmatic this month, was an exciting milestone to achieve. We have rolled out many compelling new capabilities this year and there is much more to come!

In this issue:

Conference appearances

The team has presented at several conferences this year including Agile India 2023, YOW in Australia and AsyncAPI on Tour in Bangalore plus many smaller Meetups. They’ve been spreading the word about the benefits of CDD and how Specmatic can help make it all happen.

Look inside your microservices implementation with Specmatic Insights

Specmatic Insights is a new tool that aggregates Specmatic reports from various environments such as your CI/CD pipelines, and visualizes how your organization’s microservices talk to each other, providing actionable insights.

Contract testing made even easier with VSCode extension

The new Specmatic VSCode extension makes it easy to set up and run your contract tests from within VSCode. An interactive UI takes care of your configurations for running contract tests and remembers your settings for future tests. It can also automatically generate examples and test data for your OpenAPI specifications using GPT-4.

Word is getting out!

This year, others have been picking up on the benefits of Contract Driven Development and how Specmatic facilitates a CDD workflow.

In March, InfoQ published an article outlining an organization’s Contract-Driven Development adoption journey. It covers off the many benefits of CDD as well as how the organization overcame some of the challenges.

A man is pointing to the Specmatic tool for easy microservice testing, featured on Dave Farley's Continuous Delivery channel.

Dave Farley posted a video on “Easy Microservice Testing” with Specmatic to his Continuous Delivery YouTube channel which sparked some lively conversation.

Serghei Lakovlev has created a handy action to set up a Specmatic environment for use in Github actions.

Markus Oberlehner discovered the benefits of stubbing endpoints with Spermatic and shared his thoughts on YouTube.

Geovanny Ribeiro shared on LinkedIn when he discovered he could stub http APIs with their OpenAPI specifications and mock a Kafka broker with AsyncAPI specification.

Specmatic explainer videos

This year we’ve produced a series of videos to help people understand the benefits of Contract-Driven Development and how Specmatic works. You’ll find them on the Specmatic website and on our YouTube channel.
