No tracing available in BrowserContext #777

Closed mostor-v closed 3 years ago

mostor-v commented 3 years ago

Hi I'm trying to use trace viewer with jest-playwright but can't start it.

I was trying to start as await context.tracing.start({screenshot:true}) but got an error that property 'traing' doesn't exists under BrowserContext. Also i was trying to run it like - await (browser as ChromiumBrowser).startTracing(page, {screenshot:true}) but generated tracing is corrupted.

As i see tracing available in playwright\types\BrowserContext but not available in playwright-core\types\BrowserContext which is used by jest-playwright context

jest-playwright = 1.7.0 playwright = 1.13.0

startTracing is different from .tracing, see here: https://playwright.dev/docs/api/class-browser#browser-start-tracing

In your case, its probably because not a recent playwright-core version is used, try to install the latest one via npm install playwright-core@latest.

Closing as #746 is a feature request for tracing and its already in the works.

@mxschmitt i can't understand how i can update playwright-core in separate from jest-playwright?After npm install playwright-core@latest my browser context still work with playwright-core from jest-playwright-preset package. I've deleted all node_modules, re-installed all packages 100500 times but still can't use tracing feature.
