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 create unit tests using frameworks like Google Test or Catch2, ensuring your code meets the requirements from the start.

How do I get started with TDD in C++?

To get started with TDD in C++, first choose a testing framework like Google Test. Then, write a test for a small piece of functionality, run the test (it should fail), implement the code to pass the test, and finally refactor the code while ensuring the test still passes.

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, write a test that checks if the function returns the correct sum. Then, implement the function to pass the test, and finally, refactor if necessary while keeping the test green.
