What Users say about Specmatic

"Specmatic helped us build an executable deliverable based on the API Contract."

"Our earlier attempts made use of Postman mocks, but we soon realised that solves a slightly different problem. We saw some holes in the tool chain that we want and Specmatic covers that."

"Use Specmatic if you need to agree with another team about your shared expectations of the API. It's a well documented tool. It's straightforward to add to your build."

"It's an awesome tool! I'm a big fan of Specmatic and how it tackles contract testing because I'm a big fan of using the standard OpenAPI specification."

"Specmatic is addressing some real problems in an interesting way"

“Specmatic helped us achieve stable test environments by isolating dependencies through Smart Mocks”

Spec Driven Development: Beyond the first feature with API Design First

In my previous article, I shared my learnings experimenting with “API Design First with GitHub Spec Kit and Specmatic MCP” with OpenAPI specifications serving as API contracts. In this follow-up, I take things a step further to test how the setup holds up beyond the first feature. The focus here

Harness API Specifications as Executable Contracts

Specmatic supercharges your API Specifications by leveraging them as “Executable Contracts”. Specmatic does this by:

Intelligent Service Virtualization

Allows Consumer Application Development and Testing to progress independent of the Provider Application

API Specifications as Contract Tests

Generates Tests based on the API Specification File without you having to write any code

Try It Out →Learn More

Contract as Test

Tests for Free – Specmatic parses your API Specification files and based on this generates requests which are fired at your application. It then verifies if your application’s response is as per your API Specification. All this with a “No Code” approach.

Positive Tests

Verify if the API implementation meets basic criteria as per your API Specification

Negative Tests

Verify boundary conditions to identify error handling, unexpected behaviour, etc.

Try It OutLearn MoreTry It Out →Learn More

Contract as Mock

A component test setup should be able to isolate the “System Under Test” from its dependencies. Intelligent Service Virtuatlization enables you to achieve this by truly emulating the dependencies.

Intelligent Service Virtualization

Allows Consumer Application Development and Testing to progress independent of the Provider Application

Static and Dynamic Mocking

Expectations can be set either at startup or dynamically at runtime (for workflow testing) through an http endpoint

Try It Out →Learn More

Backward Compatibility

As API Specifcation authors / API designers it is important for us understand if our changes to existing APIs can break compatibility with existing API Consumers / Clients.

Specmatic can perform “Contract vs Contract” testing between two versions of your API Specification file and provide accurate results about backward compatibility breaking changes. Since this is a completely “No Code” capability, you do not have to write any code on the API Client or Service Applications.

Try It Out →Learn More

Treat Contract as Code

Specmatic promotes treating your API Specifications as code and storing them in a Version Control System where they truly belong.

Central Contract Repo

The “Single Source of Truth” for all your API Specifications so that stakeholders across the organization are on the same page.

Pull/Merge Request based Collaboration

Specmatic can help you identify backward compatibility breaking changes automatically as part of your pre-merge checks so that you can focus on API design.
