SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Pin consumer expectations for API surfaces by generating and validating contract tests to prevent breaking changes.

Core Features & Use Cases

  • Identify boundaries and consumer sets to pin interfaces and prevent drift.
  • Generate concrete contract test cases and a transferable schema for CI integration.
  • Provide an end-to-end workflow from boundary discovery through test generation to documentation and evidence-led outputs.

Quick Start

Provide a boundary and consumer list, and generate a contract-test plan with sample cases and required outputs.

FAQPage Schema
How do I generate contract tests for an API to prevent breaking changes?

Generate contract tests by identifying API boundaries and consumer sets, then producing concrete test cases and a transferable schema to pin consumer expectations and prevent drift.

What is API contract testing and when do I need it for my interfaces?

API contract testing validates that consumer expectations are preserved across boundaries. You need it for REST, GraphQL, gRPC, messaging interfaces, and file formats to prevent breaking changes.

Can I use contract testing for GraphQL and gRPC boundaries, or is it limited to REST?

Contract testing applies to GraphQL and gRPC boundaries alongside REST. It also supports messaging interfaces and file formats where consumer expectations must be preserved.

How do I wire contract tests into CI with documentation outputs?

Wire contract tests into CI by generating a transferable schema and test cases from your boundary and consumer list, producing documentation and evidence-led outputs for the pipeline.

What's the best way to identify boundaries and consumers before generating contract cases?

Identify boundaries and consumers by mapping your API surfaces and their consumer sets, then provide this list to generate a contract-test plan with sample cases and required outputs.

Why does contract test generation require a defined consumer list to pin interfaces?

Contract test generation requires a defined consumer list to pin interfaces because it captures specific consumer expectations, preventing drift by validating those surfaces against generated cases.
