When configuring Jest, it's important to keep your configuration simple and maintainable. Start with a basic setup and only add configurations as needed.
Should I use a separate configuration file for different environments?
Yes, using separate configuration files for different environments can help manage settings specific to development, testing, and production.
How can I improve the performance of my Jest tests?
To improve performance, consider using the --runInBand
