When should I use mount() vs shallowMount()?

Use mount() by default for realistic integration testing that includes child components. Use shallowMount() only for performance-heavy components or when strict isolation is required.

Why should I use data-test attributes for selectors?

Unlike CSS classes or IDs, data-test attributes act as a stable testing contract that does not break when styling changes or internal logic is refactored.

How does this skill handle asynchronous Vue updates?

It provides patterns for using flushPromises() and mandates awaiting DOM-updating methods like setValue() and trigger() to prevent flaky tests.

Does this support Pinia store testing?

Yes, it includes specific patterns for mocking Pinia stores using createTestingPinia, allowing you to easily simulate state and verify store actions.

Implements professional Vue 3 component testing patterns using Vue Test Utils, covering DOM interactions, Pinia mocking, and asynchronous state updates.

This skill provides a comprehensive framework for testing Vue 3 components with the Composition API. It guides developers through the nuances of full vs. shallow mounting, ensures reliable DOM assertions using data-test attributes, and provides robust patterns for handling asynchronous operations like API calls and store state changes. By standardizing practices around event triggering, prop validation, and store mocking, it helps maintain high test fidelity in complex frontend applications using Pinia and Vue Router.
