How do I handle errors in Vue.js tests using Jest?

You can handle errors in Vue.js tests by using Jest's built-in error handling features. For example, you can use try-catch blocks in your test cases to catch errors and assert them.

Can you give me an example of a test that handles an error?

Sure! Here's a simple example:

it('handles error correctly', async () => {
  try {
    await someAsyncFunction();
  } catch (error) {
    expect(error).toBeInstanceOf(Error);
  }
});

What if I want to test a component that throws an error?

You can use Jest's jest.spyOn to mock the component's method and throw an error. Then, you can assert that the error is handled properly in your test.

Is there a way to test error boundaries in Vue components?

Yes, you can test error boundaries by simulating an error in a child component and checking if the error boundary catches it and displays the fallback UI.
