How do I implement async testing in my application?

To implement async testing, you can use testing frameworks like Jest or Mocha that support async functions. Would you like a code example?

Yes, please provide a code example using Jest.

Sure! Here's a simple example:

test('async test example', async () => {
  const data = await fetchData();
  expect(data).toBe('expected value');
});

This tests an async function called fetchData. Do you need help with anything else?

What if I want to test multiple async functions?

You can use Promise.all to test multiple async functions concurrently. Here's an example:

test('multiple async tests', async () => {
  const results = await Promise.all([fetchData1(), fetchData2()]);
  expect(results[0]).toBe('value1');
  expect(results[1]).toBe('value2');
});
