SOAP UI Assertion Help : To validate Total attribute and Total Value - json

Question

I searched in Google and Stackoverflow and I didn't find any helpful information and decide to post question.
I am getting response from API in JSON.
{
"CouponCode": [{
"id": 56,
"name": "BlackFriday"
}, {
"id": 58,
"name": "ThanksGiving"
}, {
"id": 62,
"name": "New Year"
}]}
I need to add assertion that will count that there are total 3 id and 3 name.
All IDs and Names are not empty. We don't want to send empty attribute value.
I am using SOAP UI open source. Please provide exact code or exact reference.
Exactly assertion needs to
Find total Ids and Name that's will be size
Find total Ids and Name size.
If Id is 3 and 3 Ids value are three..if JSON come like in this case assertion will failed.
this
{
"CouponCode": [{
"id": 56,
"name": "BlackFriday"
}, {
"id": 58,
"name": "ThanksGiving"
}, {
"id": "",
"name": "New Year"
}]}

Answer 1

The below groovy script uses json way to check the expected results.
Add the groovy script step after the rest request step in your test case.
Sudo code for extracting the same.
Read the json text. If you do not want to use fixed response, read it from previous step response. Create the object.
Make sure you have the expected counts for id, and name. You may also define them at test case custom properties in case do not want to use fixed values and change each time in the script.
find all the id count and check with expected value and show the error message in case of failure.
Similar to step 3, do the assert for names.
//for testing using fixed response, you may aslo assign dynamic response.
def jsonText = '''
{
"CouponCode": [{
"id": 56,
"name": "BlackFriday"
}, {
"id": 58,
"name": "ThanksGiving"
}, {
"id": 62,
"name": "New Year"
}]}'''
def coupons = new groovy.json.JsonSlurper().parseText(jsonText).CouponCode
//You may also read these values from test case properties
def expectedIdCount = 3
def expectedNameCount = 3
//assert the expected id count with find all coupon ids count of json response
assert expectedIdCount == coupons.findAll{it.id}.size(), "Coupon id count does not match"
//assert the expected name count with find all coupon names count of json response
assert expectedNameCount == coupons.findAll{it.name}.size(), "Coupon name count does not match"
The same can be achieved using script assertion for the rest step as well, that will avoid additional groovy script step. But it may require little changes in the script as below.
How to read the json response dynamically?
From script assertion
Use below line and remove the fixed jsonText from above.
def jsonText = messageExchange.response.responseContent
From Groovy script step
//replace the rest request step name below
def jsonText = context.expand('${ReplaceStepName#Response}')
How to read the test case level properties for expected results instead of hardcoded values in the script?
Define a test case level property for id, say EXPECTED_ID_COUNT and provide value 3 like you mentioned and similarly, define for name as well.
//read in script these properties
def expectedIdCount = context.testCase.getPropertyValue('EXPECTED_ID_COUNT') as Integer

Answer 2

There are several possible solutions. The easiest is to use an XPath assertion; keep in mind that internally, SoapUI converts everything to XML if it can.
count(//*:id)
expected result:
3
Similarly for your name.
