* tests: automated headless FreeDOS QEMU smoke Fully-automated counterpart to the manual run_freedos_qemu.sh: overlays the FreeDOS image (no mutation), stages the interpreter and a SYSTEM-terminated smoke on C:, injects the run plus poweroff into the image's startup batch, boots headless, and diffs OUT.TXT against the golden file. Local-dev only (needs qemu, a FreeDOS qcow2, mtools, nbd, and passwordless sudo); CI keeps using the DOSBox-X path. Exercises the binary on a real FreeDOS install rather than DOSBox-X emulation. * Release 0.18.0 Cross-language linking (link BASIC into C/Fortran, call C from BASIC via '$EXTERN), the v0.18 codegen/perf batch (paren string-comparison fix, --no-gc-check/--fast-math, larger 32-bit caps, process-local DATE$/TIME$), and the automated FreeDOS QEMU smoke. Bumps GW_VERSION and updates the banners, CHANGES.TXT, and the development history table. --------- Co-authored-by: Eremey Valetov <evvaletov@users.noreply.github.com>

Tests
72 automated test programs in tests/programs/, plus 4 classic interactive
programs in tests/classic/ (Hamurabi, Lunar Lander, Gunner, Diamond from
David Ahl's BASIC Computer Games). 14 Jupyter kernel tests. 63 compiler
tests (eligible programs compiled to native executables via
gwbasic-compile; run bash tests/run_compiler_tests.sh).
Run the full automated suite:
bash tests/run_tests.sh # interpreter (72 tests)
python -m gwbasickernel.test_kernel # Jupyter kernel (14 tests)
Each interpreter test has a 5-second timeout. 68 tests have .expected golden
files for output regression detection. Tests without golden comparison:
datetime, on_timer, timer_stop (timing-dependent), color_test (visual).
Compatibility Testing
Compare output against real GWBASIC.EXE running under DOSBox-X:
# Generate .expected files from GWBASIC.EXE (requires DOSBox-X Flatpak)
bash tests/run_compat.sh --generate
# Compare gwbasic output against .expected
bash tests/run_compat.sh
CI
GitHub Actions runs on every push to main and on pull requests. The workflow
builds the project with PulseAudio support and runs all 72 test programs.
