In Jest it easy to write clear and expressive test assertions. It support snapshot testing which makes it easy to identify unintended changes easily. It provides built-in tools for mocking functions which is very useful in testing. Review collected by and hosted on G2.com.

I have not faced any issues while using it but its auto mocking feature can be improved. Other than that it is best testing framework I have used. Review collected by and hosted on G2.com.
