How do I use Jest for mocking in Vue components?

You can use Jest's mocking functions to create mock implementations of your Vue components. This allows you to isolate the component you're testing.

Can you show me an example of mocking a method in a Vue component?

Sure! You can use jest.fn() to create a mock function. For example, if you have a method called fetchData, you can mock it like this: const fetchDataMock = jest.fn();.

What about mocking props in a Vue component?

You can pass mocked props to your component when mounting it in your test. For example: mount(MyComponent, { props: { myProp: 'mockedValue' } });.

Are there any best practices for mocking in Jest?

Yes, keep your mocks simple and only mock what you need for the test. Avoid over-mocking, as it can lead to tests that are hard to maintain.
