An example of an AI chatbot conversation about TDD in Node.js.
What is Test-Driven Development in Node.js?
Test-Driven Development (TDD) in Node.js is a software development process where tests are written before the actual code. It helps ensure that the code meets its requirements and reduces bugs.
How do I start implementing TDD in my Node.js project?
To start TDD in your Node.js project, first, set up a testing framework like Mocha or Jest. Then, write a test for a small piece of functionality before implementing the code.
Can you give me an example of a simple TDD cycle?
Sure! First, write a test for a function that adds two numbers. Then, run the test (it should fail). Next, implement the function to make the test pass, and finally, refactor the code if necessary.
What are the benefits of using TDD?
Benefits of TDD include improved code quality, easier debugging, and better design decisions, as it encourages you to think about the requirements upfront.
