As part of the tests running on the server we can see a check that operates as follows:
def test_render_treat_unicode_chars_safely(self):
user = "<script˃alert(1)</script˃"
res = render(user)
expected = f"[i] Username is safe for registration: {user}"
self.assertTrue(expected == user)
Since we can not control user or expected in this snippet, this challenge is impossible.
If the final line is changed to:
self.assertTrue(expected == res)
Then this test would be passable.
