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.
