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. If it is ‘True’, then each thread has its own value.In this example, we will demonstrate the use of BeanShell components in Apache JMeter. Per Thread(User): If it is ‘False’, then the generated value will be shared between all threads in the thread group. By providing the seed, you instruct JMeter to generate the random value in the same order in each test. The default is the current time in milliseconds. Seed for random function: The seed for the random number generator. Maximum Value: The maximum value of the random number range. Minimum Value: The minimum value of the random number range. If nothing is specified then randomly generated value will be passed as it is. In the above example if 12345 value is randomly generated then cust12345 will be the string. Output Format: You can specify the format of the string. The value can be called using the same variable name anywhere in the test script. Variable Name: The name of the variable to store the generated random value. Comments: To provide arbitrary comments (if any). “Random Variable” has the following input fields: What are the input fields of ‘Random Variable’? You can follow steps to add Random Variable config element:

Refer to the below screenshot, in which ‘rand_CustomerID’ is a random variable which will store a string value like custXXXXX where XXXXX is any random value between 1 to 99999: Figure 01 How to add ‘Random Variable’ in JMeter? The generated value can be concatenated with a string which is stored in a variable as a string. In JMeter, ‘Random Variable’ config element is used to generate random integer value between a specified range for each iteration.
