Overview
As Selenium was in the market for a long time and provides numerous benefits, Cypress is actually a new age tool that is even more effective and amazing in some perspectives. Playwright is basically used for a perfect end-to-end testing and even has its own benefits. In the modern era, Zebrunner experts study Selenium, Cypress, and Playwright in distinction to know more about all their benefits and limitations.
Playwright overview
Playwright is basically an open-source automated end to end testing pattern for web apps, designed by Microsoft organisation and introduced to the market on January 31, 2020. It already earned fame among prominent programmers and other web developers.
Playwright is highly suitable for cross-platform testing. It aids all modern day providing engines involving WebKit, Firefox and Chromium. With amazing support of Playwright, you can even scrutinise, verify and examine on macOS, Windows, and Linux domestically or by CI, if headless or also headed. Playwright API is certainly available in JavaScript, TypeScript, .NET, or Python.
Playwright facilitates reliability by watching for action components before taking actions. Mostly characteristics like test retries, action trace capture, video and screenshot abilities are in existence to reduce flakiness.
Each proper test implemented with Playwright works within its own extraordinary browser backdrop, just like a novel browser file. This facilitates wholesome study isolation aloof of any extra overhead expenses. We will study Playwright Vs Selenium here.
Selenium overview
The tale of the Selenium project in 2004.
Selenium is truly an open-source testing pattern executed for automation testing of web apps around several prominent platforms and web browsers. Along with Selenium, one can use apps across larger browsers utilising different programming languages namely Java, ScriptJava, C#, Python, Ruby or PHP.
Testers make use of Selenium’s pattern to run tests parallely across different browser cases, pacing up the entire testing procedure. All thanks to parallel implementation, the testing period in your CD or CI pipeline can end comparatively quicker, thereby speeding up the entire development process.
Selenium includes various different tools. Let’s unleash the tool suite in a meticulous manner.
Selenium WebDriver
This powerful library facilitates API call via code, implementing commands on the selected browser. One can use Selenium locators to seek elements, designing test cases and integrating with them by making use of WebDriver APIs. Explicit browser interaction turns WebDriver quicker than Selenium Remote Control or (RC), with different drivers for various browsers explaining your script.
Selenium IDE
This prominent tool permits its users to edit, replay and record test methods and techniques. Because it is an add-on for Chrome, Edge, and Firefox the IDE makes the development and execution of automated tests simple without coding needs. With Selenium IDE, you can keep browser executions like clicking components and filling applications, consequently making them replying to study web app features. In addition to it, IDE even ensures script editing, affirmation inclusion to study application character and script export to forms like Java, HTML, Python or C#.

Selenium Grid
This amazing tool allows tests to run on various browsers and machines at the same time. Selenium Grid is important for big test suites that require fast execution by performing tests on various machines, browsers and operating systems. It consists of a powerful central hub and many nodes, dispersing test execution on different surroundings. Users have a hub to handle test examination on linked nodes, each symbolising various performing systems, versions and web browsers. Nodes implement tests as managed by the hub, sharing back results for totalling.
Cypress overview
Began in 2014, Cypress.io modernised web testing by co-integrating it simply into the web browser for current age, powerful testing. Basically created as an amazing tool, it later grew into a broadly adopted platform, implemented by companies like Disney, Slack and Netflix. Cypress provides a cost free, open-source app and a Cypress Cloud that is subscription based, giving wholesome testing tools and other significant actionable views.
Cypress is a highly front-end testing tool for advanced web apps, utilising JavaScript and customising in end-to-end testing via the Mocha pattern. During recent years, Cypress has turned out to be a robust automation review and a feasible option to Selenium. Let us have a deep study of Playwright Vs Cypress.
Among Cypress’s amazing features is its popular setup method. Most crucial components for designing test cases are mixed within Cypress, reducing the requirement for various dependencies. Functioning within the browser, Cypress implements test suites quickly, more than frameworks as Selenium. The Cypress group has a linked Chai assertion library supporting the popular Mocha framework, making it convenient to execute test cases in a BDD style.
Cypress automation softwares checks crucial pain problems encountered by engineers and other QA developers when they test advanced applications.
Distinction between Playwright, Selenium and Cypress
| Characteristics | Playwright | Selenium | Cypress |
| Test runner | Convenient, can be downloaded by npm or VS Code extension | Different runners involving Selenium Grid, JUnitTestNG, Selenium WebDriver. | Runner having real reloading and debugging in an joint or integrated GUI |
| Language Support | TypeScript, .NET, Python, Java, JavaScript | JavaScript, Java, C#Ruby, Python PHP. | JavaScript |
| Browser support | Firefox, Microsoft Edge or Chromium, Safari or WebKit, Google Chrome. | Edge, Chrome, Safari, IE, Firefox, Opera. | Mozilla Firefox, Google Chrome, Apple Safari, and Microsoft Edge. |
| Parallel execution | Yes, this is possible here. It has built-in support for parallel implementation | It operates with Selenium Grid | Yes, it does by CI and Cypress Dashboard. |
| Key strengths | Advanced API, cross-browser support, designed retries, robust management of async plans. | Wide browser and language aid, a great robust ecosystem | Simple setup, quick execution, real-time review. |
| Flakiness Handling | waitForSelectorAuto-wait, re uses to manage flaky tests | Needs consistent selectors, direct waits, go for retry logic | Auto-wait, timeout management and retry to eliminate flakiness |
| Video recording | Understandable video recording, with alternatives to remain only on failure | Extensions needed for video shoot | Auto video kept for records of test runs |
| Iframe handling | It has FrameLocator method | Switch along frames utilising switchTo().frame() techniques. | Needs plugin for iFrame handling |
Conclusion
This blog has shared some of the most amazing differences between Playwright, Cypress and Selenium. There are distinctive features and points of importance. You can go for your suitable option without any confusion.
