APACHE JMETER PLUGIN HOW TO

This feature lets us synchronize separate Thread Groups. Inter-thread communication means that we can put a string value into a queue from one Thread Group, and then get that value in another Thread Group. Installing the “Inter-Thread Communication” JMeter plugin extends JMeter functionality with an Inter-Thread Communication PostProcessor, Inter-Thread Communication PreProcessor, and a number of functions. It will use the default value (“ERROR”) if the JSONpath (“$.name”) is not found. The extracted value will be saved to a variable (“blazemeterVar”). This extractor works similar to the way the XPath Extractor worked.

How to find: HTTP Request -> Add -> Post Processors -> - JSON Path Extractor The JSON Path Extractor post-processor is designed to extract values from JSON responses using the JSONPath syntax. The JSON response is well formatted and very convenient to read. Run the script again and see the difference. Let’s add the JSON Format Post Processor to this sampler. This wouldn’t be convenient if we had a larger response. I have used a Dummy Sampler to emulate a JSON response from the server.Īs we can see, the JSON response is displayed in a single line. How to find: HTTP Request -> Add -> Post Processors -> - JSON Format Post Processor This post-processor formats JSON responses and makes them more readable. We can see the result of the sampler in the screenshot below. The text entered in the JSON input field will be converted to XML format. How to find: Thread Group-> Add -> Sampler -> - JSON to XML Converter This sampler transforms JSON text into XML format. The Jenkins plugin can be installed via the Plugin Manager as “JSON Plugins”. These elements are a set of tools that enable us to work comfortably with data in JSON format. Installing the JSON Plugins provides us with one more sampler and two post-processors: the JSON to XML Converter sampler, the JSON Format Post Processor and the JSON Path Extractor. How to find: HTTP Request -> Add -> Listener -> - Transactions per Second Also it has two types of graphs: a detailed display (one row per sampler) and an aggregated display (all samplers combined). The Transactions per Second listener shows a graph of the number of successful and failed transactions per second for each sampler during a test run. How to find: HTTP Request -> Add -> Listener -> - Response Times Over Time The Response Times Over Time listener shows a graph of the average response time in milliseconds for each sampler during a test run. How to find: HTTP Request -> Add -> Listener -> - Active Threads Over Time The Active Threads Over Time listener shows a graph of how many concurrent users are active in each thread group during a test run. The plugin can be installed via the Plugins Manager as the “3 Basic Graphs” plugin or as a part of the “jpgc - Standard Set” plugin. These listeners provide you with information and KPIs about your load testing results in a graphic form, enabling you to analyze the success of your performance tests and making it easier to decide on future steps for your website or app. The 3 Basic Graphs plugin extends JMeter with three listeners: Active Threads Over Time, Response Times Over Time, and Transactions per Second. There is also list of available plugins sorted by the number of known users.Īs JMeter plugins are such a powerful tool for building our load tests, let’s take a look at the 10 most popular JMeter plugins and learn how and when to use them. The usage statistics contains some interesting information, like a graph showing the % of known JMeter version installations over time. The website also contains some more useful information such as: guides, descriptions, usage statistics and a support forum. We can search through the 70+ available plugins and hopefully find one that fits our needs. There are a lot of available plugins for JMeter. Developers have already created a large variety of useful plugins, which is really cool and shows the strength of the JMeter community. By default, JMeter has many features, but one of the best things about JMeter is that it is open source software! Therefore, any interested party can develop additions that will extend its capabilities and insert functions.

Apache JMeter™ is a powerful tool for load testing.
