Let me first check what this task involves by looking at the current task details. --- --- I can see that task 23.3 is "Develop Unit Tests for Middleware Components" which focuses on writing unit tests for middleware components including authentication, rate limiting, input validation, and error handling middleware. Let me first examine the current middleware structure to understand what needs to be tested: --- <details> <summary>Listed directory src/middleware • **9** results</summary> | Name | |-------| | 📁 `__tests__` | | 📄 `security.ts` | | 📄 `api-key-auth.ts` | | 📄 `validation.ts` | | 📄 `rateLimiter.ts` | | 📄 `rateLimiter.example.ts` | | 📄 `index.ts` | | 📄 `sanitization.ts` | | 📄 `error-handler.ts` | </details> --- Now let me check what tests already exist in the middleware __tests__ directory: --- <details> <summary>Listed directory src/middleware/__tests__ • **4** results</summary> | Name | |-------| | 📄 `error-handler.test.ts` | | 📄 `security.test.ts` | | 📄 `rateLimiter.test.ts` | | 📄 `validation.test.ts` | </details> --- Let me also check if there are any missing test files by comparing with the middleware files: --- Read file: src/middleware/api-key-auth.ts --- Read file: src/middleware/sanitization.ts --- --- Now let me check which middleware components don't have test files yet: --- <details> <summary>Searched codebase "api-key-auth.test.ts" • **0** results</summary> No results found </details> --- <details> <summary>Searched codebase "sanitization.test.ts" • **0** results</summary> No results found </details> --- Based on my analysis of the middleware directory, I can see that we have several middleware components but some are missing unit tests. Let me identify what needs to be tested and create the missing test files. From the middleware directory, I found: - `api-key-auth.ts` - No test file yet - `sanitization.ts` - No test file yet - `security.ts` - Has test file ✓ - `validation.ts` - Has test file ✓ - `rateLimiter.ts` - Has test file ✓ - `error-handler.ts` - Has test file ✓ Let me start by creating comprehensive unit tests for the `api-key-auth.ts` middleware: --- Cancelled --- --- Let me create the unit test file for the API key authentication middleware: --- Cancelled --- --- Let me try a different approach and create the test file: --- Cancelled --- --- Let me update the task progress and create the necessary test files for the middleware components: --- --- --- --- Now let me create the comprehensive unit test file for the API key authentication middleware: --- Cancelled --- --- _**User**_ continue --- _**Assistant**_ --- Okay, I'll continue. I will now create the test file for `api-key-auth.ts`. --- ```diff - + import { Request, Response, NextFunction } from 'express'; + import { apiKeyAuth, AuthenticatedRequest, requireScopes, requireReadAccess, requireWriteAccess, requireAdminAccess, optionalApiKeyAuth, isAuthenticated, getApiKeyInfo } from '../api-key-auth';

Changing `tools: { call: undefined }` to `tools: {}` in one test to avoid the explicit `undefined`. 2.
