Most of these cases were managed by transition from BeanShell to Groovy. This is thanks to Groovy’s compilation capabilities, which enable Groovy to compile the code to bytecode. The bytecode can then be handled more efficiently by the Java Virtual Machine.
What is the main reason to use JSR223 elements with Groovy instead of BeanShell?
2 Answers. Well-behaved JSR223 Sampler with Groovy language and Compilation Cache feature enabled will work faster and have lesser memory footprint than Beanshell. Remember not to reference JMeter Functions or Variables in form of ${var} directly in Groovy script body.
What language is BeanShell?
Java
BeanShell is a small, free, embeddable Java source interpreter with object scripting language features, written in Java.
What is jsr233?
Overview. JSR223 (spec ) is a standard scripting API for Java Virtual Machine (JVM) languages . Currently the following languages are known to work well for openHAB scripting: Jython (Python on the JVM), and Apache Groovy (JVM scripting language).
What would you need to use JSR223 elements with Groovy code?
You can use Groovy in four JMeter elements: JSR223 Sampler, JSR223 Postprocessor, JSR223 Preprocessor and JSR223 Assertion. Besides, you can use small Groovy scripts in any another element using __groovy() JMeter Function.
What is Groovy script used for?
Groovy is a scripting language with Java-like syntax for the Java platform. The Groovy scripting language simplifies the authoring of code by employing dot-separated notation, yet still supporting syntax to manipulate collections, Strings, and JavaBeans.
What is BeanShell used for?
BeanShell is a small, free, embeddable Java source interpreter with object scripting language features, written in Java. BeanShell dynamically executes standard Java syntax and extends it with common scripting conveniences such as loose types, commands, and method closures like those in Perl and JavaScript.
What is BeanShell PreProcessor in JMeter?
BeanShell is one of the most advanced JMeter built-in components. Beanshell PreProcessor – A pre-processor to another sampler that is executed before the sampler and can be used for prerequisite setup (i.e. to generate some input).
What is BeanShell Java?
Is groovy dying?
Groovy will continue to stick around as it’s the dynamic alternative to Java with syntax that is close enough to Java to allow many developers to make the switch (or at least dabble in it).
What’s the difference between Apache Groovy and BeanShell?
Apache Groovy , on the other hand, is a dynamic object-oriented programming language that can be used as a scripting language for the Java platform. Let’s take a deeper look at the main characteristics of each:
What kind of scripting language does BeanShell use?
BeanShell is a small, free, embeddable Java source interpreter with object scripting language features, written in Java. BeanShell dynamically executes standard Java syntax and extends it with common scripting conveniences such as loose types, commands, and method closures like those in Perl and JavaScript.
What are the advantages of using Groovy instead of Java?
Perhaps one of the most important features that we have mentioned about Groovy is the fact that it’s statically compiled, which means that we can obtain top-notch performance, similar to what we would achieve using Java.
