Have you had experience working with automated tests or software testing?

Yes, I have experience working with automated tests in Node.js. I usually use frameworks such as Jest or Mocha to write unit tests and integration tests. Automated tests help verify the correctness of functions and modules, as well as prevent regressions when making changes.

Example of a simple test with Jest:

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

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

I am also familiar with using mocks and stubs to isolate tested components.
