[Question] PhantomJS

[sakaia]

The frontend uses PhantomJS.
Regrettably, the PhantomJS will stop development.
Of course, kubernetes/pipelines used the PhantomJS in build time only.

Is there any plan to move from PhantomJS?
If so, which package you will plan to use?

Reference

• frontend/Dockerfile
• Archiving the project: suspending the development #15344
• update dockerfile and add build step of frontend #567

Thanks @sakaia for raising the question.

I took this opportunity to investigate a little. Here's what I found:

• We used to use backstopjs for visual regression testing (which used phantomjs internally, but no longer now): https://github.com/kubeflow/pipelines/blob/master/frontend/backstop.ts
• But somehow after main maintainer for kfp frontend changed a few times, we simply don't know or use it any more.

Backstop js itself has removed phantomjs support in a later release: garris/BackstopJS#772 (comment)

We have a few options:

1. Upgrad backstop js and restore backstop js tests
2. Just delete them

So far, I don't feel we have a strong need for visual regression testing, so I will go with deletion to simplify maintenance.

And FYI, for UI integration testing, we are using selenium (I'm thinking about replacing it with cypress, puppeteer or https://github.com/microsoft/playwright later, but not now).

Sent above PR to remove backstop js, and thus also dependency of phantom js.
