Have you conducted software quality assurance in your practice?

Yes, in Node.js development practice, quality assurance is an important stage. It usually includes:

• Writing unit tests using frameworks like Mocha, Jest, or Jasmine.
• Using static code analysis (e.g., ESLint) to identify potential errors and enforce style.
• Conducting integration and e2e tests to verify component interactions.
• Setting up CI/CD for automatic test runs on commits.

For example, a simple test with Jest might look like this:

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

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

This practice helps detect bugs early and maintain application stability.
