# Plugin Integration Test Suite

Comprehensive test suite for the Provisioning platform's plugin system, covering authentication, KMS, and orchestrator plugins with graceful fallback testing.

## Overview

This test suite validates:
- **Plugin Availability**: Detection of installed Nushell plugins
- **Fallback Behavior**: Graceful degradation to HTTP/SOPS when plugins unavailable
- **Complete Workflows**: End-to-end authentication, encryption, and orchestration
- **Performance**: Benchmarking plugin vs HTTP performance
- **Error Handling**: Network failures, invalid data, concurrent access
- **Cross-Plugin Integration**: Multi-plugin workflows

## Test Philosophy

### Graceful Degradation

**All tests pass regardless of plugin availability:**
- ✅ Plugins installed → Use plugins, test performance
- ✅ Plugins missing → Use HTTP/SOPS fallback, warn user
- ✅ Services unavailable → Skip service-dependent tests, report status

### No Hard Dependencies

Tests never fail due to:
- Missing plugins (fallback tested)
- Services not running (gracefully reported)
- Network issues (error handling tested)

### Performance Awareness

Tests measure and report performance:
- **Plugin mode**: <50ms (excellent)
- **HTTP fallback**: <200ms (good)
- **SOPS fallback**: <500ms (acceptable)

## Expected Output

### Successful Run (All Plugins Available)

  }
}
```

## Troubleshooting

### Tests Fail to Run

**Problem**: `nu: command not found`
**Solution**: Install Nushell 0.107.1+
```bash
brew install nushell  # macOS
cargo install nu      # Any platform
```

### Plugin Tests Show Warnings

**Problem**: All plugin tests show "not available"
**Solution**: This is expected behavior if plugins not installed. Tests will use HTTP fallback.

### Service Connection Errors

**Problem**: "Orchestrator not available" warnings
**Solution**: Start orchestrator service:
```bash
cd provisioning/platform/orchestrator
cargo run --release
```

### KMS Backend Errors

**Problem**: "No KMS backends available"
**Solution**: Configure at least one backend in `provisioning/config/plugin-config.toml`

## Development

### Adding New Tests

1. Create test in appropriate file (`*_test.nu`)
2. Follow naming convention: `test_<feature>_<aspect>`
3. Use `std assert` for assertions
4. Handle both plugin and fallback modes
5. Add to integration test workflow if needed

### Example Test Template

```nushell
export def test_new_feature [] {
    print "  Testing new feature..."

    use plugin_module.nu *

    # Test logic
    let result = (do {
        plugin-function args
    } | complete)

    # Assertions
    if $result.exit_code == 0 {
        print "    ✅ Feature working"
    } else {
        print "    ⚠️  Feature not available"
    }
}
```
