Failing to do that leads to wrong load test. Here, you can see thanks to Function Helper Dialog, its parameters:Īnd how we can use it in a Java Serialization Sampler (that plugin will automagically transform to binary format) to serialize back to XML the Java Object stored under variable “ transactionBO“:Īs with any load test, it is critical to ensure that the response you receive is valid. This plugin offers a function _ulpJavaToXml that allows you to serialize the Java Object again to XML. You are then able to serialize it again to XML using the next function that will translate it to binary format. Once done, you can then easily modify this object with a JSR223 Post Processor and some Groovy code: This Post Processor is applied to the following response (transformed to XML by the plugin thanks to ULP_Java-to-XML renderer in View Results Tree): In the example below, this post processor will transform the binary response to a Java Object, then call getValue() and store the result under “ userData” variable. This processor extracts part of the response object or the full response object and makes it available as a JMeter variable for manipulation by JSR223 Test elements and Groovy. ULP_Response AS JAVA OBJECT PostProcessor :. ![]() You can then extract any data from it using regular JMeter XPath Assertion and selecting “JMeter variable” and setting it to RESPONSE In the example below, this post processor will transform binary response to XML and store it under variable “ RESPONSE“. This processor extracts the object and transforms it to XML for manipulation by JMeter XPath Extractor. To extract data from Binary responses, our plugin offers 2 Extractors: Without our plugin, the responses being binary, this would be impossible. ![]() Once you have recorded, you now need to do correlation which implies: In the example below, we have made numStore, login and accessToken variables that can come from a CSV or from a previous request like for accessToken. Ensure you make a pause of 5 seconds between every step so that all requests are grouped under one Transaction Controller. Now use your application as per your scenario and you will see ULP_JAVA Serialization Sampler with an XML Body automatically being created under Thread Group > Recording Controller.Start recording by clicking on Start button in “HTTP(S) Test Script Recorder” element.In JMeter, select File > Templates… and select Recording then click Create:.Configure your application as per instructions in PDF docs and start it.Plugin will record the queries and automatically transform the binary protocol to a readable XML format that you’ll be able to variabilize, asserts, correlate. Check in JMETER_HOME/bin/jmeter.log that you don’t have any misconfiguration issue.Copy your application jars into a folder we’ll call APPLICATION_JARS and add to user.properties:.where ubik-javaser-plugin.license is the file attached to the trial mail.ULPJAVASERPLUGIN.LICENSEPATH=/ubik-javaser-plugin.license.Edit JMETER_HOME/bin/user.properties and add:.Unzip the UbikLoadPack bundle (download instructions in trial mail) and copy file “lib/ext/ubik-jmeter-javaser-plugin.jar” to JMETER_HOME/lib/ext.Download and unzip Apache JMeter last version (3.2 at time of writing), we’ll call the target folder JMETER_HOME. ![]()
