Can you explain advanced examples of async/await in Jasmine?

Sure! Advanced examples of async/await in Jasmine involve testing asynchronous code more effectively. For instance, you can use async functions in your specs to handle promises.

Can you provide a specific code example?

Absolutely! Here's an example:

it('should fetch data asynchronously', async () => {
  const data = await fetchData();
  expect(data).toEqual(expectedData);
});

This test waits for fetchData() to resolve before making assertions.

What if the promise is rejected?

In that case, you can use try...catch to handle the error. Here's how:

it('should handle errors', async () => {
  try {
    await fetchData();
  } catch (error) {
    expect(error).toEqual(expectedError);
  }
});

Are there any best practices for using async/await in Jasmine?

Yes! Always ensure your tests are clear and concise. Use async functions for better readability, and handle errors gracefully to avoid unhandled promise rejections.
