What are the best practices for snapshot testing?

Snapshot testing is a great way to ensure your UI components render correctly. Here are some best practices: 1. Keep snapshots small and focused. 2. Update snapshots regularly to reflect changes. 3. Use descriptive names for your snapshots. 4. Review snapshots during code reviews.

How often should I update my snapshots?

You should update your snapshots whenever there are intentional changes to your components or when you refactor code. Regular updates help keep your tests relevant.

What tools can I use for snapshot testing?

Popular tools for snapshot testing include Jest, Enzyme, and React Testing Library. Each has its own features, so choose one that fits your project needs.

Can snapshot testing replace other types of testing?

Snapshot testing is useful, but it shouldn't replace other testing methods like unit tests or integration tests. It's best used in conjunction with them.

What should I do if a snapshot test fails?

If a snapshot test fails, first check if the change was intentional. If so, update the snapshot. If not, investigate the cause of the failure.
