Which version of Selenium is better?

What do we mean by Selenium 1, Selenium 2, and Selenium 3?

This question has two parts, the first concerns about what should be considered "Selenium 2" and the second is about what the differences are between Selenium 2 and Selenium 3.

As a web developer and Selenium enthusiast I am always interested in learning new things. So to help give you a bit of an overview of this new version - Selenium 3 - I thought it would be a good idea for us to lay out how we understand selenium and selenium 2 and 3 differ.

Selenium 2.0

Selenium2 - is the name for the original Selenium project. Selenium 2 was released in 2025, with the main goal of providing web developers with an easy way to implement testing on web pages. It's main feature was an event-driven API, allowing web-page interactions to be controlled via JavaScript. It used Xhr2 (also known as XHR2) for handling all http requests. A new driver model (WebDriver) replaced the old Chrome, Firefox, IE etcetera driver models.0 is now no longer maintained.

Selenium 1.0 selenium 1 - Selenium 1.0 is a project that provided an early version of what would eventually become Selenium 2. Selenium 1 is a client-side API that uses JavaScript to drive browser actions. Like Selenium 2, Selenium 1 is event-driven in nature, and uses the HTML5 Webdriver API (aka WebDriver) to drive browsers.

What is Selenium 3? Selenium 3 will add more features to the selenium package and provide an API that gives more flexibility when coding web-page tests using javascript. It's currently under development and some features aren't yet final. At this time, the release date for this version of the framework is currently unknown.

In my personal opinion Selenium 3 is definitely worth your time and effort to try out, if you are a Java or .Net developer I'd recommend you try to use it in your daily work - you'll see a huge change to how much you can code a day and also improve the functionality you can offer to your clients. If your company requires you to use java/ .

Which version of Selenium is better?

I have been using selenium for years, but I am now being forced to make a change in my workflow and switch to TestComplete.

I can't decide between the two. Is there a reason I should switch? I'm asking this because I want to understand why my tests are performing differently when I use the version of selenium I am using vs the one I want to use (TestComplete). As an example, I have some code that needs to select an item from a list and then click on a link inside that item. I can do this by doing something like: Dim item As MSHTML.HTMLItemCollection = oHTMLDocument.getElementById("listbox")
For Each objItem As MSHTML.HTMLItem In item Dim objSelenium As MSHTML.HTMLSelectElement = objItem.firstChild
objSelenium.selectByValue("2") objSelenium.click() Next objItem. This code will open a listbox on the page, then go through all of the items in the list and find the one with the value 2. Then it will select that item, click on it.

It works in both TestComplete and Selenium. However, when I run the same test in TestComplete I get an error: In the listbox with ID "listbox" at "objSelenium.selectByValue("2")", the value is "2" but not the text "2".

In the Selenium version, this code runs fine. What is different about how these tests are run? Note: I have tried to write as much as I can in the format of a question. If you need more information, let me know.

The difference is that in TestComplete, all objects are created at once, before the tests are run. This means that any references you have to elements on the page are stored in a global variable, that is, a property available to all tests.

In Selenium, on the other hand, objects are only created when you are actually running the test. This means that if you have a reference to an element on the page in Selenium, you are only able to reference that object while the test is running. Once you have stopped the test, the object reference is lost.

Is Selenium 4 released?

Selenium 4 was just released last month.

It is still in the development phase. As it is an Alpha release, it is not production ready and it is not recommended for production use. However, if you are using it in your testing tool, you will have to wait until the final release of Selenium 4.

There are several breaking changes between Selenium 3 and Selenium 4. Here's a quick summary of the biggest ones: JavaScript-based tests were removed from Selenium. You will need to use Protractor instead.

Protractor is an AngularJS framework that has similar syntax to Selenium. It is very popular in AngularJS projects.

WebDriver does not need a browser anymore. The test code can now work directly with the web server.

The old Selenium IDE was replaced by the Visual Studio Code extension. The previous WebDriver 2 was replaced by WebDriver 2.53.

Selenium 3 and WebDriver 2 are still supported. Selenium 4 will support WebDriver 2 only.

The new Selenium will support the following features: The Visual Studio Code extension for Selenium. TestNG. Mocha. JUnit. Cucumber. The WebDriver 2 features will be: Asynchronous methods. The ability to specify timeout values. The new Selenium will not support the following features: Selenium RC. Remote WebDriver. The new Selenium supports Protractor. It doesn't support any other languages.

Selenium 4 and Protractor are very similar. They both use the WebDriver library to communicate with the browser. If you're already familiar with Protractor, you should feel right at home with Selenium 4.

One of the best things about Selenium 4 is the JavaScript-based tests. Selenium tests can be written in JavaScript, TypeScript or CoffeeScript.

How many versions of Selenium are there?

Why so many versions?

Selenium is a programming language and I think there can only be 1. So why are there so many versions? What does each version do that previous versions didn't do? There's no definitive answer as to why there are so many different versions of Selenium (and even for that question, there's no definitive answer). The different versions have different programming languages and different levels of functionality. The versions range from web-driver/client-side JavaScript to TestNG/test-level and to C#/server-side.

If you're looking for a definitive list of what each version does, you'll have to contact the developers and ask them. The best place to start is this blog post from 2025 where it briefly explains what each version is and lists the biggest differences between versions.
