Unit Tests

Back to Testing Contracts

Unit tests cover individual compiler components in isolation. They live in tests/ and inline #[cfg(test)] modules.

# Run all unit tests
cargo test --workspace

# Run tests for a specific module
cargo test lexer_tests
cargo test parser_tests
cargo test semantic_tests
cargo test runtime_tests

# Run with output visible (useful for debugging)
cargo test -- --nocapture

# Run a specific test by name
cargo test test_compile_simple_storage

# Run tests in parallel (default) or single-threaded
cargo test -- --test-threads=1

Runtime Tests

The embedded NeoVM runtime has extensive unit tests covering opcodes, syscalls, storage, iterators, and gas accounting:

# All runtime tests
cargo test runtime_

# Specific runtime areas
cargo test runtime_captures_return_payload
cargo test runtime_handles_empty_script
