    A test case property can be used with JSONPath match assertions and XPath property transfers so JSONPath property transfer should work as well. It seems to be a defect because $ is a special character for JSONPath and property expansion.

     

    Groovy script can be used as a workaround

    (removed single quotes around id in JSONPath for this example)

     

    def sourcename = 'source test step name'
def propname = 'test case property name'
def jsonpath = '$[*][?(@.displayName=="${#TestCase#AccountNumber}")].id'

transfervalue = context.expand("\${${sourcename}#Response#${jsonpath}}")
context.testCase.setPropertyValue(propname, transfervalue)
log.info transfervalue

Hi,

 

I encountered same issue, when using test case property for a JSONPath query. It just stops working (returns nothing). Any ideas for a workaround?

 

For path like this $[*][?(@.displayName==ABCD)]['id'] - property transfer correctly finds the value an puts it to Test Case property, but when I use another test case property instead of explicit string ABCD like this:

 

$[*][?(@.displayName=="${#TestCase#AccountNumber}")]['id']

 

it stops working just returns null.

 

Ivan.

    I thought that double quotes around ReadyAPI parameter name are serving this purpose. Anyways, PaulMS thanks for help, appreciate that.
