verifyElementPropertyValue() always returns Null Pointer exception

Shivraj_Tapkir · November 26, 2018, 2:51pm

I have been trying to verify the element property, but the code always runs into an error. Please find the details below :

Code :

response = WS.sendRequest(findTestObject(‘POST/PostRequest’))

println(response.getResponseText())

WS.verifyResponseStatusCode(response, 200)

WS.verifyElementPropertyValue(response, ‘ctx.dev’, ‘wscott’)

Response:

{

“text”: "

Basically,testing to make sure that individuals have access to all: Hardware, Software, Web pages, Web applications and tools. ",

“ctx”: {

“id”: “37fe”,

“system”: {

“initialized”: true,

“dialog_turn_counter”: 1,

“dialog_request_counter”: 1,

“branch_exited”: true,

“branch_exited_reason”: “completed”

},

“dev”: “wscott”,

“voice”: true,

“example”: null

},

“info”: true,

“paraphraseFlag”: false,

“disAffirmFlag”: false,

“status”: “ok”

}

Error :
Test Cases/POST/TC_01_VerifyResponse FAILED because (of) Unable to verify element property value (Root cause: java.lang.NullPointerException)

In the response, I could see you have ‘ctx’ and ‘dev’ property, but you do not have ‘ctx.dev’ property.

You have now:

WS.verifyElementPropertyValue(response, 'ctx.dev', 'wscott')

Possibly you should change it to:

WS.verifyElementPropertyValue(response, 'dev', 'wscott')

“ctx”:
{

  "id": "37fe",

  "system": {"initialized": true,"dialog\_turn\_counter": 1,"dialog\_request\_counter": 1,"branch\_exited": true,"branch\_exited_reason": "completed"},


 "dev": "wscott",

 "voice": true,

 "example": null

}

‘dev’ is element of ‘ctx’ and therefore i have used ‘ctx.dev’.

kazurayam · November 27, 2018, 11:38am

Ah, yes. Now I see you have ‘ctx.dev’

Hi try below code, I think It will work

response = WS.sendRequest(findTestObject(’‘POST/PostRequest’))

WS.verifyResponseStatusCode(response, 200)

WS.verifyElementPropertyValue(response, ‘ctx.dev’, ‘wscott’)

def slurper = new groovy.json.JsonSlurper()

def result = slurper.parseText(response.getResponseBodyContent())

def dev= result.dev

println(dev)

Shivraj,

Is it possible for you to share the URL of your Application Under Test and you Test Object ‘POST/PostRequest’ detail? so that I can reproduce your problem on my side.

def dev= result.dev

println(dev)

Updated code:

slurper = new groovy.json.JsonSlurper()

result = slurper.parseText(response.getResponseBodyContent())

ctx= result.ctx

dev = ctx.dev

println(dev) //It Prints wscott on the console.

But when I try to verify element property using the below command :

WS.verifyElementPropertyValue(response, ‘dev’, ‘wscott’) or
WS.verifyElementPropertyValue(response, dev, ‘wscott’)

It again gives me a null pointer exception.

kazurayam · November 30, 2018, 8:10am

Please try:

WS.verifyElementPropertyValue(response, 'ctx.dev', 'wscott')

It doesn’t work either. Pasting the console log :

Please insert the following line into your test case and tell me what you get:
