An example of an AI chatbot conversation about advanced testing with Vue Test Utils.
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' } }). Then, you can assert the rendered output.
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 handle asynchronous operations in my tests?
You can use await with nextTick() to wait for the DOM updates after an asynchronous operation. This ensures your assertions are made after the updates.
