An example of an AI chatbot conversation about using Jest with Vue Test Utils for advanced testing techniques.
How can I use Jest with Vue Test Utils for advanced testing?
You can use Jest with Vue Test Utils to create unit tests for your Vue components. What specific features are you interested in?
I'm particularly interested in mocking components and testing lifecycle hooks.
For mocking components, you can use the stubs option in Vue Test Utils. To test lifecycle hooks, you can use wrapper.vm.$nextTick() to wait for updates.
Can you give me an example of mocking a child component?
Sure! You can mock a child component like this: shallowMount(MyComponent, { stubs: { ChildComponent: true } }). This way, the child won't be rendered.
What about testing emitted events?
You can test emitted events by using wrapper.emitted() to check if the event was emitted and wrapper.vm.$emit('eventName') to trigger it.
