Different Types of Pre Processors in JMeter - ArtOfTesting PreProcessors can be used for different performance testing needs, like fetching data from a database, setting a timeout between sampler execution or before test data . You can follow the below steps: Select the appropriate element where you want to add the preprocessor Test Plan Thread Group Controller Sampler Right-click on the element Hover the mouse on 'Add' Hover the mouse on 'Pre Processors' Click 'JSR223 PreProcessor' What are the input fields of 'JSR223 PreProcessor'? If there are any errors, these will show up in the Tree View and jmeter.log file. Add a Raw Data Source PreProcessor to the thread. The JSR223 preprocessor is used to perform some operation using JSR223 scripting before a sampler request. Jmeter pre and post processors regular expression extractor, JSON PreProcessors are JMeter elements that are used to execute actions before the sampler requests are executed in the test scenario. This also allows a variety of programming languages to be used, including Java, Groovy, BeanShell, JEXL, and so on. Let see this: get ("month") It is not necessary to declare the definition type for the variables. JSR223 Pre-processor performs before the sampler request and runs the operation using the JSR223 script. It required users to create default config elements that would fill in blank values of Samplers. In this blog post, we will use JMeter 3.2 and the JSR223 Sampler element in which Java. Add Sampler "HTTP Request". PreProcessors are JMeter elements that are used to execute actions before the sampler requests are executed in the test scenario . This is the variable that was stored in the Regular Expression Extractor. What is jsr223 postprocessor in jmeter? The name of the created variable will have the extracted text saved. You can attach Pre-Processor with the sampler for which you want to make some changes in the request. Groovy enables you to: Use vars.put (), vars.get () to get and set JMeter variables inside one thread; Use vars.putObject (), vars.getObject () to get and set any objects like lists and maps inside the thread; Use props.put (), props.get () to get and set JMeter variables between threads. ctx vars propsJMeter Context https://jmeter.apache.org/api/org/apache/jmeter/threads/JMeterContext.

For this purpose, you need to add JDBC Connection Configuration element under Test Plan (if you have more than 1 thread and use the same database configuration). The following variables can be used in any JSR223 script: JMeter variables and functions The underlying JMeter will process variables and functions before passing the script field to the interpreter. First, add the JSR223 PreProcessor. To add the BeanShell PreProcessor to Sampler request: Right Click on the Sampler -> Add -> Pre Processors -> JSR223 PreProcessor To show the JSR223 preprocessor in action we can rewrite the previously created script for a random string creation which we used with BeanShell.

Regular Expression Extractor is one of the most helpful JMeter Post-processors in pattern matching. This example demonstrates a simple BeanShell use case with BlazeMeter under the following TestPlan structure: Thread Group (1 user, 1 second ramp-up, forever) While Controller with empty condition (forever) Counter (start - 1, increment - 1, reference name - counter) HTTP request (server name . Step 2 : Save operation.groovy file to the script folder, and should be related to the script .jmx file like: Step 3 : Go back JSR223 Sampler/Post-PreProcessor, and call the script as the way I did in Example 3. We are using it for the matching pattern on contents, values, and expression. The JSR223 postprocessor allows you to use precompiled scripts within test plans.
