To meet the requirements for automation, support for Chrome, Firefox, and Edge, and compatibility with modern JavaScript frameworks, I recommend the following tools:

1. Playwright (Recommended)

Developed by Microsoft, Playwright is currently the top choice for modern web testing.

• Pros: Extremely fast, highly reliable, and supports Chromium (Chrome/Edge), Firefox, and WebKit (Safari) out of the box. It handles modern JS frameworks (React, Vue, Angular) exceptionally well.
• Best for: Developers and QA teams looking for speed and "auto-waiting" features that reduce flaky tests.

2. Cypress

A favorite among Front-end developers for its developer-friendly experience.

• Pros: Excellent debugging tools, real-time reloading, and an intuitive dashboard. It is very easy to set up for local development.
• Limitations: While it now supports Firefox and Edge, its architecture makes it difficult to test across multiple tabs or handle native browser events as effectively as Playwright.

3. Selenium

The industry standard for over a decade.

• Pros: Massive community support and works with almost every programming language (Java, Python, C#, etc.).
• Limitations: It can be slower and requires more manual configuration for "waits" and drivers. It is generally considered more "heavyweight" compared to Playwright.

4. BrowserStack / Sauce Labs (Cloud Platforms)

If you need to test on real devices and older browser versions without maintaining your own infrastructure.

• How it works: You integrate your Playwright/Cypress/Selenium scripts to run on their cloud-hosted browsers.
• Pros: Access to thousands of real mobile devices and browser combinations.
