Hi @yamt, could you make a change in test so it's expected to fail? Tests are based on exit codes, IIRC WAMR didn't by default pass exit code from module to user through iwasm. Is there any build flag to enable this behavior? If so, probably worth adding a comment in the adapter.

iirc, wamr doesn't have a way to preserve wasi exit code.
probaby i will add it in upstream.

in the meantime i added a comment.
