I know about running test this way:
$ ./python -m test -v test_xmlrpc

And it works.

I am just wondering whether I should be able to run test this way: ./python Lib/test/test_blabla.py?

Because running other tests without test module works, for example: ./python Lib/test/test_ast.py. Only test which imports random module fails.
