How can I use Vue Test Utils for advanced testing scenarios?
You can use Vue Test Utils to test Vue components by simulating user interactions, mocking dependencies, and asserting component behavior.
Can you give me an example of mocking a component?
Sure! You can use jest.mock()
to mock a child component in your test. For example: jest.mock('@/components/ChildComponent.vue')
.
What about testing asynchronous components?
For asynchronous components, you can use await wrapper.vm.$nextTick()
to wait for the DOM updates after state changes.
How do I test emitted events from a component?
You can use wrapper.emitted()
to check if an event was emitted and wrapper.vm.$emit('eventName')
to trigger it in your tests.
