Hi Raghav, this is a great introduction to API testing with Katalon.

[@RaghavPal]

Thanks Roopal

Hi Raghav, Thanks for the Introduction session on API Testing with Katalon. You are Amazing

You're welcome Kiran

[@andit6798]

how about api testing on android devices?

[@LorigemiMasters]

Hi Raghav, Just now i ran the below REST service by selecting method as POST without HTTPBody and able to service response as Status : 201 created. Request: reqres.in/api/users?page=2 Response: { "id":"264", "createdAt":"2020-09-28T16:15:18.765Z" } Is this correct -- i think Post method should ask body right ?

[@RaghavPal]

Hi Govind, if you have selected POST method, it should ask for body, Not sure if this works here as this is a dummy api and not actually creating anything on the server. If you want can create your own REST service and check. Watch this - kzbin.info/www/bejne/bafbYYV_rK2JsMk

[@ahmedriyadh4752]

what's the different between this SW and ( postman & soapUI ) ??

[@RaghavPal]

Hi Ahmed, these are diff platforms, Postman and SoapUI are specifically for API, whereas Katalon Studio can handle API, UI, Mobile and Desktop apps

[@ahmedriyadh4752]

Thanks, in fact I’m usually using sopaUI for testing soapaip and postman for testing restfulapi so I just wanted to know if Katalon do the job for me thus by one stone can hit two birds, I mean learning new different testing technology to achieve all my needs.

[@RaghavPal]

You can use SoapUI for both. But pls do a POC (proof of concept) by automating some of your API before switching. And Katalon studio is now a commercial tool

[@raghumesta26]

Thanks Raghav for this session.

Can I start learning from this series today because it says it was 4 years ago ?

Hi Hazem, I will suggest you start from here - kzbin.info/aero/PLhW3qG5bs-L8qJoRNpkQX_NVrHwYjVxe9 And after getting the basics and project setup ready, then go for API testing videos here

Hi Raghav, Thanks for your tutorial, I need help, does this work on the Windows OS?, the URL is also not found on my device

[@RaghavPal]

Elsa Yes, Katalon Studio works on windows

[@vinushavijay2273]

Hi Raghav.. Need some information...!! There are two types of sources available katalon studio (free) & katalon studio enterprise (commercial). I'm looking for open source test automation tools .. As per my test requirements, assuming that katalon studio works in all aspects like integration with jenkins,git & jira and also using same katalon studio ID in both local and remote machines can work. In over all, the concepts you have shared does it work for free without any cost for an individual base tester for whole project ?

[@RaghavPal]

Hi Vinusha, the free ver is now very limited. Check this - kzbin.info/www/bejne/bIDdfa1mrZl4btU

[@LorigemiMasters]

Hi Raghav, I installed Katalon studion Version 7.7.1 free version and i am unable to "Quick start" option. Is there any problem in installation ?

[@RaghavPal]

Hi Govind, there may be some GUI changes in the new ver. But as long as you are able to create and run tests, this should be fine

[@venkatshabarish1784]

Hi Raghav, may I ask the Pre requisite to learn this course? Thanks

[@RaghavPal]

No strict prerequisite, you can get started from scratch Venkat, If you can check the basic API videos from - automationstepbystep.com/

[@adrianvargas8528]

Hello Raghav, I have a quick question, my katalon is not displaying the response on Json, even if I click on JSON (the app is not converting the script from HTML to JSON), how I can convert my response to JSON?

[@RaghavPal]

Hi Adrian, are you using the same api as shown in video. It may be possible that JSON representation is not available for the response.

[@MbikMbik-h1j]

Hi Raghav, thanks for the videos. It is really helpful. I might need some help (i tried to find solutions everywhere but couldn't get the answer). So i have mobile apps and in the landing page there is text "already have an account? Login" and the text "Login" only that clickable. But when i run it is always not working like didn't redirect to login page. How to handle link within the sentence? Thank you

[@RaghavPal]

I will need more details, what tool are you using, what steps did you perform. Is it related to this video or any other lecture

[@Lifeis1bang]

Hi Raghav, I need to create a test suite for API automation in a mobile app project, would you recommend katalon or SoapUI or something else?

[@RaghavPal]

Hi, in case you want to integrate in your existing framework, then you can check for api testing library like RestAssured for Java.

[@chevinpratama3571]

Hallo Mr.Raghav. Do you have a video ,create Token bearer postman with the katalon, I was export data postman to import katalon,but my postman use token and I dont understand token with the katalon. Thank you mr.raghav

[@monisharaji5686]

Hi Raghav sir,Iam mainframe developer i want to change my field ,so my mentor suggested to study katalon .Before studying katalon what i need to study

[@RaghavPal]

Hi Monisha To become an automation tester, there are a few core concepts you should familiarize yourself with, regardless of the specific tool you'll be using. Here are some suggestions for topics to study: Programming fundamentals: Automation testing involves writing code, so you should have a solid understanding of programming concepts like variables, data types, control structures, and functions. Object-oriented programming (OOP): Many automation tools, including Katalon, use object-oriented programming concepts. Familiarize yourself with classes, objects, inheritance, and polymorphism. Web technologies: Since most web applications are tested using automation tools, it's important to have a basic understanding of web technologies like HTML, CSS, and JavaScript. Test automation frameworks: Learn about different test automation frameworks like data-driven, keyword-driven, and behavior-driven frameworks. These frameworks can help you write maintainable and scalable automated tests. Test automation tools: Of course, you'll need to learn how to use a specific automation tool like Katalon. Once you have a solid foundation in programming and automation concepts, you can start learning the tool's features and functionalities. Agile development: Many companies use agile development methodologies, so it's important to understand concepts like sprints, user stories, and acceptance criteria. Testing methodologies: Learn about different testing methodologies like black-box, white-box, and gray-box testing. Understanding these concepts will help you design effective test cases. By studying these concepts, you'll be better equipped to start using Katalon and other automation tools. Good luck with your transition to automation testing!

[@nidaiqbal8949]

Do I have a question that if you have a knowledge of KATALON STUDIO, how to use and testing or enter commands etc in it then it is possible that you can also use selenium IDE? Is katalon studio works as selenium IDE? Inspecting element is also work as same as in selenium IDE?

[@RaghavPal]

Hi Nida, Katalon Studio provides much more features than Katalon IDE. It uses Selenium core libraries and have some built in functions that you can use to setup your complete automation testing project

[@ryanan1233]

Hi Raghav, this is very good intro to API testing. And how about graphql API with katalon studio ? could you please make some tutorial for that.

Hi Raghav what are the advantages of using katalon? Tks

[@RaghavPal]

Hi El, Katalon is a ready framework for UI, API and Mobile testing, You save time in basic setup etc. Plus you do not need programming backgroud to use it

[@elbobs2010]

Hi Raghav, excelent, i'll try to run a POC with Katalon. Thank you!

[@waynejoseph8990]

Thanks for the great tutorial Raghav :) I am using the latest version of Katalon: 6.1.5 I followed the example ok and the ABC Bank response code displayed perfectly fine but the History pane on the right remains stubbornly empty despite the successful execution :-/ Is anybody else having the same problem? Maybe there is a bug in these later versions of Katalon? Or do I have to switch some preference on?

[@waynejoseph8990]

I got some news from the Katalon forum - it is indeed a bug (I am good at my QA job!). "It is a known issue, we will fix it in v6.1.6."

[@RaghavPal]

Glad to know this Wayne, keep finding more bugs

[@waynejoseph8990]

@@RaghavPal Cheers Raghav - I am hoping to minimise the number of QA tools we use so if we can use Katalon for API testing as well, that would be great. Hopefully v6.1.6 will be released soon :)
