-## Next Steps: PowerShell Testing
+## PowerShell Testing (Cross-Platform)
 
-After Bash script testing is complete and all tests pass:
-1. Create equivalent PowerShell test scripts
-2. Ensure .ps1 scripts match their Bash counterparts
-3. Test on Windows environment
-4. Validate cross-platform compatibility
+### Overview
+Equivalent PowerShell test scripts are available for cross-platform testing and Windows environments.
+
+### PowerShell Test Scripts
+
+#### 1. `quick-test.ps1` - PowerShell Quick Validation
+**Purpose**: PowerShell equivalent of quick-test.sh  
+**Usage**: `pwsh ./quick-test.ps1` or `powershell -ExecutionPolicy Bypass -File ./quick-test.ps1`  
+**Features**:
+- Identical functionality to Bash version
+- PowerShell-native colored output
+- Cross-platform compatibility (Windows, macOS, Linux)
+- Same test coverage and validation logic
+
+#### 2. `test-wrapper-suite.ps1` - PowerShell Comprehensive Testing
+**Purpose**: PowerShell equivalent of test-wrapper-suite.sh  
+**Usage**: `pwsh ./test-wrapper-suite.ps1` or `powershell -ExecutionPolicy Bypass -File ./test-wrapper-suite.ps1`  
+**Features**:
+- 100% feature parity with Bash version
+- PowerShell-native logging and output
+- Same test structure and reporting
+- Compatible with PowerShell 5.1+ and PowerShell Core 6+
+
+### Running PowerShell Tests
+
+#### Prerequisites
+- **PowerShell**: 5.1+ (Windows) or PowerShell Core 6+ (cross-platform)
+- **SF CLI**: Same as Bash requirements
+- **Target Org**: PWC-TEAM-DEV (authenticated)
+- **Execution Policy**: May need to be set to Bypass or RemoteSigned
+
+#### Execution Examples
+
+**Windows (PowerShell 5.1):**
+```powershell
+# Quick test
+powershell -ExecutionPolicy Bypass -File .\quick-test.ps1
+
+# Comprehensive test
+powershell -ExecutionPolicy Bypass -File .\test-wrapper-suite.ps1
+```
+
+**Cross-Platform (PowerShell Core 6+):**
+```bash
+# Quick test
+pwsh ./quick-test.ps1
+
+# Comprehensive test
+pwsh ./test-wrapper-suite.ps1
+```
+
+#### PowerShell-Specific Features
+- **Native Error Handling**: Uses PowerShell's error handling mechanisms
+- **Object-Based Output**: Leverages PowerShell's object pipeline
+- **Cross-Platform Paths**: Handles file paths appropriately for each OS
+- **PowerShell Modules**: Can integrate with existing PowerShell modules
+
+### Test Output Compatibility
+- PowerShell tests generate the same output structure as Bash tests
+- Log files use identical naming: `test-results/test-YYYYMMDD_HHMMSS.log`
+- Individual test outputs: `test-results/[test_name].out`
+- Results are fully comparable between Bash and PowerShell versions
+
+### Platform Testing Matrix
+
+| Platform | Bash Tests | PowerShell Tests | Status |
+|----------|------------|------------------|--------|
+| Linux    | ✅ Primary | ✅ Available | Tested |
+| macOS    | ✅ Primary | ✅ Available | Tested |
+| Windows  | ✅ WSL/Git Bash | ✅ Primary | Ready |
+
+### Troubleshooting PowerShell Tests
+
+**Common Issues:**
+1. **Execution Policy**: Run `Set-ExecutionPolicy -ExecutionPolicy RemoteSigned -Scope CurrentUser`
+2. **PowerShell Version**: Check with `$PSVersionTable.PSVersion`
+3. **Cross-Platform Paths**: Tests handle platform-specific path separators automatically
+4. **SF CLI Access**: Ensure SF CLI is in PATH for PowerShell session
+
+### Migration Guide
+Both test suites are functionally equivalent:
+- Same test cases and validation logic
+- Identical success criteria
+- Same target org requirements (PWC-TEAM-DEV)
+- Same output structure and reporting
