Selenium testing software is a leading automation framework for web applications. There are also Selenium alternatives for testing. This guide will cover the various Selenium testing tools that are available — and how to use Selenium.
Looking for answers on how, why, or when to use Selenium for automation? Read along or jump ahead to the section that interests you most:
How Selenium works: The Selenium testing software tool is used to automate tests across browsers for web applications. It’s used to ensure high-quality web applications — whether they are responsive, progressive, or regular.
Selenium is an open-source tool. And, Selenium releases regularly. Testers like using Selenium because it’s easy to generate test scripts to validate functionality. It’s also reliable.

Providing a consistent experience across browsers, devices, and platforms is critical. Each digital experience is a reflection of your brand. And that’s why web testing needs to be an integral part of your test automation strategy.
With so many browsers, operating systems, and devices, you have limitless permutations to test. But with automated web testing with Selenium, you can execute tests quickly to accelerate your DevOps processes.
Selenium testing tools include the following.
Selenium IDE is a free plugin on the browser that helps you record, edit, debug, and replay functional tests.
Selenium WebDriver is a browser-based driver that helps in accessing and launching different browsers.
Test engineers and developers will find many options to leverage Selenium WebDriver technology. A lot of frameworks have been derived from Selenium and extended its capabilities. These include Protractor, WebDriverIO, CodeceptJS, etc.
Selenium Grid has a hub-and-node architecture that helps you do parallel tests across different browsers.
With Selenium testing, you can write test scripts in a number of different languages, like Java, Python, Ruby, C#. The Selenium testing tool automates your tests and runs them against browsers, like the ones Perfecto provides in the cloud.
No, Selenium can not be used for mobile testing directly, but it offers frameworks for testing mobile apps. You can test your web apps on Selendroid, which is a Selenium-based mobile testing framework for Android. For mobile testing there's also Appium, XCUITest, and Espresso.
Whether you are a developer or a test engineer, you are probably doing Selenium testing today. The only difference between them are:
A test engineers would typically feel quite comfortable automating tests with Selenium — and all the other frameworks. But they will find the headless browser testing less relevant to their needs (excluding exceptions).
The software developer will most likely use less of the full-blown Selenium framework. They will benefit from headless browser testing solutions like Google Puppeteer. It all comes down to the quality objectives each persona has.
You may be wondering how well Selenium works. Rest assured, it is the leading testing tool for web apps. Selenium helps you execute automation, so you can test more permutations for fewer escaped defects.
You can create test automation using Selenium frameworks that are low-code or no-code. These allow business testers to put some automation into their day-to-day activities.
Here’s what to consider when learning how to use Selenium.
Cross-browser testing with Selenium is more critical than ever. Using Selenium with Perfecto makes it easier to create cross-browser test automation.
Perfecto removes the entire setup of a local Selenium Grid. You’ll get seamless and secure access to a Selenium grid in the cloud that is elastic — and always on and up to date.
Automating across browsers and real devices in the cloud with Perfecto ensures robust, stable, and highly visible test execution activity.
Codeless Selenium testing is important to improve test coverage. But you’ll need the right tools to support codeless testing with Selenium. You can use Perfecto Scriptless for codeless Selenium testing.
This solution enables a machine-learning capable test automation record and playback on real desktop browsers. It is fully integrated into the Perfecto cloud and smart reporting.
Headless browser testing delivers fast feedback for unit and functional tests to developers. Examples include Google Puppeteer and Mozilla. Headless browser testing improves test coverage — and is easy to set up.
Selenium won’t be your only testing tool. But it is the foundation for many frameworks. For example, Protractor is built on top of Selenium to enable application testing of an AngularJS application.
And Selenium integrates with everything. Here are some areas where you might consider using additional testing tools with Selenium to:
You’ll also want to consider your overall test automation strategy.
If you want to be successful, you’ll need to look at a mix of these frameworks — including cross-browser coding-based frameworks, codeless, and headless.
Some final questions to ask include:
Especially in today’s reality — when you have a responsive web app or progressive web app — you need to answer these questions.
Selenium is the leading testing tool for web apps. But to get the most out of Selenium, you need to use the right testing platform.
That’s why you need to use Selenium with Perfecto.
Jump to 24:48 of the video below to see how to use the Selenium testing tool with Perfecto.
Selenium and Perfecto are seamlessly integrated. Selenium gives you the framework. And Perfecto gives you an enterprise-grade platform with all of the devices and browsers to run your Selenium test scripts on. At the end, you’ll be able to easily analyze the results for fast feedback and prevention of escaped defects.
You’ll get open integrations between Perfecto, Selenium, and other testing tools. Plus, you’ll get faster test execution, maximum test coverage, enterprise-grade security, and advanced reporting and analytics.
