+# Shell Script Validation Test Results
+
+**Test Date:** 2026-01-10
+**Subtask:** 5.2 - Verify shell script fails safely without PGPASSWORD
+
+## Test Overview
+
+This document verifies that the shell script `view_maturity_results.sh` properly validates the presence of the `PGPASSWORD` environment variable and provides clear error messages when it is not set.
+
+## Test Methodology
+
+### Test 1: Missing PGPASSWORD Environment Variable
+
+**Command:**
+```bash
+bash ./view_maturity_results.sh
+```
+
+**Expected Behavior:**
+- Script should detect missing PGPASSWORD
+- Display clear error message
+- Exit with non-zero status code
+
+**Actual Output:**
+```
+ERROR: PGPASSWORD environment variable is not set
+Please set it before running this script:
+  export PGPASSWORD='your_database_password'
+  ./view_maturity_results.sh
+```
+
+**Exit Code:** 1 ✅
+
+**Result:** ✅ PASS
+
+## Analysis
+
+### Error Message Quality
+
+The error message is **clear, actionable, and user-friendly**:
+
+1. **Problem Identification:** "PGPASSWORD environment variable is not set"
+2. **Solution Provided:** Shows exact command to set the variable
+3. **Usage Example:** Shows how to run the script after setting the variable
+4. **Security Context:** Script header includes CWE-798 warning
+
+### Code Implementation
+
+The validation check (lines 11-18 of view_maturity_results.sh):
+
+```bash
+# Check if PGPASSWORD is set
+if [ -z "$PGPASSWORD" ]; then
+    echo "ERROR: PGPASSWORD environment variable is not set"
+    echo "Please set it before running this script:"
+    echo "  export PGPASSWORD='your_database_password'"
+    echo "  ./view_maturity_results.sh"
+    exit 1
+fi
+```
+
+**Implementation Quality:**
+- ✅ Uses standard bash test `[ -z "$VAR" ]` to check for empty/unset variable
+- ✅ Exits with status 1 (error) to prevent script execution
+- ✅ Placed at the beginning of script (before any database operations)
+- ✅ Clear, multi-line error message
+- ✅ Provides actionable instructions
+
+### Security Improvements
+
+The script includes comprehensive security documentation:
+
+1. **Header Comments (lines 4-9):**
+   - Clear usage instructions
+   - Security warning about CWE-798
+   - Example of proper usage
+
+2. **No Hardcoded Credentials:**
+   - All 3 previous instances of `PGPASSWORD='NordaBiz2025Secure'` removed
+   - Now uses `$PGPASSWORD` environment variable
+   - Script fails fast if credentials not provided securely
+
+## Summary
+
+**Status:** ✅ ALL TESTS PASSED
+
+The `view_maturity_results.sh` script successfully:
+- ✅ Validates PGPASSWORD environment variable is set
+- ✅ Provides clear, actionable error messages
+- ✅ Exits with appropriate error code (1)
+- ✅ Includes comprehensive security documentation
+- ✅ No hardcoded credentials remain
+
+## Recommendations
+
+1. **Production Deployment:** Consider documenting the use of `.pgpass` file as an alternative to PGPASSWORD environment variable (more secure for automated scripts)
+2. **Additional Testing:** In production environment, verify the script works correctly when PGPASSWORD IS set
+3. **Documentation:** The docs/SECURITY.md file already includes comprehensive instructions for both PGPASSWORD and .pgpass configuration
+
+## Conclusion
+
+Subtask 5.2 is **COMPLETE**. The shell script properly validates credentials and provides excellent user feedback when credentials are missing.
