Katalon Review 2023: The Katalon Platform

What is Katalon Platform?

The Katalon Platform is a comprehensive software quality management platform developed by Katalon, Inc. This modern platform is built on top of the open-source automation frameworks Selenium and Appium, providing automation teams with a powerful and user-friendly automation testing solution for web, API, mobile, and desktop applications, all in one place.



One of the major strengths of the Katalon Platform is that it enables automation teams to create, maintain, and manage test scripts, all in 1 place, without the need for coding. For more experienced users who desire customization, the platform also offers a full-code scripting interface option that supports Groovy (Java).

Katalon Platform offers a record-and-playback feature, allowing testers to auto-capture test objects, properties, and locators for faster test authoring. There is also a built-in artifact architecture that includes templates for test cases, test suites, test objects, and reports. These artifacts can be reused across APIs, web, and mobile platforms, enabling testers to quickly create tests for repetitive scenarios without having to build everything from scratch.

Furthermore, the Katalon Platform has a cloud-based test execution feature that allows testers to run their test scripts in parallel across a wide range of devices and operating systems. 



Finally, after executing automated tests, Katalon Platform provides real-time visibility and actionable insights through detailed test analytics, bringing testers and QA managers the resources they need to make informed decisions.

Katalon Review: Key features

1. All-in-one testing

Katalon Platform allows testing teams to plan, author, execute test scripts, then generate test analytics for more informed decision-making, all in 1 place. Katalon Platform brings value to the entire QA team, through all stages of the testing life cycle, from Planning, Authoring, Organizing, to Executing and Analyzing.


2. Object Spy & Object Repository

With the Katalon Platform’s Object Spy feature, testers can inspect and capture UI elements and their properties in real-time from the application being tested. These elements will then be added to the Object Repository, where testers can easily name and categorize them into folders for later use. 



For example, here we can copy and paste the URL of the AUT and click “Start” to begin capturing. Simply right click on the element and select “Capture Object”. The object will appear in the “Capture Object” dialog box. You can save these objects to the Object Repository.


The Object Repository is essentially a simple and centralized location for storing and managing UI elements and properties captured. These objects can be reused across multiple test cases. What’s even better is that changes made to an object are automatically propagated to all test cases using that object, ensuring consistency and reducing maintenance effort.


3. AI-augmented automation testing

Katalon Platform AI/ML to dynamically update the test scripts when changes are made to the application. If Katalon fails to find an object with its default locator, it will try other pre-configured locators associated with that object. 

Another AI-based feature of Katalon Platform is the Smart Wait feature, which can determine the optimal time to wait for a web application to respond before executing the next step in the test script. This feature helps testers create stable and reliable test scripts that can handle network delays and other performance issues. 


4. Record-and-playback

This feature enables users to create automated test cases by recording their interactions with the application and generating corresponding test scripts based on those interactions. It simplifies and speeds up the process of creating automated tests as no coding is needed. 

In this example, the action of logging into a website, login in, and making an appointment is recorded. Advanced testers who want to manually input the selectors have the option to choose between CSS and XPath modes.

However, as the product matures and its community grows, more support will become available. There is the Customer Support team at Katalon ready to answer any questions you have. If you need to know more about any specific features of Katalon, you can always find tutorials on YouTube.


Katalon vs Selenium

Katalon and Selenium are both incredibly popular in the automation testing world, offering robust features serving testers of varying needs. There are still some key differences between Katalon Platform and Selenium that you need to consider:

1. Ease of use

Katalon Platform already has everything that you need. It is designed to be user-friendly and offers a low-code approach to test automation, making it easy for testers with little to no coding experience to create and run automated tests. Experienced users can totally switch to coding mode to write scripts themselves on Katalon Platform.

On the other hand, Selenium requires a higher level of technical proficiency and coding skills to utilize all of its power. You have to create all of the testing frameworks from scratch if you choose Selenium, which takes tons of time and effort. However, being an open-source solution, Selenium has a large community of users worldwide contributing resources, documentation, forums, making the learning curve flatter.


2. Test artifact management

Katalon provides an all-in-one solution that includes test artifact management with its Object Repository, whereas Selenium does not offer such a feature, which can make your testing activities messy and disorganized when your application scales and your number of test artifacts grow. 

Moreover, since applications change over time, automation test scripts and objects must be constantly updated to keep up with the adjustment. Without proper test artifact management, organizations may face significant maintenance overhead. 

3. Scripting languages

Katalon supports only Java and Groovy scripting languages, while Selenium supports a wide range of languages such as Java, C#, Python, Ruby, and others. Being an open-source framework, Selenium gives testers the option to select their preferred language to write test scripts.

4. Licensing

Katalon offers a free version as well as paid enterprise editions, while Selenium is an open-source tool that is completely free to use. Therefore, Selenium is accessible to anyone, and you can further extend Selenium’s capabilities through Selenium’s plugins. Katalon Platform, on the other hand, requires initial investment, but QA teams can get started quickly with tons of built-in features.

Ultimately, the choice between Katalon and Selenium depends on your specific testing needs and the technical proficiency of your team. Katalon offers an all-in-one solution that is easy to use and offers test case management, while Selenium is a more flexible and powerful tool that requires more technical knowledge to use effectively.




In conclusion, Katalon Platform is a comprehensive test automation tool that offers a wide range of features and functionalities for automated testing.
