How to use Playwright to interact with Metamask?

Question

I'd like to automate interactions with Metamask using Playwright and Python, but I don't understand exactly how the extension is controlled. When I open the browser the extension may or may not be configured. Each time the extension is requested, it opens a new page in the handler array.

How do I master the extension, load correctly, configure networks, open at the right time, know which handler is correct, approve or reject transactions and everything else?

Any full tutorial? Course? Book?

Answer 1

There is a great tool (e2e testing framework) for automating metamask (using playwright or cypress, what ever you prefer) which I'm using - it's called synpress

It seems to be very well maintained past few years and is being continuously developed.

They have great repositories with examples for setup: github.com/drptbl/synpress-examples

and CI: github.com/Synthetixio/synpress/tree/dev/.github/workflows

Sadly, it's not written in Python, but JavaScript (also supports TypeScript).
Hope this helps.
