How do I test Vue composables effectively?

How do I test Vue composables effectively?

To test Vue composables, you can use testing libraries like Jest or Vue Test Utils. Start by isolating the composable and writing unit tests for its functionality.

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

Sure! If you have a composable that manages a counter, you could write a test to check if the increment function increases the counter value as expected.

What about testing side effects in composables?

For side effects, you can use mocks to simulate external dependencies and verify that the composable behaves correctly when those dependencies change.

Are there any best practices for testing composables?

Yes, keep your composables small and focused, write clear and descriptive tests, and ensure you cover edge cases.
