Vue Test Utils Patterns FAQs

Question 1

When should I use flushPromises in my Vue tests?

Accepted Answer

Use flushPromises() whenever you have asynchronous operations that Vue's reactivity system doesn't track, such as external API calls or timers, to ensure all promises resolve before assertions.

Question 2

Can I test Vue 3 composables with this skill?

Accepted Answer

Yes, the skill includes specific patterns for testing standalone composables both in isolation and within the context of a component.

Question 3

Why does this skill recommend mount over shallowMount?

Accepted Answer

mount() performs full rendering of child components and slots, making the test environment more closely resemble production and providing higher confidence in component integration.

Question 4

How do I handle Pinia stores using this skill?

Accepted Answer

The skill utilizes createTestingPinia(), which automatically mocks your stores and allows you to easily inspect actions and state without manual boilerplate.

Question 5

Why are data-test attributes preferred for selectors?

Accepted Answer

CSS classes and IDs are prone to change during styling refactors; data-test attributes provide a stable, dedicated contract for testing that decouples logic from presentation.
