Run the complete suite with:
python -m unittest discover -s tests -v
Or use:
make test
The integration test assembles and links the ROM, then validates its header,
mapper, banks, vectors, CHR data, and final size. It is skipped with an
explicit message when ca65 or ld65 is unavailable.
To include the optional headless Mesen behavior test, point MESEN_PATH to
the emulator executable before running the suite. The test compiles the
behavior examples, executes their ROMs, and verifies final variables,
procedure-parameter storage when applicable, and the universal background
color:
$env:MESEN_PATH = "C:\path\to\Mesen.exe"
python -m unittest discover -s tests -v
The behavior test is skipped clearly when Mesen or the cc65 toolchain is unavailable.
