REST Assured: Groovy's GPATH vs JayWay's JSONPath

Groovy's Gpath

  • Apache Groovy is a powerful, optionally typed dynamic language with a multi-faceted java platform. 
  • Groovy comes as integrated support for converting between groovy objects and JSON. 
  • JSON serialization classes and parsing come under this groovy.json package.
  • By default, rest assured, used groovy's gpath syntax.

The GPath is a path expression language integrated into the groovy language. It has similar scope that of Xpath and XML. It used dot-object notation to perform object navigation in JSON. 


  • x.y.z -> For XML yields all the z elements inside x and y.
  • x.y.z -> In POJO yields z properties for all y properties of x.

Jayway's JSONPath

  • Unlike gpath, this one is not directly workable rest assured as we need to add this below dependency in the maven repo.
  • The expression in JSON path is different from gpath in that it solely refers to the JSON structure in the same way of XPath.
  • The root member object in the JSON path is referred to as $ regardless of whether it is an array or an object.
  • We have to add a separate dependency and use it in java programming.

It is pretty popular with java and widely used and expressed in dot notation navigation.


Or it can be notated in brackets too.


Groovy used gpath expressions in the syntax, but here JSON path uses operators.


  • It is essential to know about these differences.
  • Depending on our choice, we can use the proper JSON implementation.
  • Groovy's gpath is available as default syntax in rest assured.
  • Jayway's JSON path is used by adding its dependency.
