From 4ba240c0624dda8ab436ae5693d2d9456fa57302 Mon Sep 17 00:00:00 2001 From: James Bland Date: Thu, 27 Nov 2025 19:55:33 -0500 Subject: [PATCH] test: fix failing tests and expand coverage to 72.56% MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Fixed 3 failing tests by adding explicit serde rename attributes to PricingOperation enum fields for camelCase JSON deserialization. Added comprehensive test coverage: - models.rs: 98.55% line coverage (25 -> 35 tests) - db.rs: 73.70% line coverage (14 -> 22 tests) - main.rs: 32.63% line coverage (0 -> 7 tests) Total coverage improved from 56.35% to 72.56% lines. Test additions: - All PricingOperation variants (Get, Put, ListCommon, IncrementAccess) - Reserved and Spot pricing serialization - Complex pricing data with all optional fields - Edge cases for parsing, expiration checks, and key building - HTTP vs MCP request detection logic - Path parameter extraction and validation Remaining uncovered code is primarily async AWS SDK interactions which require integration tests with mocked DynamoDB.
