What are some tips for using Vue Test Utils effectively?

Here are some tips for using Vue Test Utils effectively: 1. Use shallowMount for unit tests to isolate components. 2. Leverage the setData method to simulate state changes. 3. Use wrapper.vm to access component methods and properties directly.

Can you explain how to use shallowMount?

Sure! shallowMount is a method that creates a shallow wrapper for your component. It renders the component but does not render its child components, which helps in isolating the component for unit testing.

What about testing events in Vue Test Utils?

To test events, you can use the trigger method on the wrapper. For example, wrapper.find('button').trigger('click') simulates a click event on a button.

How can I mock child components?

You can mock child components by using the stubs option in mount or shallowMount. For example, shallowMount(MyComponent, { stubs: { ChildComponent: true } }) will replace ChildComponent with a stub.
