How do I test Pinia stores in my Vue.js application?

To test Pinia stores, you can use libraries like Jest or Vue Test Utils. Start by creating a test file for your store.

Can you give me an example of a test case for a Pinia store?

Sure! Here's a simple test case:

import { createPinia, setActivePinia } from 'pinia';
import { useMyStore } from '@/stores/myStore';

setActivePinia(createPinia());

test('increments count', () => {
  const store = useMyStore();
  store.increment();
  expect(store.count).toBe(1);
});

What about testing actions and getters?

You can test actions by calling them and checking the state afterward. For getters, simply access them after performing actions to verify their output.

Are there any best practices for testing Pinia stores?

Yes! Keep your tests isolated, use mock data, and ensure you cover edge cases to make your tests robust.
