1 - Architecture:
Selenium 3 uses the WebDriver API directly to interact with browsers.
Selenium 4 introduces a new architecture called the W3C standard WebDriver which helps in better communication between the WebDriver and browsers.
2) Relative Locators:
Selenium 4 introduces Relative Locators which provide simpler and more intuitive ways to locate elements relative to other elements.
Selenium 3 does not have built in support for Relative Locators.
3) Improved Selenium Grid:
Selenium 4 comes with an improved Selenium Grid with better security options, easier scaling, and automatic updates.
Selenium 3 Selenium Grid lacks some of these advanced features.
4) New DevTools API:
Selenium 4 includes the new DevTools API which provides access to more browser functionalities for debugging and testing.
Selenium 3 does not have direct access to the DevTools API.
5) Streamlined Selenium IDE:
Selenium 4 includes a revamped Selenium IDE with better usability and improved features.
Selenium 3's Selenium IDE was less user friendly and had limited capabilities.
6) Improved Performance:
Selenium 4 offers improved performance and stability compared to Selenium 3, making test execution faster and more reliable.
Selenium 3 may encounter performance issues when handling complex test scenarios.
7) Enhanced Error Handling:
Selenium 4 provides enhanced error handling mechanisms, making it easier to debug tests and identify issues.
Selenium 3 may have limited error handling capabilities, leading to more challenging troubleshooting.
8) Compatibility:
Selenium 4 ensures better compatibility with the latest browser versions and features compared to Selenium 3.
Selenium 3 may face challenges in supporting newer browser functionalities.
9) Documentation and Community Support:
Selenium 4 comes with updated documentation and stronger community support, making it easier for users to find resources and help when needed.
Selenium 3's documentation and community support may be outdated or less accessible.
10) Integration with Tools:
Selenium 4 offers improved integration with popular automation tools and frameworks, enhancing the overall testing ecosystem.
Selenium 3 may have limited integration options with newer testing tools and technologies.
11) Parallel Testing Capabilities:
Selenium 4 provides enhanced parallel testing capabilities, allowing users to execute tests more efficiently across multiple browsers and platforms.
Selenium 3's parallel testing features may not be as robust or easy to set up.
12) Updates and Maintenance:
Selenium 4 is actively maintained and regularly updated with new features and improvements.
Selenium 3 may have fewer updates and maintenance support, potentially leading to compatibility issues over time.
13) Browser Support:
Selenium 4 offers better support for newer browser versions and technologies, ensuring smoother test execution.
Selenium 3 may struggle to handle the latest browser updates and features.
14) Integration with CI/CD Pipelines:
Selenium 4 provides better integration with CI/CD pipelines, enabling seamless automation testing within the continuous integration workflow.
Selenium 3 may have limitations in integrating effectively with modern CI/CD tools and practices.
15) User Interface:
Selenium 4 has a more user friendly interface with improved navigation and functionality.
Selenium 3 may have a slightly outdated or less intuitive user interface.
These points highlight the key differences between Selenium 3 and Selenium 4, showcasing the advantages and improvements that the latest version offers to students looking to enhance their automation testing skills. A training program focusing on Selenium 4 would equip students with the most up to date knowledge and skills required for successful test automation implementation.
