# CLI Acceptance Testing Specification
**Version**: 1.0  
**Date**: 2025-09-10  
**Status**: Implementation Required  
**Coverage Target**: 100% of CLI commands, subcommands, and flags

## 1. Overview

This specification defines comprehensive acceptance testing for the `pmat` CLI tool, ensuring 100% coverage of all commands, subcommands, flags, and edge cases. Every CLI interface must be tested for correctness, error handling, and user experience.

## 2. Testing Methodology

### 2.1 Testing Approach
- **Black Box Testing**: Test CLI interface without knowledge of internal implementation
- **Integration Testing**: Test complete workflows from command input to output
- **Error Path Testing**: Verify all error conditions and user-friendly messages
- **Performance Testing**: Ensure reasonable response times for all operations
- **Cross-Platform Testing**: Verify behavior across different operating systems

## 4. Test Case Specifications

### 4.1 Test Case Template
Each test case must include:
```rust
#[test]
fn test_command_scenario() {
    // Arrange
    let test_setup = setup_test_environment();
    let expected_outcome = define_expected_result();
    
    // Act
    let result = run_cli_command(&["pmat", "command", "--flag", "value"]);
    
    // Assert
    assert_command_success(&result);
    assert_output_format(&result.stdout, OutputFormat::Expected);
    assert_error_handling(&result.stderr);
    assert_exit_code(&result, 0);
    assert_performance(&result.execution_time, Duration::from_secs(30));
    
    // Cleanup
    cleanup_test_environment(test_setup);
}
```

### 4.2 Critical Test Scenarios

#### 4.2.1 Happy Path Testing
- **Valid Input**: All commands with correct parameters
- **Default Values**: Commands without optional parameters  
- **Minimal Input**: Commands with minimum required parameters
- **Maximum Input**: Commands with all possible parameters

#### 4.2.2 Error Path Testing
- **Invalid Commands**: Non-existent commands and subcommands
- **Invalid Flags**: Unknown flags and malformed flag syntax
- **Invalid Values**: Wrong data types, out-of-range values
- **Missing Files**: File paths that don't exist
- **Permission Errors**: Files without read/write permissions
- **Network Errors**: Server commands when network unavailable

#### 4.2.3 Edge Case Testing
- **Empty Projects**: Running analysis on empty directories
- **Large Projects**: Performance with massive codebases
- **Unicode Handling**: File paths and content with Unicode characters
- **Long Paths**: Very long file paths and deep directory structures
- **Special Characters**: File names with special characters

#### 4.2.4 Integration Testing
- **Pipeline Testing**: Chaining multiple commands together
- **File Generation**: Commands that create files followed by analysis
- **Configuration**: Commands interacting with config files
- **Cache Behavior**: Commands with caching enabled/disabled

## 5. Output Validation

### 5.1 Output Format Validation
Each command output must be validated for:
- **JSON Format**: Valid JSON when `--format json` used
- **Human Format**: Readable text output for human consumption
- **CSV Format**: Valid CSV with proper headers and escaping
- **Markdown Format**: Valid markdown syntax
- **SARIF Format**: Valid SARIF schema compliance

### 5.2 Content Validation
- **Data Accuracy**: Verify calculated metrics are correct
- **Completeness**: All expected fields are present
- **Consistency**: Same input produces same output
- **Localization**: Error messages are user-friendly

## 6. Performance Requirements

### 6.1 Response Time Targets
| Command Category | Max Response Time | Notes |
|-----------------|-------------------|--------|
| Help/Version | 1 second | Near-instant feedback |
| Simple Analysis | 30 seconds | Basic file analysis |
| Complex Analysis | 5 minutes | Deep analysis with ML |
| Code Generation | 2 minutes | Template generation |
| Server Commands | 10 seconds | Service startup |

### 6.2 Resource Usage Limits
- **Memory Usage**: Max 8GB for any single operation
- **CPU Usage**: Should not consume 100% CPU for >5 minutes  
- **Disk Usage**: Temporary files should be cleaned up
- **Network Usage**: Reasonable timeout and retry behavior

## 7. Error Handling Requirements

### 7.1 Error Message Quality
All error messages must:
- **Be User-Friendly**: No technical jargon or stack traces
- **Be Actionable**: Include suggestions for resolution
- **Be Consistent**: Follow same format across all commands
- **Include Context**: Show what command/input caused the error

### 7.2 Exit Code Standards
| Exit Code | Meaning | Usage |
|-----------|---------|--------|
| 0 | Success | Command completed successfully |
| 1 | General Error | Invalid usage, file not found, etc. |
| 2 | Analysis Failure | Analysis completed but found issues |
| 3 | Configuration Error | Config file invalid or missing |
| 4 | Network Error | Server/network connectivity issues |
