What is a primary objective of Test$-$Driven Development $($TDD$)$ in the software development process?

TDD focuses on enhancing the software's graphical user interface to make it more user$-$friendly.

Writing tests before the actual code ensures that the code is being written to pass predefined conditions.

TDD$\text{'}$s main goal is to document the software's functionality for end$-$users.

TDD aims to reduce the cost of software licensing and distribution.
