+## Exercise 6 - Mutation Testing
+
+Pada kesempatan kali ini, saya membuat 2 mutant pada *views.py* di fungsi todo_list_comment
+Mutasi 1:
+```python
+def todo_list_comment(items):
+    if (items.count() != 0):
+        return 'yey, waktunya berlibur'
+    elif (1 <= items.count() <= 4):
+        return 'sibuk tapi santai'
+    elif (items.count() >= 5):
+        return 'oh tidak'
+```
+Mutation 2:
+```python
+def todo_list_comment(items):
+    if (items.count() == 0):
+        return 'yey, waktunya berlibur'
+    elif (1 <= items.count() <= 5):
+        return 'sibuk tapi santai'
+    elif (items.count() >= 5):
+        return 'oh tidak'
+```
+Lalu untuk salah satu contoh yang saya gunakan adalah untuk mutasi ke-2. Di mana test yang strongly
+kill mutasi 2 adalah test_comment_5_or_more_items.
+
+Test case tersebut strongly kill mutant karena saat jumlah item 5, program masuk ke kondisional kedua sehingga expected output salah.
+
+*Additional*
+
+Saya juga telah mencoba untuk menggunakan salah satu *tools* untuk automasi mutant test. Saya menggunakan
+MutPy. Dengan command berikut:
+```
+python3 manage.py muttest lists --modules lists.views
+```
+Saya mendapatkan bahwa terdapat mutasi yang dibuat secara otomatis dan semuanya sudah terbunuh secara kuat.
