I looked this up before, and just did it again.
I found no evidence, neither in the pickaxe nor in file.c,
that Ruby supports this.

There are no filetest 'operators' in Ruby, but you can use 
Kernel#test with a parameter formed by the '?' syntax, e.g. ?A.

test(?A, "somefile.ext")

Ruby is missing perl's -B, -t, and -T equivalents, but it has 
the other ones (?s and ?M are not exactly the same, though).
