What is Test-Driven Development in C++?

What is Test-Driven Development in C++?

Test-Driven Development (TDD) is a software development process where you write tests before writing the actual code. In C++, this means you first create unit tests for your functions, and then implement the functions to pass those tests.

How do I start with TDD in a C++ project?

To start with TDD in C++, you can follow these steps: 1. Choose a testing framework like Google Test. 2. Write a test for a small piece of functionality. 3. Run the test and see it fail. 4. Write the minimum code necessary to pass the test. 5. Refactor the code while keeping the tests green.

What are the benefits of using TDD?

The benefits of TDD include improved code quality, easier debugging, and better design. It encourages you to think about the requirements and design before coding, leading to more maintainable and reliable software.

Can you give me an example of a simple TDD cycle in C++?

Sure! Let's say you want to create a function that adds two numbers. First, you write a test that checks if add(2, 3) returns 5. Then, you implement the add function to pass this test. After that, you can refactor the code if needed, ensuring the test still passes.
