Apache jmeter use variables code#

We will sort the content of the array and convert it into string. We will define an array of 5 alphabets (a,b,c,d,e) stored in random order. We will take a simple test case of sorting an array. We will now demonstrate the use of BeanShell in JMeter. It holds the last result from the sampler These are variables loaded as properties from an external file ( jmeter.properties) stored in the classpath. This is a thread local set of variables stored in a map used by BeanShell components in the same thread. It holds context information about the current thread that includes sampler and its results. The following table shows some of the common variables used by the BeanShell components: Variable name Every component provides you with pre-defined variables that can be used in the corresponding script. Data can be passed between these components using thread local variables which has certain meaning and context. For example, it will first invoke PreProcessor then Sampler and then PostProcessor and so on. JMeter will execute the scripts based on the lifecycle order of the components. JMeter provides the following components that can be used to write BeanShell scriptsĮach of these component allows you to write scripts to conduct your test. You can give BeanShell commands interactively in a GUI shell and see the output instantly.įor more details on BeanShell, you can refer to the official website 1.2. BeanShell also provides the concept of UNIX like shell programming. BeanShell scripts can also be written in a standalone mode in a external file which then can be loaded and executed by the Java program. It also supports what is called as scripting variables or loosely typed variables.

The script can also be embedded in the Java code and invoked using the Interpreter API.īeanShell can also be used as a configuration language as it supports creation of Java based variables like strings, arrays, maps, collections and objects. One can use it for quick or rapid prototyping or quickly testing a small functionality or a process. BeanShell aids in quick development and test of Java application. It is an embedded interpretor that recognizes strongly typed Java syntax and scripting features like shell commands, loose types and method closures (functions as objects). It in some way is an extension to the mainstream Java language by providing scripting capabilities.

It enables you to perform testing based on regular expressions and many more other features.īeanShell is a scripting language written in Java.

It gives you real time test results that covers metrics like latency, throughput, response times, active threads etc.

It allows for remote testing by having different JMeter instances running as servers across nodes and accessed from a single client application.

It supports creation of different flavors of test plan that includes Web, Database, FTP, LDAP, Web service, JMS, Monitors etc.

It supports parameterized testing through the concept of variables.

It provides debugging and error monitoring through effective logging.

It enables you to build test plan structurally using powerful features like Thread Group, Controllers, Samplers, Listeners etc.It provides a concept of template which are pre-defined test plans for various schemes or protocols that can be directly used to create your required test plan.JMeter can also be ported on the server allowing to perform tests in a distributed environment. It also allows you to work in a non-GUI mode.

It provides a comprehensive GUI based workbench to play around with tests.It supports wide variety of protocols for conducting tests that includes, HTTP, HTTPS, JDBC, FTP, JMS, LDAP, SOAP etc. It supports testing on both client-server and web model containing static and dynamic resources. The application may be running on a Web server or it could be a standalone in nature. IntroductionĪpache JMeter is an open source Java based tool that enables you to perform functional, load, performance and regression tests on an application. Before we look at the usage of different BeanShell components, let’s look at the concept. These scripts will be part of BeanShell components that we will configure for this example. We will go about writing a simple test case using BeanShell scripting language. In this example, we will demonstrate the use of BeanShell components in Apache JMeter.
