I am unable to POST the request for the API. Any thoughts, how can this be solved please ?

Here is the script -
import static com.kms.katalon.core.checkpoint.CheckpointFactory.findCheckpoint
import static com.kms.katalon.core.testcase.TestCaseFactory.findTestCase
import static com.kms.katalon.core.testdata.TestDataFactory.findTestData
import static com.kms.katalon.core.testobject.ObjectRepository.findTestObject

import com.kms.katalon.core.model.FailureHandling as FailureHandling
import com.kms.katalon.core.testcase.TestCase as TestCase

import com.kms.katalon.core.webui.keyword.WebUiBuiltInKeywords as WebUI
import internal.GlobalVariable as GlobalVariable
import com.kms.katalon.core.testcase.TestCase
import com.kms.katalon.core.testobject.TestObject

“Send the POST Request”
response = WS.sendRequest(findTestObject(‘Object Repository/POST’, [(‘url’) : url]))

“Capture the response code and verify”
println response.getResponseText()
println response.getHeaderFields()
println response.getResponseBodySize()
println response.getStatusCode()
WS.verifyResponseStatusCode(response, 200)
WS.verifyElementPropertyValue(response, “status”, 200)
WS.verifyElementPropertyValue(response, “url”, “google.com”)
WS.verifyElementPropertyValue(response, ‘queries.getinfo.cats[0].catid’, 50)

Here is the error -

@spullabhotla, have you tried sending the request with the url defined explicitly, not via variable? Does the error still occur in that case?

3

Yes, the manual way of sending the request works good. I do not see any problem with it. However, parameterize it, the request send breaks.

4

@spullabhotla, can you send us your request object file, so that we have more clues to investigate the issue and help you better?

5

@huynguyen - are you asking about the .rs file ?

6

Yes, @spullabhotla

7

I am unable to attach the file. Seems to be the attachments only accept the picture/graphic files. So I have tried changing it to .png but because of the size is too large for it to attach, the attachments option rejected it.

Any thoughts, how should I share it ?

8

@spullabhotla, can you zip the file and attach it? We have already supported attaching zip file.

9

Please find the zip. It was zipped using 7Zip. If the unzip doesn’t work, please change the extension to 7z.

Appreciate your help.

10

Thanks, @spullabhotla. We will investigate the issue and get you noticed ASAP.

11

Thank you Huy. Appreciate your time.

12

@huynguyen Any update on this, please ?

13

@spullabhotla, you can put your url variable definition in quotes, i.e “urls”: [${url}] to “urls”: ["${url}"]. This is because the quotation marks for string value will not be included on variable value substitution.

14

@huynguyen - thank you very much. It worked. I was able to successfully post the request. Now, I will start the data driven test to work on it with some data. Our aim to rum some data starting with 100s, then thousands, hundred thousands and millions. I hope the tool will definitely withstand the loads of data provided in CSV file.
I will give it a shot and let you know.

15

Thank you and sorry, I had to delete the .rs attachment for security purposes. Appreciate your help.

@spullabhotla @huynguyen
How did it worked for you?
I am facing a similar challenge.

  1. I have a RestAPI which has a numeric ID in it
  2. I want to run the request in loop for multiple IDs, importing data from excel
  3. I am able to import the data from excel but for some reasons the request URL is not accepting the ID from excel file, thereby giving a bad response in return

Here is my code for the process, any help will be appreciated

TestData data = findTestData('BookIDs/book_ids')
for (int j = 1; j <= 21; j++) {
String value = data.getValue(1, j)
def response = WS.sendRequest(findTestObject('JG_APIs/BookDetails', [('BookID') : value]))

WS.verifyResponseStatusCode(response, 200,FailureHandling.CONTINUE_ON_FAILURE)

println(value)

}’

The println is used to verify if i am fetching correct data from excel and as I checked in Console, it was correct.

@Bal_Mukund,
Can you send us your request file (.rs file) together with the data file? We will have more clues to investigate the issue and help you better.

19

@huynguyen Yes, here is the URL, includes the data file and rs file.

20

@Bal_Mukund
Mine was an easy fix. I have changed from “urls”: [${url}] to “urls”: [“${url}”] and it worked like charm.
huynguyen helped me with that and I truly appreciate his help. Our team is very happy to learn it and implement it.

21

Thank @Bal_Mukund,
I have investigated your issue and found out that there are empty spaces in the request params of your URL. This is undesired result as Katalon is expected to handle escaping these spaces automatically. We will improve on this. In the mean time, please try removing these spaces and test again.
