Instead of requiring all frames in the subtree to receive a particular
event, we rely on the browser's definition of load and DOMContentLoaded.
This changes logic in a few edge cases:
- Some browsers do not emit load event upon window.stop() at all.
- DOMContentLoaded does not wait for subframes, so they might not be
ready when passing `{ waitUntil: 'domcontentloaded' }`.
`networkidle` preserves the old logic.
It could be that iframe was blocking some event, like load or networkidle,
and we never updated the lifecycle after the iframe was detached. This
lead to goto and other navigation commands to never resolve.
This patch introduces 109 "#smoke" tests - a subset of tests that makes
sure that basic Playwright functionality works. This set is loosely
defined; feel free to add/remove tests to the set. The only goal is to
keep this set minimal & fast to run.
I tried to pick tests so that various parts of Playwright functionality
are exercised.
This patch moves service tests to use experimental grid.
Test changes:
- `proxy.spec.ts` - proxy setup is not supported at all in service mode.
This is because we already use proxy for browsers to properly resolve
localhost.
- `har.spec.ts` - tests disabled since connection port is different.
