+# CCS Testing Requirements & Procedures
+
+**Version:** 2.1.4
+**Last Updated:** 2025-11-03
+**Status:** Active
+
+## Overview
+
+This document outlines the comprehensive testing requirements and procedures for the CCS (Claude Code Switch) project. Following these guidelines ensures consistent, reliable, and cross-platform compatible releases.
+
+## Test Suite Structure
+
+### Core Test Files
+
+| Test File | Purpose | Coverage | Platforms |
+|-----------|---------|----------|-----------|
+| `tests/uninstall-test.sh` | Uninstall functionality validation | 20 tests | Unix/Linux/macOS |
+| `tests/uninstall-test.ps1` | Uninstall functionality validation | 20 tests | Windows |
+| `tests/edge-cases.sh` | Comprehensive edge case testing | 37 tests | Unix/Linux/macOS |
+| `tests/edge-cases.ps1` | Comprehensive edge case testing | 37 tests | Windows |
+
+### Test Categories
+
+#### 1. Uninstall Functionality Tests (20 tests)
+**File:** `tests/uninstall-test.sh` / `tests/uninstall-test.ps1`
+
+**Sections:**
+1. **Empty Uninstall (3 tests)**
+   - Command executes without error
+   - Appropriate "nothing to uninstall" messaging
+   - Reports 0 items removed correctly
+
+2. **Install/Uninstall Cycle (5 tests)**
+   - Clean uninstall execution
+   - Removes ccs.md command file
+   - Removes ccs-delegation skill directory
+   - Preserves other commands (non-invasive)
+   - Preserves other skills (non-invasive)
+
+3. **Idempotency (2 tests)**
+   - Second uninstall succeeds
+   - Reports nothing found on subsequent runs
+
+4. **Output Formatting (4 tests)**
+   - Contains box-drawing headers
+   - Shows success messages
+   - Provides reinstallation instructions
+
+5. **Integration Tests (3 tests)**
+   - No profile errors on uninstall
+   - Version command still works
+   - Help command still works
+
+6. **Edge Cases (3 tests)**
+   - Partial installations handled
+   - Missing directories handled
+   - Error scenarios managed gracefully
+
+#### 2. Comprehensive Edge Cases (37 tests)
+**File:** `tests/edge-cases.sh` / `tests/edge-cases.ps1`
+
+**Coverage Areas:**
+- **Version Commands (3 tests)**
+- **Help Commands (2 tests)**
+- **Argument Parsing (6 tests)**
+- **Profile Commands (4 tests)**
+- **Error Handling (3 tests)**

+- **Configuration Validation (6 tests)**
+- **Real Usage Simulation (3 tests)**
+- **Platform-Specific Tests (4 tests)**
+
+## Testing Environment Requirements
+
+### Environment Variable Isolation
+
+**Critical Requirement:** All tests must use isolated HOME directories to prevent impact on user data.
+
+**Implementation Pattern:**
+```bash
+# Unix/Linux/macOS
+HOME=/tmp/test-ccs-home ./ccs --install
+HOME=/tmp/test-ccs-home ./ccs --uninstall
+
+# Windows PowerShell
+$env:HOME = "C:\temp\test-ccs-home"
+.\ccs.ps1 --install
+.\ccs.ps1 --uninstall
+```
+
+**Validation Requirements:**
+- ✅ Install uses test directory (not `~/.claude`)
+- ✅ Uninstall removes files from test directory only
+- ✅ Real user directories completely unaffected
+- ✅ Perfect test isolation achieved
+
+### Cross-Platform Compatibility
+
+**Platform-Specific Patterns:**
+- **Bash Version:** Uses `$HOME/.claude` directly
+- **PowerShell Version:** Uses HOME-first pattern with USERPROFILE fallback
+
+**PowerShell Pattern:**
+```powershell
+$HomeDir = if ($env:HOME) { $env:HOME } else { $env:USERPROFILE }
+```
+
+## Test Execution Procedures
+
+### Prerequisites
+
+1. **Clean Test Environment**
+   ```bash
+   # Remove any existing CCS installation
+   rm -rf ~/.ccs ~/.local/bin/ccs
+   ```
+
+2. **Required Tools**
+   - bash 3.2+ (Unix/Linux/macOS)
+   - PowerShell 5.1+ (Windows)
+   - Claude CLI 2.0.31+
+   - jq 1.6+ (optional, for JSON validation)
+
+### Running Tests
+
+#### Unix/Linux/macOS
+```bash
+# Navigate to CCS directory
+cd /path/to/ccs
+
+# Run uninstall tests
+./tests/uninstall-test.sh
+
+# Run edge case tests
+./tests/edge-cases.sh
+
+# Run all tests (full suite)
+./tests/uninstall-test.sh && ./tests/edge-cases.sh
+```
+
+#### Windows
+```powershell
+# Navigate to CCS directory
+cd C:\path\to\ccs
+
+# Run uninstall tests
+.\tests\uninstall-test.ps1
+
+# Run edge case tests
+.\tests\edge-cases.ps1
+
+# Run all tests (full suite)
+.\tests\uninstall-test.ps1; .\tests\edge-cases.ps1
+```
+
+### Expected Results
+
+**Success Criteria:**
+- **Total Test Pass Rate:** 100%
+- **Individual Test Suites:** Each must pass 100%
+- **Environment Isolation:** No impact on user data
+- **Cross-Platform Consistency:** Identical behavior across platforms
+
+**Sample Output:**
+```
+=== CCS Uninstall Test Results ===
+Total Tests: 20
+Passed: 20 (100%)
+Failed: 0 (0%)

+
+## Test Maintenance Procedures
+
+### When to Update Tests
+
+1. **New Features Added**
+   - Add corresponding test cases
+   - Update test documentation
+   - Validate cross-platform compatibility
+
+2. **Bug Fixes Implemented**
+   - Add regression tests for fixed bugs
+   - Verify fix doesn't break existing functionality
+   - Update test coverage metrics
+
+3. **Platform Changes**
+   - Test on new platform versions
+   - Update platform-specific test cases
+   - Validate compatibility
+
+### Test Review Process
+
+1. **Code Review Integration**
+   - Tests reviewed alongside code changes
+   - Ensure test coverage for new functionality
+   - Validate test quality and effectiveness
+
+2. **Release Validation**
+   - Full test suite execution before releases
+   - Cross-platform validation
+   - Performance benchmarking
+
+## Troubleshooting Test Failures
+
+### Common Issues
+
+1. **Environment Variable Conflicts**
+   - **Symptom:** Tests affecting user directories
+   - **Solution:** Verify HOME isolation pattern
+   - **Prevention:** Always use isolated test environments
+
+2. **Permission Issues**
+   - **Symptom:** File operation failures
+   - **Solution:** Check file permissions and paths
+   - **Prevention:** Validate prerequisites before testing
+
+3. **Platform-Specific Failures**
+   - **Symptom:** Tests pass on one platform, fail on another
+   - **Solution:** Review platform-specific code paths
+   - **Prevention:** Test on all supported platforms
+
+### Debug Procedures
+
+1. **Enable Verbose Output**
+   ```bash
+   # Add debug flags to test scripts
+   ./tests/uninstall-test.sh --verbose
+   ```
+
+2. **Isolate Failing Tests**
+   ```bash
+   # Run individual test sections
+   ./tests/uninstall-test.sh --section=empty-uninstall
+   ```
+
+3. **Validate Environment**
+   ```bash
+   # Check environment variables
+   echo "HOME: $HOME"
+   echo "USERPROFILE: $USERPROFILE"
+   ```
+
+## Best Practices
+
+### Test Development Guidelines
+
+1. **Test Isolation**
+   - Never modify user data during tests
+   - Use temporary directories for all file operations
+   - Clean up all test artifacts
+
+2. **Cross-Platform Considerations**
+   - Test on all supported platforms
+   - Use platform-agnostic patterns where possible
+   - Handle platform-specific differences explicitly
+
+3. **Maintainability**
+   - Clear test documentation
+   - Consistent test structure
+   - Reusable test utilities
+
+### Continuous Improvement
+
+1. **Test Coverage Analysis**
+   - Regular coverage assessment
+   - Identify untested code paths
+   - Prioritize high-risk areas
+
+2. **Performance Monitoring**
+   - Track test execution times
+   - Identify performance regressions
+   - Optimize slow test cases
+
+3. **Quality Metrics**
+   - Monitor test pass rates
+   - Track bug detection rates
+   - Measure test effectiveness
