# ========== theory ==========
# 
# Mock and MagicMock are all classes in `unitest.mock` library.
#
# ---------- The MagicMock Class ----------
# A MagicMock instance can:
#   * capture the arguments that the method is called with
#   * count how many times it's called
#   * return values that we specify
#   * return the same or different values each time the mocked method is called
