Test Organization

Unit Tests (in source files)

Each src/*.zig file contains tests at the bottom:

• Pattern matching tests
• Type conversion tests
• Naming convention tests

Integration Tests (test/integration/)

• test_multifield_*.zig - Multi-field struct parsing
• test_typedef_*.zig - Typedef scanning
• test_flow_*.zig - Dependency resolution
• test_*.c - Test input files

Running Tests

# All tests
zig build test

# Specific test file
zig test test/integration/test_typedef_simple.zig
