nu_plugin_secret 0.7.0

Production-grade secret handling plugin for Nushell with secure CustomValue types that prevent accidental exposure of sensitive data
Documentation
# Nushell Integration Tests for nu_plugin_secret

This directory contains comprehensive Nushell script tests that complement the existing Rust unit tests by validating the plugin in real Nushell environments.

## 🎯 Phase 6.1 Foundation - COMPLETED ✅

### Key Components Implemented

#### 1. **Test Framework (`runner.nu`)**
- Comprehensive test runner with parallel execution support
- Multiple report formats (summary, detailed, json, junit)
- Built-in assertion functions (`assert`, `assert_eq`, `assert_contains`)
- Performance timing utilities
- Graceful error handling and reporting

#### 2. **Plugin Automation (`setup.nu`)**
- Automated plugin building and registration
- Configuration backup/restore
- Plugin health checks and verification
- Test environment isolation
- Cross-platform compatibility

#### 3. **Test Data (`fixtures/`)**
- Comprehensive test data covering all Nushell types
- Unicode, special characters, edge cases
- Performance testing configurations
- Real-world API keys, tokens, connection strings

#### 4. **Initial Test Suites**
- **Wrap Commands** (`commands/wrap_commands.nu`): 20 test functions covering all 8 secret types
- **Unwrap Tests** (`commands/unwrap_tests.nu`): 15 test functions for unwrap validation
- **Basic Operations** (`integration/basic_operations.nu`): 12 integration test functions

### Test Coverage Achieved

#### Command Coverage
- ✅ Unified wrap command (`secret wrap` with automatic type detection)
- ✅ Unwrap command with all secret types
- ✅ Utility commands (`validate`, `type-of`, `info`)
- ✅ Error handling for invalid inputs
- ✅ Help and documentation verification

#### Functionality Coverage
- ✅ Basic wrap/unwrap workflows
- ✅ Round-trip data integrity
- ✅ Unicode and special character handling
- ✅ Large data processing (10K+ character strings)
- ✅ Empty and edge case handling
- ✅ Type preservation and validation

#### Integration Coverage  
- ✅ Secrets in complex data structures
- ✅ Pipeline operations with secrets
- ✅ Mixed secret/non-secret data
- ✅ Performance characteristics
- ✅ Memory behavior validation
- ✅ Concurrent operations

### Usage

#### Quick Start
```bash
# Run all tests
./scripts/run_nu_tests.sh

# Run specific test suite
./scripts/run_nu_tests.sh --suite commands --verbose

# Setup only (for development)
./scripts/run_nu_tests.sh --setup-only
```

#### Development Testing
```nushell
# From tests/nushell directory
use setup.nu; setup_plugin
use runner.nu; main --suite commands --verbose
```

## 🔄 Next Steps (Phase 6.2)

### Planned Enhancements
1. **Complete Command Tests**: Add remaining utility and configuration commands
2. **Security Tests**: Implement comprehensive redaction and leak detection
3. **Performance Tests**: Add startup time, bulk operations, memory benchmarks
4. **CI Integration**: GitHub Actions workflow for automated testing
5. **Advanced Scenarios**: Configuration management, error recovery, edge cases

### Benefits Achieved

#### Real Environment Validation
- Tests run in actual Nushell sessions
- Validates plugin registration and activation
- Confirms command availability and signatures
- Verifies end-to-end workflows

#### Quality Assurance
- Complements 179 existing Rust tests
- Catches integration issues not visible in unit tests
- Validates user-facing command behavior
- Ensures documentation accuracy

#### Maintainability
- Modular test structure for easy extension
- Automated setup/teardown prevents environment issues
- Clear reporting for debugging failures
- Cross-platform support (Linux, macOS, Windows)

## 📊 Current Status

- **Test Framework**: Complete and functional
- **Plugin Automation**: Complete with health checks
- **Initial Test Suites**: 47+ test functions implemented
- **Documentation**: Comprehensive with examples
- **Cross-Platform**: Script supports all major platforms

**Phase 6.1 successfully provides the foundation for comprehensive Nushell environment testing of nu_plugin_secret.** 🎉
