Attach JSON Validator tools to your REST Clients to validate that the responses are well-formed. This tool can also validate JSON payloads against the following schema definitions:

  • OpenAPI/Swagger
  • RAML
  • JSON Schema

Adding and Configuring a JSON Validator

  1. Navigate to your test scenario in the left pane and choose a REST Client.
  2. Choose JSON Validator from the ellipses actions menu.
  3. (Optional) Modify the name of the newly-created tool.
  4. Choose the type of JSON validation you want to perform from the Validate drop-down menu.
  5. If you want the tool to validate that responses are well-formed only, click Save to finish configuring the tool. Go to the next step if you want to validate responses against a supported definition. 
  6. Specify the location of the definition file and the service definition message you want to validate. You can also point to an environment variable using the ${variable-name} syntax if a variable has been defined in the suite. The resolved URL will appear if you point to a variable.
  7. Click Save to finish configuring the tool. 

When the client executes, an error will be reported if one or more of the following conditions apply:

  • JSON payload is malformed
  • JSON is not included in the payload 


  • No labels
