# API Testing

## Overview
API Testing provides comprehensive tools for testing API endpoints, validating responses, and ensuring API functionality. This feature enables thorough testing of APIs with various test scenarios and validations.

## Features

### Test Types
- **Functional Testing**: Basic API functionality
- **Performance Testing**: Load and stress testing
- **Security Testing**: Security validation
- **Integration Testing**: End-to-end testing
- **Regression Testing**: Change validation
- **Negative Testing**: Error handling
- **Data Validation**: Response validation
- **Schema Validation**: Structure validation

### Test Components
- **Request Builder**: Create test requests
- **Response Validator**: Validate responses
- **Test Cases**: Define test scenarios
- **Test Suites**: Organize test cases
- **Test Data**: Manage test data
- **Environment**: Configure test environments
- **Variables**: Handle test variables
- **Assertions**: Define test assertions

### Execution Features
- **Single Test**: Run individual tests
- **Test Suite**: Execute test suites
- **Scheduled Tests**: Schedule test runs
- **Parallel Execution**: Run tests concurrently
- **Continuous Testing**: CI/CD integration
- **Test Reports**: Generate test reports
- **Test Logs**: View execution logs
- **Test History**: Track test results

## Usage

### Creating Tests
1. Select API endpoint
2. Define test scenario
3. Configure test data
4. Set up assertions
5. Save test case

### Running Tests
1. Select test(s) to run
2. Choose environment
