Migrating from Selenium to Katalon | Enable Codeless Test Automation

In the test automation tool market, Selenium is most likely to be the first tool of choice for testers. Selenium is useful for writing test scripts for web applications. It is capable of simple tasks—like checking how the page loads, to a more complex process—like imitating the entire user experience on a website.

Over the years, Selenium has evolved from more than just an automation tool to a much-needed testing skill for QA professionals. However, under the rising wave of Agile & Scrum trends, teams are expected to be capable of rapid releases with high-quality outputs, with the help of automation tools.

As the market requires tools that are more agile and comprehensive, it has revealed the disadvantages of Selenium and its limitations in enhancing growth for teams. To successfully automate with Selenium, it takes significant effort, resources, and the right people for the challenging task.

Selenium In the Current Software Testing Landscape

Selenium is open-source, and the most popular name among its set of tools is the Selenium WebDriver framework. Selenium users can choose to develop their test projects in a host of different programming languages, including Java, C#, Python, and more.

As the pioneer testing tool, Selenium is the foundation for many test frameworks in the market. Selenium’s suite of tools includes Selenium IDE, Selenium Grid, Selenium WebDriver, and Selenium Client API. This suite provides enough flexibility for its users to perform testing on different levels and for many business purposes. Thus the testing community’s interest for Selenium has increased gradually ever since its release.

The Limitations of Testing with Selenium

Limited testing environment

Although Selenium is a powerful automation tool with all the essential features for web app testing, note that its sole focus is web testing. If your team needs to test many different environments, either mobile or desktop application testing, you will have to find an entirely new solution to meet your new testing requirements, with extra time and effort spent along the way.

Testers and QA teams are under the shift towards the “Quality at Speed” trend, so that they can be more adaptive with Agile development. That means the more comprehensive with less redundant setup and configure the tool is, the faster the team can move forward with testing.

Advanced programming capabilities required

Selenium covers almost all browsers with a driver for each, but they require manual configuration. The Selenese test scripts can be used on different operating systems, such as Microsoft Windows, Apple OS, and Linux.

It depends entirely on you and your team’s capabilities to build up, customize, and maintain your own Selenium projects. That’s why it can be a real challenge to ensure it fits into the product development and the existing environment.

Lack of dedicated support for users

As Selenium is open source, there’s no need for license subscription nor user registration. Likewise, being open-source also means there is no reliable support from the tool’s developers. The Selenium community depends entirely on each other, and on the online forums to solve issues, get usage guidance, or utilization consultation.

Lack of native AI and image-based testing capabilities

Today, testing has evolved further away from simply testing based on web elements. As user behavior becomes more complicated over time, more complex test elements like image testing, integration with AI/ML technologies, and scalability capabilities are becoming more critical to ensure product quality.

Selenium users need a third-party tool to enable comprehensive image-based testing or get equipped with AI testing technologies.

It’s Time to Switch Your Selenium Tests to Katalon Studio

Undoubtedly, Selenium is one of the most popular tools for automation testing. However, Selenium’s integration limitations and advanced programming skills requirements are major development setbacks for scaling teams, and the Katalon team deeply understands this struggle.

Built on top of Selenium and Appium, Katalon Studio is seen as the best alternative solution to Selenium over recent years. From version 7.4.0, you are able to migrate your Selenium tests in TestNG/JUnit framework to Katalon Studio, without having to rewrite the test cases from scratch. Take a look at the reasons below to understand why Katalon Studio can help people overcome Selenium’s obstacles.

A codeless tool for all platforms and OSs

Katalon Studio requires little to no upfront environment or server setup to begin automating test projects. It provides built-in project templates, test case libraries, keywords, and object repositories to best simplify the learning curve for new users and help them accelerate quickly with test automation.

Katalon Studio users can confidently apply end-to-end testing on all web, mobile, API, and desktop testing in a single project. Similarly to Selenium, Katalon supports testing on Windows, macOS, and Linux. However, Katalon users can scale more with built-in custom keywords, advanced debugger, auto-healing, and auto-waiting capabilities.

Testers don’t have to have advanced programming skills to get used to the testing functionality of Katalon Studio. The tool makes it easy for them to combine different testing platforms, scale up the project, and integrate with even more tools. It is capable of not only codeless testing but also has support for advanced extensions for automation experts.

CI/CD enabled, testing on the cloud made easy

Katalon offers native integrations with some of the most common CI/CD tools for the testing community. It provides all critical features for businesses to apply continuous testing and streamline the product development cycle. Whereas with Selenium, it is a challenge to maintain a pipeline of concurrent tests and running them on the cloud.

Katalon Studio is a relatively new tool that was built on top of the Selenium framework. It is made to solve and simplify the way integrated automation is delivered for testers. The tool provides native integration capabilities that meet all test requirements from teams.

In terms of CI/CD integrations, some of Katalon Studio’s most notable native integrations are: Jenkins, Bamboo, CircleCI, Azure DevOps, and many more. Users can extend their projects even more with integrations for execution platforms, such as SauceLabs, LambdaTest, Kobiton, and BrowserStack.

Proven ROI for teams at any stage

Made with the user’s adaptability on top of mind, the Katalon team provides all the crucial features to ensure collaboration for team members while enhancing their ability to manage projects as well as keeping track of executions.

Katalon empowers DevOps for Agile teams with its TestOps. By integrating Katalon Studio with TestOps, users can get a holistic view from the start to the end of the project.

Some key features of Katalon TestOps are centralized data and reports, test execution planning, and pipeline optimization.

How to Migrate Selenium Tests to Katalon Studio

Migrating from Selenium to Katalon is done with ease. The Katalon team wants to make sure that teams can maintain their existing Selenium test scripts while getting the comprehensive features of Katalon Studio.

With the latest Katalon Studio version update, empowering your Selenium tests with codeless capabilities is just a few simple steps away:

• Step 1: Choose the Selenium project you would like to migrate.  
  Note: You may need to add Java dependencies of your project to .gradle file. Learn more
