| # The `rustdoc-gui` test suite | 
 |  | 
 | > **FIXME**: This section is a stub. Please help us flesh it out! | 
 |  | 
 | This page is about the test suite named `rustdoc-gui` used to test the "GUI" of `rustdoc` (i.e., the HTML/JS/CSS as rendered in a browser). | 
 | For other rustdoc-specific test suites, see [Rustdoc test suites]. | 
 |  | 
 | These use a NodeJS-based tool called [`browser-UI-test`] that uses [puppeteer] to run tests in a headless browser and check rendering and interactivity. For information on how to write this form of test, see [`tests/rustdoc-gui/README.md`][rustdoc-gui-readme] as well as [the description of the `.goml` format][goml-script] |
