Asm.js is 100% compatible with normal JavaScript - the only difference is
that it is slower. But for testing this shouldn't be a problem and you can
use any JavaScript interpreter. Google V8's source code has a command-line
version (which Emscripten uses or used at some point for tests too) that
you can build (it is very easy, i did it at the past when i was messing
with Emscripten). Here is some information:

You will obviously need some sort of "interface" between the asm.js
function and the outside world for tests (f.e. what "writeln" would do?)
but you'd need that interface anyway since even for real asm.js use people
will need to provide such interfaces
