Hi Raghav, how can I verify element property value for a SOAP test? Do I need to get path for target xml tag?

[@RaghavPal]

Hi, Yes you will need to give the path to get the target element and then validate it

[@vasavip1628]

Thank you for sharing this video

[@whereweregoingwedontneedey4374]

Hi, Question: For the validation of a locator value why use the locator value and not just "Contains String" instead?

[@RaghavPal]

Hi, there are multiple ways we can do it

[@bhargavch6623]

Hi Raghav, thank you for the video..I successfully executed the testcase with one verifyelementpropertyvalue. But how do i verify multiple elements with single testcase. Please advise..thanks

[@RaghavPal]

Hi Bhargav, You will either have to use the keyword for each element, Or you can create a custom keyword for your use. kzbin.info/www/bejne/e5myiKR7qNtsiZI

[@ajeetmalviya7621]

Hi, I have one question, suppose we have 10 test cases and I need to execute them in 5 different ip's(multiple environment). Then how it can be possible to create multiple environment in KATALON.?

[@RaghavPal]

Hi Ajeet, great question, fortunately with Katalon 5.4 ver we can do this using execution profile docs.katalon.com/pages/viewpage.action?pageId=13697476 I will try to do a video on this tomorrow.

How to handle Arraylist in Request body? I have a json request something like { "Data": { "ItemsList": [ "value1", "value2","value3", "value4"], "DateTime":"datetimevalue" } } I am trying to check invalid and empty values in Itemslist array. On using Globalvariable.ItemsList, its printing me [value1, value2,value3,value4] If I pass Globalvariable.ItemsList in the script of SendRequest, i am getting 400 error, invalid request params

[@RaghavPal]

Try to print and check if the data is getting referred properly from Global Variables

[@shanthiva6432]

@ Automation Step by Step: Raghav, can we use Data-Driven for verifying Various Param values. eg : 1) for valid start data 2) valid end date 3) valid start & end date

[@RaghavPal]

HI Shanthi, you can create data as per your need and update the tests accordingly

[@aliahmadfilms8199]

sir i have a question for you i want to get the data from the website and store into the database how can i do it ?? and that would be on regular bases

[@RaghavPal]

Hi Ahmad, for getting data from DB there are in-built features, for storing into db. use DBMS plugin - store.katalon.com/product/24/DBMS-Keywords

[@ronnyhw9682]

Dear sir Raghav, may I ask for the best practice if the data is alot like 200+ data. Do we as a Tester need to create 200 test cases too for ID 1 - 200? thank you very much sir

[@RaghavPal]

Hi Ronny, no, that is the use of data driven that you can use diff sets of data on the same test case, No need to create multiple test cases

[@ErlanggaEr]

Hi Raghav, are you able to open katalon studio with the newest mac os ventura, it keeps crashing on my laptop(8.5.5 katalon)

[@RaghavPal]

Hi, not tried on Ventura, you can let the support team know and can also check on Katalon Forum

[@manoranjanborgohain5412]

Hi Raghav, Thanks for the new API session. How different and benefit it is from rest assured ? expecting a lots from you :-) Request you to cover as a complete demo project including git hub, jenkins integration. Can we integrate extent report api and cucumber here .

[@RaghavPal]

Hi Manoranjan. thanks for watching. While with rest assured you have to add the lib in your project and do all scripting, here the main focus is to make test creation easy and simple. Talking of functionality both are at par. Somebody who does not want to go deeper into coding will like it more. I will do a complete demo project soon.

[@sarangmech]

Very Nice video, well explained tutorial. Do you have any video covering groovy scripting in Katalon Studio to automate api test cases?

[@RaghavPal]

Hi Saranga, I have some videos touching some basics on this. You can find all here - automationstepbystep.com/909-2/online-courses/

[@ShashiBhushankumar-vw9ol]

Hi Raghav regarding the Katalon Studio Version 8.5.5 I am facing one issue after creating the Test case When i adding the Verifying the element Property value when i am adding the Input as a value then Param type is showing Object for me so I am not able to verify the Name because it should be String.

[@RaghavPal]

Hi Shashi, Check the documentation of the keyword docs.katalon.com/docs/author/keywords/keyword-description-in-katalon-studio/web-service-keywords/ws-verify-element-property-value Ensure you are using it as per the syntax You can also try to use different type of verification keyword such as "verifyElementAttribute" you can also try to debug the script and see the actual output of your input variables.

[@ayeshakhanam1973]

I tried to register into an account Gave creds->Clicked on Continue button->It generated a Dynamic 4 digit OTP Switched the tab and opened a url to hit an API which generates the OTP in the below fashion. “CODE-SPLIT”: [ “4”, “7”, “9”, “8” From this Tab2, I need to copy/grab each number every time and switch the tab to Tab1. Paste the copied number i.e., 4 _ _ _ Switch to Tab2 copy/grab the next number i.e., 7 -->Switch to Tab1 paste the number in the 2nd place i.e., 4 7 _ _ Similarly for remaining two ,copy and paste the numbers by switching between the tabs Hurdle is OTP is dynamic. Any suggestions on this issue? Should I store the response some where every time or is there any better approach for this issue.

[@RaghavPal]

Hi Ayesha, If you are getting OTP as an API response, you can store it in a Global variable and then use it in any subsequent request. You will find videos on chaining in this series

So if you got it just once, it might be some issue at server end. You can also check by invoking the endpoint from browser.

[@iridescent10]

Hello Raghav! First of all thank you very much for all the great content you provide on your channel. It's absolutely GOLD! Second, i am totally new with Katalon and also fairly new with automation. I need help with the following: I want to test via API calls an End to End flow. I wish to use the processId from a POST response in another request that needs this processId in the body. The processId is unique and generated for each of the start_process POST request. Is there a possibility to use that id as a variable or something similar, without the use of groovy/java scripts?

[@RaghavPal]

Hi Viorel, yes you can do this, can store the value from a response of a step and then use this in any subsequent step. Check here - docs.katalon.com/display/KD/Handle+Response+Messages

Hi Raghav, How can I generate a random number at the "http body" (POST). The JSON file I'm using at Postman is contain : "identifier": "Eytan{{$randomInt}}" that line gives random number every time I'm sending the API POST request. the problem is that Katalon is no support the " {{$randomInt}}". can you help me generating random number in the HTTP body at Katalon studio? Thank you

[@RaghavPal]

Hi Eitan, if its not already present you can write a custom keyword and call it and use its value.

[@eitannakash]

Hi, thank you for you answer.I don't think i got it. do you mean it the HTTP body field? what keyword would give me random number?

[@RaghavPal]

I meant, you will need to do scripting to create a program to create random integer and make a custom keyword that you can use. You can see this kzbin.info/www/bejne/e5myiKR7qNtsiZI
