# 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.
