# Variables

## Overview
Variables in test suites provide a flexible way to manage and reuse data across test cases. This feature allows for dynamic test execution and data-driven testing.

## Variable Types

### Global Variables
- **System Variables**: Pre-defined system variables
- **Environment Variables**: Environment-specific variables
- **Suite Variables**: Variables shared across suite
- **Project Variables**: Project-level variables
- **Custom Variables**: User-defined variables

### Data Types
- **String**: Text values
- **Number**: Numeric values
- **Boolean**: True/False values
- **Array**: List of values
- **Object**: Complex data structures
- **Date/Time**: Temporal values

### Scope Levels
- **Global Scope**: Available everywhere
- **Suite Scope**: Available in suite
- **Test Case Scope**: Available in test case
- **Step Scope**: Available in step
- **Local Scope**: Available in specific context

## Usage

### Creating Variables
1. Navigate to Variables section
2. Click "Add Variable"
3. Define variable properties
4. Set initial value
5. Save variable

### Managing Variables
- **View Variables**: List all variables
- **Edit Variables**: Modify variable properties
- **Delete Variables**: Remove variables
- **Import/Export**: Transfer variable definitions
- **Search/Filter**: Find specific variables

### Variable Operations
- **Assignment**: Set variable values
- **Concatenation**: Combine variables
- **Type Conversion**: Change data types
- **Validation**: Verify variable values
- **Encryption**: Secure sensitive data

## Best Practices
- Use meaningful variable names
- Document variable purpose
- Maintain variable scope
- Regular cleanup of unused variables
- Version control variable definitions
- Secure sensitive variable data
- Monitor variable usage
- Regular variable review
- Backup variable configurations
- Document variable dependencies
