From 8a2950ace3302e308b8c4c32dcfe1aab0259bae4 Mon Sep 17 00:00:00 2001 From: LeonardoBai12 <69223422+LeonardoBai12@users.noreply.github.com> Date: Mon, 22 Jun 2026 01:44:53 -0300 Subject: [PATCH 1/9] Add mapper test scenarios and fix null String bug Expand MapperServiceImplTest with new scenarios covering Double/Boolean type mapping, root-level fields without parents, non-200 status code preservation, multiple parent levels, null String omission with ignoreEmptyValues, and concatenated fields with empty values. Add supporting helpers to RegularHelper, ConcatenatedHelper, and HelperWithoutEmptyValues (ignoreEmptyValues param on getConcatenatedMappingRule, expectedMeasuredResponseWithEmptyValues, flat/deep-nested response factories). Fix MapperServiceImpl.transformValue: the String branch was calling .jsonPrimitive.content on JsonNull, producing the literal string "null" instead of JsonNull, bypassing the null-filter in mapOldResponse.

Fix auth header isolation: ServerServiceImpl now filters Authorization from captured request headers so the Middleware's own JWT/Basic auth is never forwarded to the external API. ClientExtensions skips Authorization when iterating headers so OriginalRoute.authHeader always takes priority over any Authorization value in preConfiguredHeaders. Expand ClientServiceImplTest with 8 new scenarios: Bearer/Basic/null auth header forwarding, Head HTTP method verification, empty preConfiguredHeaders/Queries/Body fallback to originalRoute values, and authHeader priority over conflicting headers. Expand ServerServiceImplTest with 6 new scenarios: unauthorized request returns 401, multiple custom headers forwarded, Authorization not forwarded to handler, MiddlewareException and IllegalArgumentException handling on mapping/routes routes.
