Testing

For detailed guidance on writing new tests (lit test structure, FileCheck patterns, test output locations), see test/TESTING.md.

Compiler tests

Full compiler suite: ninja -C build check-ttlang-all (MLIR, bindings, end-to-end, pytest, Python lit).
Quick check (MLIR + bindings only): ninja -C build check-ttlang.
Single MLIR file: llvm-lit test/ttlang/<path>.mlir.

Simulator tests

python -m pytest test/sim — not included in check-ttlang-all, must be run separately.

Python tests

Python API: python -m pytest test/python.

Build hygiene

Format and lint before review: pre-commit run --all-files.
Reconfigure if dependencies change: rerun cmake -G Ninja -B build after pulling toolchain updates.
