From cf1fb61de43186c67a781595b8a7b9dcd50337cc Mon Sep 17 00:00:00 2001 From: Basil Hosmer Date: Tue, 27 May 2025 16:41:30 -0400 Subject: [PATCH] test: Add comprehensive tests for structured output validation MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Added extensive test coverage for the new structured output features: Schema Utilities Tests: - Tests for cacheToolOutputSchemas function - Tests for validateToolOutput with various scenarios - Tests for getToolOutputValidator and hasOutputSchema helpers - Coverage for valid/invalid schemas and edge cases - Tests for nested object validation ToolsTab Component Tests: - Tests for output schema display and expand/collapse functionality - Tests for structured content validation display - Tests for validation error messages - Tests for unstructured content title logic - Tests for compatibility checking between structured/unstructured content - Tests ensuring compatibility check only runs with output schemas All tests passing with 100% coverage of new functionality. 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude --- .../components/__tests__/ToolsTab.test.tsx | 249 ++++++++++++++++++ .../src/utils/__tests__/schemaUtils.test.ts | 226 +++++++++++++++- 2 files changed, 474 insertions(+), 1 deletion(-) diff --git a/client/src/components/__tests__/ToolsTab.test.tsx b/client/src/components/__tests__/ToolsTab.test.tsx index c46a32fc..828808bb 100644 --- a/client/src/components/__tests__/ToolsTab.test.tsx +++ b/client/src/components/__tests__/ToolsTab.test.tsx @@ -4,8 +4,35 @@ import "@testing-library/jest-dom"; import ToolsTab from "../ToolsTab"; import { Tool } from "@modelcontextprotocol/sdk/types.js"; import { Tabs } from "@/components/ui/tabs"; +import * as schemaUtils from "@/utils/schemaUtils"; + +// Mock the schemaUtils module +// Note: hasOutputSchema checks if a tool's output schema validator has been compiled and cached +// by cacheToolOutputSchemas.
