Some very quick research using Gemini, asking it for a list of available tech.

Here's a comprehensive list of web technologies commonly used for automated testing to control web browsers.

Mainstream Frameworks

Selenium WebDriver: The industry standard, offering support for multiple programming languages (Java, Python, C#, Ruby, JavaScript) and browsers.
Playwright: A relatively newer framework, known for its speed, reliability, and cross-browser compatibility. It supports multiple programming languages as well.

Headless Browsers

Puppeteer: A Node.js library for controlling Chrome or Chromium. It's particularly useful for server-side rendering and scraping.
Playwright (Headless): Can also be used in headless mode for efficient testing without a visible browser interface.
Cypress: A JavaScript-based end-to-end testing framework that can run tests in headless mode.

WebdriverIO: A Node.js-based framework built on top of Selenium WebDriver.
Appium: For mobile app testing, but can also be used for web app testing on mobile devices.
TestCafe: A JavaScript-based end-to-end testing framework with built-in waiting mechanisms and automatic retries.
Robot Framework: A generic test automation framework that can be used for web testing with Selenium library.

Browser Compatibility: Ensure your chosen tool supports the browsers you need to test (Chrome, Firefox, Safari, Edge, etc.).
Programming Language: Select a tool that aligns with your team's preferred language.
Test Environment Setup: Consider using cloud-based testing platforms like BrowserStack or Sauce Labs to simplify environment setup and cross-browser testing.
Test Automation Framework: Design a robust framework to organize tests, manage test data, and report results efficiently.
Continuous Integration/Continuous Delivery (CI/CD): Integrate your automated tests into your CI/CD pipeline to ensure code quality and early detection of issues.

By carefully selecting and combining these technologies, you can create efficient and reliable automated testing solutions for your web applications.
