name: Test Specifications
description: Documentation that defines the requirements, procedures, and expected outcomes for testing software systems and
  APIs. Test specifications establish the criteria that implementations must satisfy, bridging the gap between product requirements
  and executable test cases. They include test plans, test case definitions, acceptance criteria, and conformance requirements.
  Effective use of this practice reduces bugs in production, supports contract testing, and enables a culture of quality-driven
  development aligned with OpenAPI, AsyncAPI, and JSON Schema standards.

- name: OpenAPI Initiative
  description: The OpenAPI Specification (OAS) is the de-facto standard for describing RESTful APIs. OpenAPI documents serve
    as machine-readable test specifications that tools such as Dredd, Schemathesis, and Postman use to auto-generate and validate
    test suites against live API implementations.

- name: AsyncAPI Initiative
  description: AsyncAPI is an open specification standard for event-driven and message-based APIs. AsyncAPI documents define
    the channels, messages, and schemas of asynchronous interfaces, providing a test specification baseline for contract and
    integration testing of Kafka, WebSocket, AMQP, and MQTT APIs.

- name: JSON Schema
  description: JSON Schema provides a vocabulary for annotating and validating JSON documents. Used extensively as the payload
    specification layer in test specifications, JSON Schema enables both human-readable documentation and machine-executable
    validation of API request and response bodies.

- name: Gherkin / Cucumber BDD
  description: Gherkin is a plain-text language used to write behavior-driven test specifications in Given-When-Then format.
    Cucumber and Karate consume Gherkin feature files as executable test specifications that bridge business requirements
    and automated test implementation for API testing.

- name: Pact Contract Testing
  description: Pact is a consumer-driven contract testing tool where consumers write test specifications (pacts) that define
    what responses they expect from provider APIs. Providers then verify their implementation satisfies all consumer-authored
    specifications via the Pact Broker.

- name: Swagger Editor
  description: Swagger Editor is an open-source web-based editor for designing OpenAPI specifications that double as test
    specifications. It provides real-time validation, mock server generation, and exportable spec files that integrate with
    testing pipelines.

- name: Optic API
  description: Optic is a developer tool that uses API specifications as the source of truth for testing. It tracks specification
    changes, generates changelog diffs, and validates live traffic against OpenAPI specs to detect contract drift between
    specifications and implementations.
