JSON JMESPath Assertion

Part of the Assertions category. Also documented in context in the full Component Reference.

This component allows you to perform assertion on JSON documents content using JMESPath. First, it will parse the JSON and fail if the data is not JSON.

Second, it will search for specified path, using JMESPath syntax.

If the path is not found, it will fail.

Third, if JMES path was found in the document, and validation against expected value was requested, it will perform this additional check. If you want to check for nullity, use the Expect null checkbox.

Note that the path cannot be null as the expression JMESPath will not be compiled and an error will occur. Even if you expect an empty or null response, you must put a valid JMESPath expression.
