+# ResumeLens Backend Test Plan
+
+**Version:** 1.0
+**Date:** 2026-04-02
+**Purpose:** Comprehensive test plan for Go backend with specific test cases, inputs, and expected results

+  - **Trace:** Code quality
+
+- [ ] **Test 10.3.2: Non-JSON AI response**
+  - **Input:** Mock OpenAI returning plain text instead of JSON
+  - **Expected:**
+    - Parsing error
+    - Raw response included in error
+    - HTTP 500
+  - **Trace:** Code quality
+
+- [ ] **Test 10.3.3: Partial JSON response**
