Fix --test mode in Windows (/dev/null)

[tbolon]

When using --test mode on windows, an error is raised:

error: Issue writing to /dev/null: Os { code: 3, kind: NotFound, message: "The system cannot find the path specified." }

On windows, you should use > nul instead

[tbolon]

I think to line to change is in options.rs where you should change the string depending on the current OS.

Thanks, you're right for the fix. We will add the fix in the next release.

For the time-being, you could use the equivalent options
--output nul --progress --summary

The fix is now merged into master.
