Surya Hebbar commented on IMPALA-12364:
---------------------------------------

Before implementing further features or increasing complexity, it is required 
to identify problematic patterns. As currently no testing framework exists for 
testing JavaScript within the project, it needs to be integrated into Jenkins 
pipeline as a parallel test job.

After research, Jest and Vitest were identified as some frameworks which are 
widely supported and used by the community. Both require integrating through 
NodeJS packages. ESLint can be used to identify problematic patterns in code by 
having a set of rules in .eslintrc.

 

This can help run tests easily during further development of the webUI.

 

For integrating a parallel job in jenkins, shell scripts for installing NodeJS 
dependencies and tests in NodeJS are to be written.
