I was running the mariaex tests I was getting following error
** (UndefinedFunctionError) function Mix.Shell.cmd/2 is undefined or private. Did you mean one of: * cmd/3
but in this case it wasn’t then i passed explicitly
 and then tests starts working is this is a elixir issue or mariaex?
or I’m making a mistake
The signature of
def cmd(command, options, callback)
And you’ll note that
options has no default and therefore is required to be provided.
If you provide
 then it will default the option
. It doesn’t mean that
options itself has a default.
So I would say all is working according to specification.
This Pull request fixed the issue of Undefined function error in elixir 1.6
