I hope that's not really what your code says, because the file name you
are passing contains a "tab" character.  You need one of these instead:
    o.Open( "V:/tests/mytest" )
    o.Open( r"V:\tests\mytest" )
    o.Open( "V:\\tests\\mytest" )

No.  The more likely answer is that the Run command failed because the
file name was invalid, so o.Test is not returning a real object.
