Mocking MQTT.js in system tests via Playwright

[visini]

I've written a blog post to demonstrate how to mock MQTT.js via Playwright in system tests.

Hope it's helpful for somebody

Hi @visini and thanks for your article. It could be my opinion but I don't think having a broker adds so much overhead at all, I suggest you to give a look for example to aedes-cli package that's a package I used on mqttjs for browser e2e tests :)

@robertsLando fascinating, thank you – I will definitely have a look, this looks straightforward indeed 👍
