SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill requires bidiwave, pytest, pytest-asyncio, and includes references (resource) and assets (resource) components.

What problem does it solve?

This skill solves the fragmentation of browser automation by providing a unified, W3C-standardized interface for testing across Chrome, Firefox, and Edge without relying on proprietary drivers or non-standard protocols.

Core Features & Use Cases

  • Unified Protocol: Execute tests using the W3C WebDriver BiDi standard, ensuring consistent behavior across major browsers.
  • Advanced Interaction: Perform complex tasks like network interception, preload script injection, and RemoteValue pattern matching for type-safe JavaScript evaluation.
  • Use Case: A QA engineer needs to verify that a web application's authentication flow works identically on Firefox and Chrome; this skill allows them to write a single test suite that executes against both browsers using native BiDi support.

Quick Start

Use the bidiwave cross-browser skill to connect to a local browser endpoint and execute a test script that validates the page title across Chrome, Firefox, and Edge.

FAQPage Schema
How does WebDriver BiDi protocol handle cross-browser testing across Chrome, Firefox, and Edge?

WebDriver BiDi provides a W3C-standardized interface for cross-browser testing, ensuring consistent behavior across Chrome, Firefox, and Edge without relying on proprietary drivers. It manages browsing contexts and event streaming natively to execute unified automation tests.

Can I perform network interception and preload script injection using Python cross-browser automation?

Yes, you can perform network interception and preload script injection using Python cross-browser automation. The bidiwave library leverages the W3C WebDriver BiDi protocol to execute advanced interactions like script evaluation and network mocking across major browsers.

Do I need a BiDi-capable browser endpoint to run cross-browser automation tests with pytest?

Yes, you need a BiDi-capable browser endpoint to execute cross-browser automation tests with pytest. The testing framework uses the bidiwave Python library to connect to this endpoint and manage browsing contexts and event streaming.

What is RemoteValue pattern matching in WebDriver BiDi script evaluation?

RemoteValue pattern matching is a feature in WebDriver BiDi script evaluation that enables type-safe JavaScript evaluation. It allows you to verify and match complex data structures returned from the browser during cross-browser automation testing.

How do I write a single test suite that executes against both Firefox and Chrome using native BiDi support?

To write a single test suite for Firefox and Chrome, use the bidiwave library with pytest to execute tests using the W3C WebDriver BiDi standard. This unified protocol ensures the authentication flow and other behaviors work identically across browsers.

Why does cross-browser testing fragment without a unified protocol like W3C WebDriver BiDi?

Cross-browser testing fragments without a unified protocol because traditional methods rely on proprietary drivers or non-standard protocols. W3C WebDriver BiDi solves this by providing a standardized interface for consistent behavior across Chrome, Firefox, and Edge.
