From 7e881f6565293585b7c42c4d4b477a87c0fd5ae1 Mon Sep 17 00:00:00 2001 From: Snider Date: Thu, 29 Jan 2026 19:48:21 +0000 Subject: [PATCH] test(mcp): add comprehensive Quota System tests (P2-016) Add extensive Pest tests for the MCP quota system covering: - Usage recording and tracking (tool calls, tokens) - Quota enforcement per tier (free, starter, pro, business, enterprise) - Token quota enforcement independently of tool calls - Detailed quota check responses with reasons - Remaining quota calculation - Quota reset and monthly period management - Usage history retrieval - Quota HTTP headers (X-MCP-Quota-*) - Quota limits retrieval and caching - CheckMcpQuota middleware (429 responses, headers injection) - Workspace-scoped quotas (isolation, independent limits) - McpUsageQuota model (scopes, accessors, static methods) - Edge cases (concurrent requests, cache invalidation, month boundaries) - Cache management (performance caching, invalidation) Replaces basic test coverage with ~100 test cases for thorough validation.
