JsonPath assertion

[Daniel-ltw]

Current jmeter does json assertion

            <JSONPathAssertion guiclass="JSONPathAssertionGui" testclass="JSONPathAssertion" testname="JSON result Assertion" enabled="true">
              <stringProp name="JSON_PATH">$.result</stringProp>
              <stringProp name="EXPECTED_VALUE">Energy</stringProp>
              <boolProp name="JSONVALIDATION">true</boolProp>
              <boolProp name="EXPECT_NULL">false</boolProp>
              <boolProp name="INVERT">false</boolProp>
              <boolProp name="ISREGEX">true</boolProp>
            </JSONPathAssertion>

This gem seems to be using a different java library.

You should be able to do this

module RubyJmeter
  class DSL
    def json_path_assertion(params={}, &block)
      node = RubyJmeter::JSONPathAssertion.new(params)
      attach_node(node, &block)
    end
  end

  class JSONPathAssertion
    attr_accessor :doc
    include Helper

    def initialize(params={})
      testname = params.kind_of?(Array) ? 'JSONPathAssertion' : (params[:name] || 'JSONPathAssertion')
      @doc = Nokogiri::XML(<<-EOS.strip_heredoc)
      <JSONPathAssertion guiclass="JSONPathAssertionGui" testclass="JSONPathAssertion" testname="#{testname}" enabled="true">
      <stringProp name="JSON_PATH">$</stringProp>
      <stringProp name="EXPECTED_VALUE"></stringProp>
      <boolProp name="JSONVALIDATION">true</boolProp>
      <boolProp name="EXPECT_NULL">false</boolProp>
      <boolProp name="INVERT">false</boolProp>
      <boolProp name="ISREGEX">true</boolProp>
    </JSONPathAssertion>)
      EOS
      update params
      update_at_xpath params if params.is_a?(Hash) && params[:update_at_xpath]
    end
  end
end

Users should be able to use this with:

json_path_assertion JSON_PATH: '$.result[6]', EXPECTED_VALUE: 'Energy'
