Moli (https://github.com/lexmount/moli) is a Rust headless browser with V8 and Stylo, served over CDP. The helper is a thin CDPBrowser subclass like Lightpanda: it self-launches `moli serve` on a free port, or attaches to an explicit endpoint. Moli runs without --layout on purpose: with --layout element geometry is frozen on first read and only a screenshot refreshes it, which breaks waitForVisible/waitForText. Presets pin synthetic input, layout 'real' and no screenshots, since the runtime probe would otherwise pick coordinate input that Moli rejects in this mode. - shared webapi suite: 289 passing, 50 pending; 6 tests skipped with verified reasons (clickXY, upload MIME type, link color) - 19 acceptance scenarios tagged @Moli, including gherkin features - CI workflow pinned to v1.1.17 with SHA256 check - docs: alternative browsers, installation, README, helper reference Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
The mocha adapter uses Mocha.utils.inherits, removed in mocha 12. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

Adds an experimental
Molihelper driving Moli, a Rust headless browser (V8 + Servo's Stylo) served over CDP. Implemented likeLightpanda: a thinCDPBrowsersubclass that pins presets and manages themoli serveprocess (self-launch on a free port, attach viaendpoint, or courtesy-attach to:9222).Why no
--layoutWith
moli serve --layout, element geometry is a snapshot frozen on first read. After a DOM change (adisplaytoggle, a newly appended node) boxes stay 0×0 untilPage.captureScreenshotrebuilds the layout. That brokewaitForVisibleandwaitForText(35 webapi failures). Default mode uses placeholder boxes that followdisplayandvisibilitylive, so visibility checks work and only 6 tests need skipping.The runtime layout probe reports
real, because Stylo computes styles, and would pick CDP coordinate input, which Moli rejects without layout. So the helper pins the presets:input: 'synthetic',capabilities.layout: 'real',capabilities.screenshot: false.Changes

Versions are the CI-pinned ones (Lightpanda 1.0.0, Obscura 0.2.2, Chrome 144 headless). The iteration loop fills and submits a form, ticks a checkbox, selects an option, clicks a link and reads text; 3 rounds of 30 iterations each.
