This following is as expected for <path>/lua all.lua? tests not performed:
testC not active: skipping API tests <<< testC not active: skipping opcode tests <<< testC not active: skipping API tests <<< testC not active: skipping yield/hook tests <<< testC not active: skipping coroutine API tests <<<
Did you rebuild Lua with ltests on as explained in http://www.lua.org/tests/5.2/#internal ?
