How can I use Vue Test Utils for advanced testing scenarios?
Vue Test Utils provides a powerful API for testing Vue components. You can simulate user interactions, test lifecycle hooks, and even mock dependencies.
Can you give me an example of testing a component with props?
Sure! You can mount a component with props like this: mount(MyComponent, { props: { myProp: 'value' } })
. This allows you to test how the component behaves with different prop values.
What about testing emitted events?
To test emitted events, you can use the emitted()
method after simulating the event. For example, wrapper.vm.$emit('myEvent')
and then check with expect(wrapper.emitted().myEvent).toBeTruthy();
.
How do I test asynchronous components?
For asynchronous components, you can use await wrapper.vm.$nextTick()
to wait for the next DOM update after an async operation.
