rustdoc: remove redundant item kind class from `.item-decl > pre`
This class originated in the very first commit of `rustdoc_ng`, and was used to add a color border around the item decl based on its kind.
4fd061c426/src/rustdoc_ng/html/static/main.css (L102-L106)
The item decl no longer has a border, and there aren't any kind-specific styles in modern rustdoc's rendering of this UI item.
Most of this PR is updating test cases so that they use `item-decl` to find the `<pre>` tag instead of relying on the fact that the class name had `rust {kind}` in it while other `<pre>` tags only had class `rust`.
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
