Key Differences in Syntax and Usage
While both Selenium and Playwright aim to achieve similar goals, there are notable differences in their syntax and usage.
Selenium follows a traditional WebDriver approach, where you interact with elements on a web page using various methods such as findElement, click, and sendKeys.
This approach is well-established and familiar to many testers, making it easy to adopt for existing Selenium users. However, it can sometimes lead to verbose and repetitive code, especially when dealing with complex web pages.
On the other hand, Playwright takes a more modern and streamlined approach to automation. It provides a fluent and concise API that allows you to write expressive and readable code.
Playwright's API includes intuitive methods like click, type, and waitForSelector, which simplify common automation tasks and reduce the amount of boilerplate code required. This approach promotes cleaner code and enhances the maintainability of your test scripts.
Another key difference is how the frameworks handle browser instances. Selenium creates a separate driver instance for each browser session, which can lead to increased memory usage and slower execution times when running tests in parallel.
In contrast, Playwright uses a single browser instance and creates lightweight contexts for each test. This efficient resource management allows Playwright to execute tests faster and with lower resource consumption.
In summary, Selenium follows a more traditional WebDriver approach, while Playwright takes a modern and streamlined approach to automation.
Playwright's concise syntax and efficient resource management make it an attractive choice for teams looking for a more developer-friendly automation framework.
Browser Compatibility and Support
Browser compatibility is a crucial aspect to consider when choosing an automation framework. Both Selenium and Playwright excel in this area, but with some differences.

Additionally, maintaining compatibility with the latest browser versions requires timely updates to the drivers.
Playwright, on the other hand, provides built-in support for major browsers, including Chrome, Firefox, Safari, and Microsoft Edge. Since Playwright is developed and maintained by Microsoft, it ensures seamless compatibility with the latest browser versions. This eliminates the need for third-party drivers and reduces the chances of compatibility issues.
In terms of mobile testing, Selenium offers support for mobile browsers through the Appium framework, which integrates with Selenium WebDriver. This allows you to write tests that target both desktop and mobile browsers using a single framework.
Playwright, on the other hand, currently focuses primarily on desktop browsers and does not provide native mobile testing capabilities out of the box.
In summary, both Selenium and Playwright offer excellent browser compatibility, but Playwright's built-in support for major browsers and seamless compatibility with the latest versions give it a slight edge in this area.
