Encountering the Jest error EMFILE: Too Many Open Files
can disrupt your testing environment. However, you can resolve this issue by making adjustments to your Jest configuration in the jest.config.js
file.
To mitigate the ‘EMFILE: Too Many Open Files’ error, consider adding the following configuration:
// jest.config.js

, reducing the number of open files during testing. This adjustment should help alleviate the EMFILE: Too Many Open Files
