Katalon Studio

Studio

Studio Enterprise

Runtime Engine

The browser/desktop recording helps to automatically record scripts and helps a lot in saving time to create automation scripts, plus it helps in parallel execution to save time.

QA Analyst

The only con with the software is resolving issues sometimes requires a developer to help fix the test case.

You could also manually write the test scenarios, step by step.  

Test Automation Lead

Integration with Jenkins and support for CI CD

My overall experience is that I could easily begin using the software without training (as a non-developer).  

It can't handle the load of a large number of test cases under one suite and consumes a lot of time.

QA Manager

the only drawback with this software is that it takes one min to execute one step via recording scripts and if device gets disconnected it crashes the whole script

Lots of external tools, libraries, and files are needed to add every functions/features. But In  Katalon , most of the features are built in which made the tool almost CODELESS and less tedious

QA Team Leader

it is codeless orientes, that means new or non-technical users could find Katalon a good option to adopt in the test automation world, Its fully of features, it is being updated and fixed everymonth which mean that the Katalon team is working hard on this tools to improve it on each release.

Director of Technology

Initially it was primarily used for automated monitoring of multiple Single Sign On solutions - allowing us to setup a batch run that hourly would sign in to our various client sites and insure successful sign in and log out through the sites.  

Earlier we used to maintain a Java-Selenium-based Hybrid framework, which required good programming knowledge.

Tester

It's very useful tool for automation developers , Have lot of predefined functions it's making easy work and time saving ,compare to other tools while designing script we can save time up to 60%.

Software Test Engineer

You can easily refactor variables and shared code in Eclipse, but that seems to be a thing that is missing in Katalon. When it comes to updating test case names or the web objects, those get updated across the board enough, but not when it comes to passing variables and keywords around.

Senior Technical Consultant 

In the past 2 years experiencing Katalon Studio, Our test cases based on web application were easily managed, automated and matained by the team, even without technical skills required.

Lawyer 

The only scripting language katalon knows is groovy which is not appropriate for their brand.

Team Lead

UI supports with all browsers option is good.

Senior Automation test engineer

it won't handle drag and drop Functionality efficiently and upload image functionality also not good and select value from drop down also not handled properly

Product Management Analyst

Katalon doesn't shew what's the error directly on the output window, I have to scroll lot to find the error description in console.

Software tester

It provides you in built functionality to select the xpath of objects which is known as self healing.

By that I mean figuring out how you want to model your tests and test objects, whether it's UI, API, or a hybrid.

Qa engineer

Great coding language to pick up and use for regression testing

Test Analyst

The free version also offers enough functionality to users that are in small organisations and can't afford the more expensive tools.

iOS Engineer

Its object spy is a little laggy while using complex iOS applications. But based on its functionality, the lag can be acceptable.

it provides you nice reporting format and also you can configure it with jenkins which made my life very easy.

API execution is also very good and easy to implement for functional Testers.

I've experience working on iOS automation testing using the Xcode tools, but I felt Katalon is the best tool for automation.

Updating doesn't always work (I use a Mac). When I start executing tests, there's usually a delay/lag when things actually start or report.

Don't worry about setting up browsers, updating drivers, only select the browser you want to lunch.

the only drawback which I have seen so far is that, its kind of slow in performance if your project size is very big.

Game Developer

It also has a well-documented API that allows you to extend its functionality.

Senior Test Analyst

I have faced some issue on sometime, like not able to call the method from keyword to test case.

software engineer

Pretty easy to install and configure so junior team can easily install and create automation for your service (web,api, and mobile).

QA engineer

I’ll admin I am kind of a Katalon fanboy, for my needs and workflow Katalon is an amazing tool which enables me to think and develop testing scenarios really fast and almost no friction when adoption the tool for the team.

Senior Software Engineer (Testing)

Readability of Element Property and Execution is Very slow and breaks application.

IT helpdesk Associate 

Some features requires alot of understanding to use like implementing data source feature.

Test Manager

A tool filled with many features for web and mobile applications testing, with an easy-to-learn user interface.

Sr Test Analyst

Support multiple platforms(WEB UI, Mobile, API)

Some part is not able to record and even in coding feeling very difficult

QA tester

Its speed on automaton .xpath several option fast in execution and lot more

Katalon Studio is very good for automation testers and it develops a better-inbuilt framework

We have also used for automated testing of API development.

Need performance testing tools or integration with Jmeter

QA analist

The easy set-up was great, also the scripting allows more flexibility in comparison with other reviewed tools.

Software Tester

Katalon is a good tool to create and store your automated test.

Programmer

Ability to integrate Katalon studio with the the latest automation tools such as Appium, Selenium and Win AppDriver

Test Architect

Getting web drivers updated in a single click is also a simple one.

This is very much useful to test integration of multiple components/systems.

same  issue goes for browser and other Desktop application.

QA Engineer

Katalon is a free tool that can be used in automation. Although it is free, its features are very useful and essential and this is very easy to learn and explore as well.
