How can I get started with testing in Node.js?

To get started with testing in Node.js, you can use frameworks like Mocha, Jest, or Jasmine. Do you have a specific framework in mind?

I've heard a lot about Jest. What are its advantages?

Jest is great for its simplicity and built-in features like mocking and code coverage. It's also very fast and has a large community.

Can you show me a simple example of a Jest test?

Sure! Here's a basic example:

const sum = (a, b) => a + b;

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

What other testing tools should I consider?

You might also want to look into Mocha for flexible testing, Chai for assertions, and Supertest for API testing.
