As a result of Playwright’s built-in cross-browser support, testers may easily perform tests on Chrome, Firefox, and WebKit without the need for any additional settings. Selenium also supports a variety of browsers, however additional driver installations could be necessary. Major browser compatibility is ensured by both frameworks.
Language Support
Multiple programming languages are supported by Playwright out of the box, which is helpful for teams with a variety of skill sets. Even while Selenium supports multiple languages, not all of them will have the same libraries and bindings. There is substantial language support in both frameworks.
Performance
Playwright’s strong architecture and effective implementation have helped it become known for its exceptional performance. Compared to Selenium, it offers quicker test execution times and better stability. Playwright’s excellent performance is aided by its effective event-driven design..
Debugging Capabilities
Playwright excels in offering comprehensive debugging capabilities, allowing testers to take screenshots, record videos, and generate trace logs while executing tests. On the other hand, Selenium also provides debugging features, although it may require additional plugins or libraries for advanced debugging functionalities.
Both frameworks empower testers with effective debugging options, ensuring streamlined troubleshooting of test scripts. Furthermore, Selenium benefits from its extensive community support, making it easier to seek assistance and access a wealth of debugging resources.
CI/CD Integration
Playwright has built-in integration with well-known CI/CD platforms including Travis CI, Azure DevOps, and Jenkins. With the help of this integration, testers may add automated tests to their CI/CD pipelines, facilitating continuous testing and accelerating feedback loops.
Selenium also provides strong CI/CD platform integration capabilities. It offers add-ons and extensions for well-known programs like Jenkins, TeamCity, and Bamboo, allowing test automation to be seamlessly integrated into the CI/CD pipeline.
Test Management Tool Integration
Integration with well-known test management solutions like TestRail, Zephyr, and qTest is supported by Playwright. With the help of this integration, testers may manage test cases, monitor test execution, and produce thorough test reports all from within their favorite test management tool.
Similar to Selenium, test management tools can be integrated. Testers can streamline test management and reporting procedures by integrating Selenium test results and execution data into applications like JIRA, TestRail, or QTest by utilizing plugins or APIs.
The productivity and traceability of automated testing are improved by the ability to seamlessly interface with CI/CD pipelines and test management systems, resulting in improved cooperation and simpler processes for development and QA teams.
Real-World Examples
To illustrate the capabilities of Playwright and Selenium, let’s consider two common testing scenarios:
Form Submission:
With Playwright, you can easily automate form submission by accessing form elements, filling in the required fields, and submitting the form. Playwright’s intuitive syntax allows for concise and readable test scripts.
Example:
| const { chromium } = require(‘playwright’); async function submitForm() { const browser = await chromium.launch(); const page = await browser.newPage(); await page.goto(‘https://example.com’); await page.fill(‘#name’, ‘John Doe’); await page.click(‘#submit-button’); await browser.close(); } submitForm(); |
Let’s try to perform the same steps with Selenium for doing a comparison of steps.
Example:
| import org.openqa.selenium.WebDriver; import org.openqa.selenium.chrome.ChromeDriver; public class SubmitForm { public static void main(String[] args) { // Set the path to the chromedriver executable System.setProperty(“webdriver.chrome.driver”, “path/to/chromedriver”); |
// Create an instance of ChromeDriver WebDriver driver = new ChromeDriver(); // Navigate to the website driver.get(“https://example.com”); // Fill in the form field driver.findElement(By.cssSelector(“#name”)).sendKeys(“John Doe”); // Click the submit button driver.findElement(By.cssSelector(“#submit-button”)).click(); // Close the browser driver.quit(); } |
Community Support and User Base
In the testing community, Playwright has made great progress and is becoming more and more well-liked. Because of Microsoft’s strong support, it will continue to develop and receive upgrades. Playwright has a robust community that actively supports its progress despite having a smaller user base than Selenium.
Being a well-known framework, Selenium benefits from a huge and powerful community support network. It has a large user base and has been widely used by testers all around the world. The vast community makes sure that there are plenty of tools, tutorials, forums, and plugins available to help Selenium users.
