Python Python Testing Be Assertive assertIn

Bummer: Didn't find a test for `get_anagrams()` using `self.assertIn()`

I am testing assertIn within the test_in_anagrams method. I am getting an error. It does not reconizing that I am testing get_anagrams() with self.assertIn(). The test passes when I test it elsewhere. word is a string. words is a list of strings.

import unittest

from string_fun import get_anagrams

class AnagramTests(unittest.TestCase):

    def test_in_anagrams(self):
        word = 'house'
        words = get_anagrams('treehouse')
        self.assertIn(word, words)
import itertools

def is_palindrome(yarn):
    """Return whether or not a string is a palindrome.

    A palindrome is a word/phrase that's the same in
    both directions.
    return yarn == yarn[::-1]

def get_anagrams(*yarn):
    """Return a list of anagrams for a string."""
    # If only one letter came in, return it
    if yarn:
        if len(yarn[0]) <= 1:
            return list(yarn)
        raise ValueError("Must provide at least two letters")

    # Get all of the words from the dictionary
    words = set([
        w.strip().lower() for w in open('words.txt')

    output = set()
    for thread in yarn:
        thread = thread.lower()
        # Find all possible anagrams
        for i in range(2, len(thread)):
            fibers = set(
                [''.join(w) for w in itertools.permutations(thread, i)]

    # Finally, return all of the combinations that are in the dictionary
    return sorted(list(output))

Your code makes sense, but the challenge must want you to pass get_anagrams() to self.assertIn. When I did that, it passed:

self.assertIn('house', get_anagrams('treehouse'))
