feat: Implement using Playwright for taking screenshots in reports #25247

kgabryje · 2023-09-10T11:50:16Z

SUMMARY

Implements SIP-98.

If a feature flag PLAYWRIGHT_REPORTS_AND_THUMBNAILS is on, use Playwright instead of Selenium to take screenshots of dashboards and charts when preparing reports and thumbnails.

BEFORE/AFTER SCREENSHOTS OR ANIMATED GIF

The change should be visible when running a report on a dashboard that contains deck.gl charts.
Before:

After:

TESTING INSTRUCTIONS

Enable PLAYWRIGHT_REPORTS_AND_THUMBNAILS ff
Setup reports (https://superset.apache.org/docs/installation/alerts-reports/)
Create a report and verify that the screenshot was taken correctly. If possible, also verify using deck.gl charts
Generate thumbnails (https://superset.apache.org/docs/installation/cache/#caching-thumbnails)
Verify that thumbnails screenshots were taken correctly (including deck.gl charts)
If the feature flag is disabled, the screenshots should be taken using Selenium - no changes.

Exciting stuff. First pass, comments mainly related to whether or not we should add the deps as required vs optional. I also have some unrelated grievances with how the current Allerts & Reports feature handles errors, but let's chat about those separately (=this is a good opportunity to think about improving this as we're refactoring the code that detects whether or not the page has rendered).

I think this should probably go into the dev, integration or test deps

Could you explain why? Isn't reports one of the basic flows? Or maybe I misunderstand the purpose of those files

The fact that it's marked as an optional dependency in setup.py IMO means it should not be in base.txt. Was this entry added by hand, or via pip-compile-multi? I assume we'd need to change requirements/base.in as follows to autogenerate this:

-e file:.[playwright]

Should we move this into an optional dep until selenium is deprecated?

Where are the optional deps located?

That's a good idea. @kgabryje in extras_require below.

Thanks, moved

What's the correlation between the local overwrite config and installing playwright?

There isn't, it's a leftover from my tests in POC phase 🤦 updated

@eschutho Actually, now that we moved playwright to optional packages, I think we should make installing additional deps conditional. Do we have an established pattern for that?

you can move this import down to the authenticate_playwright_browser_context method if you get errors on it not loading when the feature flag is not on.

I put the import behind a feature flag check - I couldn't move it to the method as it was used for typing that method

Scratch that, importing feature_flag_manager causes a circular import

should we try to dry this up from the other authenticate method?

I think this is good to go after we decide on how to handle this new dependency.

I think we should be consistent in either having separate func overrides in the constructor if the authenticate methods are separate, or merge them so as to only support one screenshot mechanism.

LGTM, thanks for all the hard work here! ❤️

Looks great @kgabryje!

@kgabryje I left a comment on a part that may break existing functionality. I'd suggest let's see if we can quickly fix forward.
