chai-json-schema

Chai plugin for validating values against JSON Schema v4. Current stable version 1.5.1, maintained as a legacy plugin using Tiny Validator tv4 for schema validation. Supports draft-04 only, with no support for later drafts. Key differentiator: provides BDD and TDD assertions directly in Chai tests. Release cadence is low; last release was 2019. Consider chai-json-schema-ajv for newer JSON Schema versions.
