How do I handle timeouts in Jest with async/await?

How do I handle timeouts in Jest with async/await?

You can use Jest's built-in timeout feature by setting the timeout in your test using jest.setTimeout(). This allows you to specify how long Jest should wait before failing the test.

Can you show me an example of that?

Sure! Here's a simple example:

jest.setTimeout(10000); // Set timeout to 10 seconds

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

What if my async function takes longer than the timeout?

If your async function takes longer than the specified timeout, Jest will automatically fail the test and report a timeout error. You can adjust the timeout duration as needed.

Is there a way to set a timeout for individual tests?

Yes, you can set a timeout for individual tests by passing a second argument to the test function, like this:

test('my test', async () => { /* test code */ }, 5000); // 5 seconds timeout
