"I am" is two words, not one. I hope you wouldn't write "Youare"
or "Heis" :-) Whenever you write "Iam", I read it as the name "Ian", which
is very distracting.

But the test *hasn't* failed. A skipped test is not a failed test.

If you want the test to count as failed, you must let it fail. You can use
the fail() method for that.

Raising a SkipTest exception is equivalent to calling the skipTest method,
which marks the test as an expected skipped test, not a failure. Since it
is not a failure, it doesn't display the exception.

If you run unittest in verbose mode, the skip message will be displayed. See
the documentation here:
