[rustdoc] Make the buttons remain when code example is clicked Follow-up of https://github.com/rust-lang/rust/pull/125779. One current issue we have with "run" button and the newly added copy code button is that if you're on mobile devices, you can't use them. I took a look at how `mdbook` is handling it and when you click on a code example, they show the buttons. I think it's a really good idea as if you want to copy the code on your mobile device, you will click on it, showing the buttons. Feature can be tested [here](https://rustdoc.crud.net/imperio/click-code-example/foo/struct.Bar.html). r? `@notriddle`
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
