What are the best practices for testing in Svelte?

When testing in Svelte, it's important to focus on component isolation, use testing libraries like Jest or Testing Library, and ensure you cover both unit and integration tests.

Can you explain how to set up Jest for Svelte testing?

To set up Jest for Svelte, you need to install the necessary packages like 'jest', 'babel-jest', and 'svelte-jester'. Then, configure Jest in your package.json or a separate jest.config.js file to handle Svelte files.

What about testing Svelte stores?

For testing Svelte stores, you can create a test file that imports the store and checks its initial state, updates, and subscriptions using Jest's testing functions.

Are there any specific tools you recommend for Svelte testing?

Yes, I recommend using Svelte Testing Library for component testing, Jest for running tests, and Cypress for end-to-end testing.
