# rawk Test Suite

This directory contains the comprehensive test suite for the rawk language, organized by category.

## Directory Structure

### `core/` - Core Language Features
Tests for fundamental language features like function definitions, calls, recursion, and edge cases.

### `real_world/` - Real-World Examples
Practical examples that demonstrate rawk's utility for common data processing tasks.

### `stdlib/` - Standard Library Tests
Tests for the built-in standard library functions.

### `data/` - Test Data Files
Sample data files used by the real-world examples.

## Running Tests

### Run All Core Tests
```bash
# Run the comprehensive test suite
awk -f ../rawk.awk core/test_suite.rawk | awk -f -

# Run individual core tests
awk -f ../rawk.awk core/test_basic.rawk | awk -f -
awk -f ../rawk.awk core/test_multiline.rawk | awk -f -
awk -f ../rawk.awk core/test_recursive.rawk | awk -f -
```

### Run Real-World Examples
```bash
# System monitoring
awk -f ../rawk.awk real_world/test_system_monitor.rawk | awk -f - data/test_data.txt

# Log parsing
awk -f ../rawk.awk real_world/test_log_parser.rawk | awk -f - data/test_logs.txt

# CSV processing
awk -f ../rawk.awk real_world/test_csv_processor.rawk | awk -f - data/test_employees.csv
```

### Run Standard Library Tests
```bash
awk -f ../rawk.awk stdlib/test_stdlib_simple.rawk | awk -f -
```
