Overview of JMeter

How Does Jmeter Works?

JMeter uses the Groovy language as a scripting language. Groovy has shown to be a robust yet lightweight language in terms of performance when it comes to boosting JMeter's capabilities.

Jmeter simulates groups of users sending queries to a server or network and then provides statistics to the user via visual graphs. The user interface of Apache Jmeter resembles that of a browser. Jmeter, however, cannot render hypertext mark-up language pages or the JavaScript within them as a browser would.

Jmeter Environment

JDK installation

Jmeter is a java framework, and the primary requirement is to install JDK in your Windows operating system. You need JDK 1.6 or above version to run the J meter smoothly. Moreover, besides JDK, there is no minimum system requirement to run the J meter.

Setting up the Java Environment

Go to system properties, you can see “Environmental Variables” below.

Set the environment variable JAVA_HOME to point to the location on your computer where Java is installed.

Verify to see if your machine has Java installed. Open a command prompt and run the java commands given below on your Windows computer.

c:\> java -version

You will get an appropriate output if you have Java installed in your system. Else you can download a java development kit.

Downloading Jmeter in Windows.

Download the latest version of Jmeter.
The installation process is relatively easy and straightforward. You can simply extract the compressed file. Now you can copy and paste the extracted file wherever you want.

Types of Testing

As we can see, there are wide varieties of testing types, but the JMeter is specifically used for load and stress testing. JMeter for load testing is an essential tool to determine whether the web application under test can withstand large loads or not. It also helps in analyzing the entire server in case of excessive load.

The process of testing the ability of a computer, network, software, or device to maintain a certain level of functionality under adverse conditions is called stress testing. The method may include quantitative laboratory tests, such as determining the frequency of errors or software failures.

Is JMeter only for Java?

The Apache JMeter, popularly known as the JMeter, is open-source software. The software is a pure Java application developed to load functional test behavior and measure performance.

Is JMeter and Apache JMeter the same?

For Apache JMeter, JMeter Plugins is a separate project. Each plugin has a distinct function that speeds up the creation and execution of the JMeter Test Plan. Through the Plugin Manager, users can install plugins.

Can we write code in JMeter?
