# Core Language Tests

This directory contains tests for the fundamental features of the rawk language.

## Test Files

### `test_suite.rawk` - Comprehensive Test Suite
The main test suite that covers all core language features:
- Basic function definitions and calls
- Multi-line functions
- Nested function calls
- Function calls within function bodies
- Edge cases and error conditions
- Boolean assertions
- Array operations
- Conditional expressions
- Complex expressions

**Run with:**
```bash
awk -f ../../rawk.awk test_suite.rawk | awk -f -
```

### `test_basic.rawk` - Basic Functions
Tests basic single-line function definitions and calls:
- Addition, multiplication, string concatenation
- Function call replacement with internal names

**Run with:**
```bash
awk -f ../../rawk.awk test_basic.rawk | awk -f -
```

### `test_multiline.rawk` - Multi-line Functions
Tests multi-line function definitions:
- Complex function bodies with multiple statements
- Return statements
- Array processing within functions

**Run with:**
```bash
awk -f ../../rawk.awk test_multiline.rawk | awk -f -
```

### `test_edge_cases.rawk` - Edge Cases
Tests edge cases and error conditions:
- Functions with no arguments
- Functions with many arguments
- Complex expressions
- String operations
- Conditional expressions
- Array access

**Run with:**
```bash
awk -f ../../rawk.awk test_edge_cases.rawk | awk -f -
```

### `test_recursive.rawk` - Recursive Functions
Tests recursive function support:
- Factorial function
- Fibonacci function
- Countdown function
- Self-referential function calls

**Run with:**
```bash
awk -f ../../rawk.awk test_recursive.rawk | awk -f -
```

### `test_array_fix.rawk` - Array Handling
Tests array operations and utilities:
- Basic array operations
- Standard library array functions
- Associative arrays
- Array statistics

**Run with:**
```bash
awk -f ../../rawk.awk test_array_fix.rawk | awk -f -
```

### `test_failure.rawk` - Assertion Failures
Demonstrates the assertion system:
- Shows how failing tests are reported
- Tests error message formatting
- Validates test framework functionality

**Run with:**
```bash
awk -f ../../rawk.awk test_failure.rawk | awk -f - 2>&1
```

## Expected Results

All tests should pass with clear output showing:
