If you are working with modern web stack applications like AngularJS, ReactJS etc, then you need to use JSON processor. JMeter 3.0 has dedicated JSON extractor called JSON Path PostProcessor which is same as Regular Expression Extractor.

For the JSON path expression, please refer http://goessner.net/articles/JsonPath/

Below is the glimpse of XPath and JSONPath syntax.

XPath JSONPath Description
/ $ the root object/element
. @ the current object/element
/ . or [] child operator
.. n/a parent operator
// .. recursive descent. JSONPath borrows this syntax from E4X.
* * wildcard. All objects/elements regardless their names.
@ n/a attribute access. JSON structures don’t have attributes.
[] [] subscript operator. XPath uses it to iterate over element collections and for predicates. In Javascript and JSON it is the native array operator.
| [,] Union operator in XPath results in a combination of node sets. JSONPath allows alternate names or array indices as a set.
n/a [start:end:step] array slice operator borrowed from ES4.
[] ?() applies a filter (script) expression.
n/a () script expression, using the underlying script engine.
() n/a grouping in Xpath

What's new in Apache JMeter 3.0

  1. Hi Naveen,

    Jmeter keeps throwing: java.net.SocketException: Broken pipe
    when I try to send a request to https

    The same request (usecase) works perfectly fine in manual testing.
    Is there any configuration in newer or older version to resolve this and successfully test it using jmeter.
