- Example:
WebElement element = driver.findElement(withTagName(“button”).below(header));
3. Enhanced Selenium Grid
- Redesigned for better scalability and stability.
- Supports Docker, making it easy to deploy in cloud-based environments.
- Grid Modes:
- Standalone
- Hub and Node
- Fully Distributed
Comparison of Selenium 4 Grid Modes
| Mode | Best Use Case | Scalability |
| Standalone | Single instance testing | Low |
| Hub and Node | Centralized management with multiple nodes | Medium |
| Fully Distributed | Cloud-based deployments, large-scale tests | High |
4. DevTools Protocol Integration
- Introduces support for Chrome DevTools Protocol (CDP).
- Offers advanced debugging, network monitoring, and performance testing capabilities.
5. Upgraded IDE
- Selenium IDE now supports parallel execution and plugins.
- Enhances usability for beginners with an improved GUI.
