Only load one CSS theme by default This is a tweaked version of #103971 that uses `document.write` to create the stylesheet link at startup, avoiding a FOUC during page navigation. It also rebases the PR, making it work with the new hashed filenames. Fixes #82614 Preview: http://notriddle.com/notriddle-rustdoc-demos/load-only-one-theme-v2/std/index.html
The tests present here are used to test the generated HTML from rustdoc. The goal is to prevent unsound/unexpected GUI changes.
This is using the browser-ui-test framework to do so. It works as follows:
It wraps puppeteer to send commands to a web browser in order to navigate and test what's being currently displayed in the web page.
You can find more information and its documentation in its repository.
If you need to have more information on the tests run, you can use --test-args:
$ ./x.py test tests/rustdoc-gui --stage 1 --test-args --debug
If you don't want to run in headless mode (helpful to debug sometimes), you can use
--no-headless:
$ ./x.py test tests/rustdoc-gui --stage 1 --test-args --no-headless
To see the supported options, use --help.
Important to be noted: if the chromium instance crashes when you run it, you might need to
use --no-sandbox to make it work:
$ ./x.py test tests/rustdoc-gui --stage 1 --test-args --no-sandbox
