What it does (after installation)
Vibium is a lightweight WebDriver BiDi browser automation engine (10MB vs 300MB for Playwright).
- 16 typed assertion kinds: element presence, text content, attribute values, computed styles, network responses, accessibility tree, visual diff, etc.
- Multi-step batch pre-validation: validates all steps before executing, preventing mid-sequence failures
- Pixel-perfect visual-diff baselines: screenshot comparison with configurable thresholds
- 14-pattern prompt-injection scanner: scans page content for injection attempts
- 15 semantic element intents:
submit_form, accept_cookies, primary_cta, close_modal, etc.
