What are some effective strategies for testing Vue composables?

When testing Vue composables, consider using unit tests with Jest or Vue Test Utils. Focus on testing the logic and side effects.

Can you give me an example of a unit test for a composable?

Sure! Here's a simple example using Jest:

import { useCounter } from './useCounter';

test('should increment counter', () => {
  const { count, increment } = useCounter();
  increment();
  expect(count.value).toBe(1);
});

What about testing side effects in composables?

For side effects, you can use mocks to simulate external dependencies. Ensure to test how your composable interacts with them.

Are there any best practices for organizing tests?

Yes! Keep your tests organized by grouping them by functionality, and use descriptive names for your test cases to improve readability.
