What are the best snapshot testing tools available?
There are several popular snapshot testing tools, including Jest, Enzyme, and Mocha. Each has its own strengths.
Can you explain how Jest's snapshot testing works?
Jest captures the rendered output of a component and saves it as a snapshot. On subsequent tests, it compares the output to the saved snapshot.
What are the advantages of using snapshot testing?
Snapshot testing helps catch UI changes, ensures consistency, and simplifies testing by reducing the need for manual assertions.
Are there any downsides to snapshot testing?
Yes, over-reliance on snapshots can lead to false positives if not reviewed carefully, and they may not catch all edge cases.
