Test media always fail

Test media always fail but when I install it without test media it installs normaly, what is the problem? also when using root account it doesn’t require password as other linux distribution, is root secured in some other way?

It is most likely because you are writing the ISO to your USB stick in Windows. And again most probably by Rufus. Pay attention to this paragraph in Installation Guide:

Note: Using Rufus to create the installation medium means that you won't be able to choose the 
"Test this media and install Qubes OS" option mentioned in the example below. Instead, choose 
the "Install Qubes OS" option.
