How to use a variable for verification on a GET request?

joshua.wrixon · May 3, 2022, 2:26pm

Hi,

I’m trying to figure out how I can incorporate variables in to my verifications for GET requests. As an example, lets say the below is the hardcoded value of my verification:

WS.verifyElementPropertyValue(response, ‘address.postcode[0]’, ‘DE1 3GL’)

I named the variable ‘postcode’ and have tried doing the following:

WS.verifyElementPropertyValue(response, ‘address.postcode[0]’, ‘${GlobalVariable.Postcode’)

and

WS.verifyElementPropertyValue(response, ‘address.postcode’, ‘${GlobalVariable.Postcode’)

but no joy with either of these. Does anyone know how I would make this work (either using my example as a demo or a different example)?

Thanks

Try this:

WS.verifyElementPropertyValue(response, "address.postcode", 
 "${GlobalVariable.Postcode}")

Or, just…

WS.verifyElementPropertyValue(response, "address.postcode", 
  GlobalVariable.Postcode)

Unfortunately I got no luck with those attempts as well.

I noticed I think I had a missing bracket so tweaked a few things to the below but still no luck:

WS.verifyElementPropertyValue(response, ‘address.postcode’, ‘${GlobalVariable.Postcode}’)

When I use this, I got the following in the verification log:

Unable to verify element property value (Root cause: com.kms.katalon.core.exception.StepFailedException: Expected element property value ‘${GlobalVariable.Postcode}’ is not equal with actual property value ‘BH2 5LT’

I have input the value for the variable as a string of BH2 5LT and in the body, the value is returning as “postcode”: “BH2 5LT” so I’m not sure why it doesn’t think these values meet.

Read my code again. Make yours match mine. Only THEN can you say it doesn’t work.

Also, please post any error logs.

joshua.wrixon · May 5, 2022, 1:52pm

I did try the those but they also didn’t work.

With WS.verifyElementPropertyValue(response, “address.postcode”, “${GlobalVariable.Postcode}”) and WS.verifyElementPropertyValue(response, “address.postcode”,
GlobalVariable.Postcode) I got given the following message:

5: verifyElementPropertyValue(response, “address.postcode”, $GlobalVariable.Postcode)

Reason:
groovy.lang.MissingPropertyException: No such property: Postcode for class: internal.GlobalVariable

Russ_Thomas · May 5, 2022, 1:57pm

What does this do?

println GlobalVariable.Postcode

Add that before your WS calls.

joshua.wrixon · May 5, 2022, 3:35pm

Sorry for the long message but thought I’d add the verification log’s in case that might help.

I tried with both of the below but the same error log still:

println WS.verifyElementPropertyValue(response, “address.postcode”, “${GlobalVariable.Postcode}”)

println WS.verifyElementPropertyValue(response, “address.postcode”, GlobalVariable.Postcode)

The full log is:

I don’t think Katalon likes the way either of those requests are done I’m afraid. When doing it this way:

WS.verifyElementPropertyValue(response, ‘address.postcode’, ‘${GlobalVariable.Postcode}’)

or this way:

println WS.verifyElementPropertyValue(response, ‘address.postcode’, ‘${GlobalVariable.Postcode}’)

then it give the the following log:

No. Type this line EXACTLY above your WS calls.

joshua.wrixon · May 5, 2022, 3:54pm

println GlobalVariable.Postcode

WS.verifyElementPropertyValue(response, “address.postcode”, “${GlobalVariable.Postcode}”)

and

println GlobalVariable.Postcode

WS.verifyElementPropertyValue(response, “address.postcode”, GlobalVariable.Postcode)

Getting the same response:

The println method outputs its result to the console:

joshua.wrixon · May 5, 2022, 4:01pm

It’s not displaying anything in the console.

joshua.wrixon · May 5, 2022, 4:05pm

Just a heads up, I’m leaving for the day and then off until Tuesday, so may be a delay in me responding to anything posted.

Russ_Thomas · May 5, 2022, 4:05pm

Now we’re getting somewhere…

That underline means the variable (property) is undefined. So the error you’re getting is correct.

joshua.wrixon · May 10, 2022, 12:46pm

I believe I have the value defined correctly within my profile. Is there anything that looks like it should be done differently?

kazurayam · May 10, 2022, 1:45pm

You would be able to find a file <projectDir>/Libs/internal/GlobalVariable.groovy. This is the source code of internal.GlobalVariable class generated out of the Project *.glbl file(s). Please open the file with some text editor, and see how it is written.

I guess, you would find there is no Postcode property in the current version of that groovy source code. In other words, the groovy source is NOT in sync with the Profile you set. This is the reason why Postcode is displayed underlined in the code editor. Such discrepancy sometimes occur in Katalon Studio, perhaps due to some bugs of KS.

You need to drop the out-of-sync groovy source code.

How to?

Close the project
By Windows Explorer or shell command line, Delete some folders under the project root folder:
- Libs
- bin
- .cache
Reopen the project

and see how it goes. Hopefully this clean-up will solve your problem.
