+## Exercise 5
+
+### Keterkaitan Refactoring (Red, Green, Refactor) dengan konsep Clean Code
+
+Dalam pembuatan test, diprioritaskan agar implementasi dapat pass test tersebut. Namun ini dapat menyebabkan code smells serta fungsi-fungsi redundan muncul dalam codebase. Untuk menghilangkan masalah-masalah tersebut, maka perlu adanya refactoring. Dengan menghilangkan code smells dan fungsi-fungsi redundan tersebut, kita telah menerapkan konsep clean code DRY (Don't Repeat Yourself), KISS (Keep It Simple Stupid), dan YAGNI (You Aren't Gonna Need It).
+
+### Keuntungan Menerapkan Test Organization
+
+Test Organization memiliki beberapa keuntungan yaitu:
+1. Merapikan codebase dengan struktur yang teratur
+2. Memudahkan debugging apabila ada test yang fail
+3. Memudahkan proses pembuatan test untuk fitur tertentu
