What Is Selenium?

Selenium is probably going probably the most well-established instrument within the subject of automated browser testing (over 35,000 corporations reported utilizing Selenium in 2025).

Initially launched in 2004, it has grown to develop into the de facto trade commonplace for practical testing of internet purposes. Whereas a lot of the present instruments for automated testing characterize one product, Selenium represents a set of instruments:

• Selenium WebDriver: The underlying API upon which builders write check scripts and discuss to browsers.
• Selenium IDE: A record-and-playback instrument which may be utilized even by non-tech customers to construct easy check circumstances.
• Selenium Grid: A system for working assessments in parallel on quite a few machines, which is critical for in depth software program testing.

Within the background, Selenium is definitely applied on prime of the WebDriver protocol. It interprets check instructions into JSON, sends them over HTTP to browser drivers, after which makes them execute inside the browser. This structure has labored nicely for generations, although it does come at some efficiency expense.

What distinguishes Selenium is its protection. Selenium affords assist for almost all of the distinguished programming languages (Java, Python, C#, PHP, and JavaScript) and all the highest browsers (Chrome, Firefox, Safari, Edge, and even Web Explorer).

With twenty years of utilization, it additionally has an enormous group, in depth CI/CD pipeline integration, and an abundance of documentation and tutorials.

What Is Playwright?

Constructed by Microsoft and made obtainable in 2020, Playwright was created with fashionable internet growth in thoughts to unravel loads of the problems testers have been going through when making use of Selenium for browser automation.

Architecturally, Playwright takes a special method. As an alternative of utilizing the WebDriver protocol and HTTP requests, it communicates with browsers via a long-lived WebSocket connection.

Playwright runs on the three most used browser engines — Chromium, Firefox, and WebKit — so it targets Chrome, Edge, and Safari. Playwright additionally boasts strong cellular emulation and experimental assist for testing precise Android units.

By way of programming languages, Playwright runs on JavaScript, TypeScript, Python, Java, and .NET, that are probably the most used growth stacks immediately.

Playwright vs. Selenium: Key Characteristic Comparability

Playwright and Selenium each try to unravel the identical downside — enabling automated browser testing — however in pretty other ways. Allow us to study their variations via the options most important to growth groups all through the software program growth life cycle.

Ease of Setup and Use

Getting Selenium up and working usually entails a number of steps. You’ll want to put in the proper browser drivers, generally a standalone server, and configure all the things so the check scripts can discuss to the browser.

This flexibility is certainly highly effective, but it surely comes at the price of added complexity, particularly for newcomers.

Playwright is simpler in its nature. As soon as put in, it mechanically downloads the browsers it wants. No further server setup or driver setup is required, so you may write and execute assessments straight away.

For groups that want quick onboarding and minimal configuration, Playwright is the clear winner right here.

Language Help

Selenium helps nearly all the prime programming languages, together with Java, Python, C#, Ruby, PHP, Perl, and JavaScript. That makes it an incredible slot in organizations the place growth groups use various stacks.

Playwright has fewer languages supported, but it surely selects probably the most extensively used ones: JavaScript/TypeScript, Python, Java, and .NET. For many fashionable internet purposes, this checklist is greater than acceptable.

Browser and Platform Help

IE assist is lacking, but it surely compensates via sturdy cellular emulation assist and experimental Android real-device assessments. For contemporary internet growth, this normally covers all the things wanted.

Pace and Efficiency

One among Playwright’s most important promoting factors is pace. As a result of it makes use of a persistent WebSocket connection to speak with browsers, there’s much less back-and-forth in comparison with Selenium’s WebDriver protocol, which sends instructions as JSON over HTTP.

This design distinction results in Playwright not solely being sooner but in addition extra environment friendly underneath real-world masses.

Selenium’s method has been a reliable choice for years, however further communication overhead bogs down assessments, particularly when scaled up.

Check Reliability (Flakiness)

Flaky assessments are a nightmare for each QA staff. With Selenium, builders manually deal with synchronization utilizing express waits or third-party libraries. If not correctly managed, assessments will fail intermittently.

Playwright reduces the problem with auto-waiting inbuilt. The check framework mechanically waits for parts to develop into obtainable earlier than dealing with them, which results in fewer false failures and extra secure check runs.

API Design and Developer Expertise

Selenium’s API is highly effective however can really feel verbose. Writing assessments normally requires extra traces of code to deal with waits and synchronizations.

Playwright boasts a cleaner, fashionable API. Clicking, hovering, or filling out types wants fewer traces of code. For builders who like to jot down quick and expressive code, Playwright is a greater different.

Neighborhood and Ecosystem

Being available on the market for almost twenty years, Selenium has one of many largest check automation communities.

There is a gigantic library of tutorials, libraries, and integrations with CI/CD instruments. In case you are caught someplace, it’s seemingly that somebody has already found out tips on how to remedy it.

The Playwright group is smaller however rising very quick. Backed by Microsoft, it’s being actively contributed to, and fashionable frameworks are more and more integrating with it.

Superior Options

Essentially the most spectacular a part of Selenium is Selenium Grid, which allows distributed and parallel check execution on a number of machines. It’s extremely useful for giant groups and enterprise testing.

Playwright comes with a set of superior capabilities out of the field: screenshots, video seize, community interception, gadget and geolocation simulation, and even timezone manipulation.

They arrive with no further plugins, which is why Playwright is very well-suited for modern, feature-rich internet purposes.

Check Runner & Framework Integration

Selenium doesn’t have a check runner inbuilt, however is suitable with JUnit, TestNG, NUnit, and Pytest frameworks. That flexibility permits groups to pair it with no matter runner most closely fits their workflow.

Playwright has a built-in check runner, which affords an built-in method for many who like having all the things bundled collectively. It’s nonetheless suitable with Jest, Mocha, Jasmine, and Pytest, nevertheless.

Evaluating Playwright and Selenium: At a Look
