How can I implement test-driven development in my Node.js app?

To implement TDD in your Node.js app, start by writing a test for a small feature before coding it. Use a testing framework like Mocha or Jest.

What are some best practices for writing tests in Node.js?

Some best practices include keeping tests isolated, using descriptive names, and testing both positive and negative cases.

Can you show me an example of a simple test case?

Sure! Here's a simple test case using Jest:

test('adds 1 + 2 to equal 3', () => {
  expect(1 + 2).toBe(3);
});

How do I run my tests after writing them?

You can run your tests by using the command npm test in your terminal, assuming you have set up your package.json correctly.
