The JSONPath Existence Match assertion uses a JSONPath expression to select content from the target property and check whether it exists.
The JSONPath expression in this assertion returns a Boolean value. To compare a value with the specific content, use the JSONPath Match assertion.
This assertion applies only to requests and responses, bodies of which contain JSON data.
To learn more about the JSONPath syntax, see JSONPath Reference.
This assertion is available in multiple ReadyAPI applications. Depending on the application, it validates the following data:

|Functional tests||The request or response body.||See Working With Assertions in Functional Tests.|
|Security tests||The response body.||See Security Assertions.|
|Virtual services||The request body.||See Assertions in Virtual Services.|

Setting up properties
In the JSONPath Expression edit box, specify the JSONPath expression to point at the element you want to check for existence, or use the toolbar controls to create the expression automatically.
To use the toolbar controls, run the request you want to validate at least once.
Click to call the Select JSON dialog. Use it to select a node from the last request or response and create a JSON path expression for this node.
In the Expected Result edit box, specify the value you are expecting to get.
Use these commands to visually select the value from the existing request or response:
Option Description Select Content Add a property expansion in the result. Select from Current Get a value from the last response you have received (or the last request the virtual service has received).
To command the assertion to use an asterisk wildcard (
*) for varying parts of the value, select Allow Wildcards.
Note: If you do not select this option, the assertion will fail on dynamic values.
To test your assertion on the last response you have received (or the last request the virtual service has received), click Test.
To avoid typing the desired JSONPath expression manually, click and select the desired JSON element or attribute in the subsequent dialog.
ReadyAPI will form the JSONPath expression that refers the selected item, and will set the result from the last request or response as the expected result.
ASP.NET-based services enclose the JSON response payload into the
droot element for security reasons. By default, ReadyAPI does not strip the
delement out, but there is an option to automatically remove it. If you turn this option on, JSON-related assertions created from the JSON response will not take the root element into account, which can cause the assertion to fail unexpectedly.
