Sharing Playwright/Puppeteer instance?

[jakobrosenberg]

Is there a straightforward approach to this through shared workers?

I assume you'll launch the instance in the shared worker.

Could you elaborate on what test workers need to do with this shared instance?

I'll confess that I'm completely out of my element when it comes to shared workers. What I'd like to do is have a number of test files all share the same Playwright browser instance.

I got the impression that it's doable from the quote below, but I have no idea if it's a straightforward task.

Not sure what to build? Previously folks have expressed a desire for mutexes, managing Puppeteer instances, starting (database) servers and so forth.

There's been some discussion here: #2703 (comment)

The problem I think is that you need some way to do remote procedure calls from the test worker to the shared Puppeteer instance. You can't share the full Puppeteer API directly.

You can't share the full Puppeteer API directly.

I feared you might say that. 😅
