From 8c252200056ca5318df885794f18776311bf56a3 Mon Sep 17 00:00:00 2001 From: DevSolex Date: Wed, 15 Jul 2026 23:17:19 +0100 Subject: [PATCH 1/2] =?UTF-8?q?feat(#279):=20add=20cross-language=20contra?= =?UTF-8?q?ct=20test=20backend=20=E2=86=94=20AI=20service=20schemas?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Implements issue #279 (backlog item #71). New files: - app/backend/scripts/openapi-validate.ts Shared helpers to fetch the AI service OpenAPI document, resolve $refs, and structurally validate a plain object against a schema. Also runnable as a standalone CLI for quick spec drift checks. - app/backend/test/contract/ai-service.contract.spec.ts Contract test that: • Obtains the AI service OpenAPI spec (live fetch when AI_SERVICE_URL is set; falls back to an embedded snapshot so CI always runs). • Asserts all six v1 endpoints the backend depends on exist in the spec. • Verifies provider_preference and TaskStatus enum values. • Checks required fields on every response schema against the TypeScript interfaces the backend compiles against. • Validates real AI service fixture payloads (app/ai-service/fixtures/) against those schemas — catching enum drift or missing fields before they reach production. • Compile-time type guards ensure backend interfaces stay in sync with the schema shapes (fails the build on shape divergence). --- app/backend/scripts/openapi-validate.ts | 222 +++++++ .../test/contract/ai-service.contract.spec.ts | 569 ++++++++++++++++++ 2 files changed, 791 insertions(+) create mode 100644 app/backend/scripts/openapi-validate.ts create mode 100644 app/backend/test/contract/ai-service.contract.spec.ts diff --git a/app/backend/scripts/openapi-validate.ts b/app/backend/scripts/openapi-validate.ts new file mode 100644 index 00000000..877631db --- /dev/null +++ b/app/backend/scripts/openapi-validate.ts @@ -0,0 +1,222 @@ +/** + * openapi-validate.ts + * + * Utilities for fetching and structurally validating the AI service OpenAPI + * document.

Allowed unused vars must match /^_/u SchemaObject was imported but never referenced in the test file. Removing it is the clean fix — it can be re-added with an _ prefix if it becomes needed in future. --- app/backend/test/contract/ai-service.contract.spec.ts | 1 - 1 file changed, 1 deletion(-) diff --git a/app/backend/test/contract/ai-service.contract.spec.ts b/app/backend/test/contract/ai-service.contract.spec.ts index c1acc017..57f4e6cf 100644 --- a/app/backend/test/contract/ai-service.contract.spec.ts +++ b/app/backend/test/contract/ai-service.contract.spec.ts @@ -19,7 +19,6 @@ import { getResponseSchema, validateAgainstSchema, OpenApiDocument, - SchemaObject, } from '../../scripts/openapi-validate'; // ─── 1.
