From e96025cade28b330cf187f1079ec0238417dcf93 Mon Sep 17 00:00:00 2001 From: jedarden Date: Thu, 2 Jul 2026 18:58:00 -0400 Subject: [PATCH] test(bf-1ht4): verify test request builder functions Add comprehensive test coverage for all request builder helper functions in helpers_test.go. The new test file verifies: 1. CreateProxyRequest() - correct method, URL, headers, and body handling 2. CreateMessagesRequest() - POST /v1/messages requests 3. CreateStreamingRequestBody() - valid streaming JSON with stream:true 4. CreateNonStreamingRequestBody() - valid non-streaming JSON 5. CreateStreamingMessagesRequest() - streaming requests 6. CreateNonStreamingMessagesRequest() - non-streaming requests 7. CreateTestRequestBody() - custom request bodies with model/messages/stream 8. MustCreateTestRequestBody() - panic behavior on error All 33 sub-tests pass, confirming that the request builder functions create valid HTTP requests with correct structure, headers, and bodies for both streaming and non-streaming scenarios.
