Conducting Browser Compatibility Tests

github.com/jeremylongshore/claude-code-plugins-plus-skills

This skill enables cross-browser compatibility testing for web applications using BrowserStack, Selenium Grid, or Playwright. It tests across Chrome, Firefox, Safari, and Edge, identifying browser-specific bugs and ensuring consistent functionality. It is used when a user requests to "test browser compatibility", "run cross-browser tests", or uses the `/browser-test` or `/bt` command to assess web application behavior across different browsers and devices. The skill generates a report detailing compatibility issues and screenshots for visual verification.

Overview

This skill automates cross-browser compatibility testing, ensuring that web applications function correctly across various browsers and devices. It leverages BrowserStack, Selenium Grid, and Playwright to execute tests and identify browser-specific issues.

How It Works

  1. Configuring Browser Matrix: Defines the target browsers (Chrome, Firefox, Safari, Edge), versions, operating systems, and device configurations for testing.
  2. Generating Cross-Browser Tests: Creates and configures tests to run across the defined browser matrix, handling browser-specific quirks and setting up parallel execution for efficiency.
  3. Executing Tests: Runs the tests in parallel using BrowserStack, Selenium Grid, or Playwright, capturing screenshots and logs for analysis.
  4. Generating Compatibility Report: Compiles a detailed report highlighting any compatibility issues, including screenshots and error logs, for easy identification and resolution.

When to Use This Skill

This skill activates when you need to:

  • Ensure a web application functions correctly across different browsers and devices.
  • Identify browser-specific bugs or compatibility issues.
  • Automate cross-browser testing as part of a CI/CD pipeline.

Examples

Example 1: Testing a new feature

User request: "Test browser compatibility for the new shopping cart feature."

The skill will:

  1. Configure the browser matrix with the latest versions of Chrome, Firefox, Safari, and Edge.
  2. Execute tests specifically targeting the shopping cart functionality across the configured browsers.
  3. Generate a report highlighting any compatibility issues encountered with the shopping cart feature, including screenshots.

Example 2: Regression testing after an update

User request: "/bt"

The skill will:

  1. Use the default browser matrix (or a previously defined configuration).
  2. Run all existing tests across the configured browsers and devices.
  3. Provide a comprehensive report detailing any regressions or new compatibility issues introduced by the recent update.

Best Practices

  • Configuration: Clearly define the target browser matrix to ensure comprehensive testing.
  • Test Design: Write tests that are robust and cover a wide range of user interactions.
  • Report Analysis: Carefully analyze the generated reports to identify and address compatibility issues promptly.

Integration

This skill can be integrated into a CI/CD pipeline using other tools to automate cross-browser testing as part of the deployment process. It can also work with issue tracking systems to automatically create tickets for identified compatibility bugs.
