We should have a testing framework for the frontend and compute testing coverage if possible as well.

@patzielinski I am interested to work in this issue. Would like to know which testing framework is preferred.

[patzielinski]

Sure. I am not familiar with frontend testing frameworks unfortunately. As long as they are FOSS and easy to review for us, it should work. cc @Nishanth2969 for suggestions on frameworks.
