Groovy why

And last but not least - Groovy is still one of the most downloaded libraries in the Java ecosystem. Groovy 23M downloads tweet. There are different ways you can get introduced with Groovy. In Spring Boot was released and started gaining a popularity - it also allows you to use Groovy as an alternative for Java. And if you are interested in microservices architectures you might heard about most recent tool in the ecosystem - Micronaut which gains popularity while it is still 1. And if this is not enough, you can use Griffon - a Groovy framework for developing desktop applications.

And not to mention Gradle - this is actually a build tool and not a framework, but its popularity and constant growth keeps Groovy on the radar even though it supports Kotlin DSL as well. This item requires a separate paragraph. Even if you are not interested in any of frameworks mentioned earlier, you might still get in touch with Groovy. Especially declarative pipeline DSL is simplified and opinionated to make pipeline maintainer's life much easier.

It also gives you unlimited options to script your pipeline to do exactly what you want. An obligatory tool in every DevOps toolbox! If I would be limited to pick only a single tool from the Groovy ecosystem, I would pick Spock Framework. No doubts about it. I know many people that do not sympathize with Groovy programming language much, but they really enjoy using Spock as an alternative to good old JUnit in their Java projects.

There is also Geb - a Groovy browser automation solution that makes writing E2E test scenarios as easy as possible. It runs in browser or headless mode, produces test reports in a few useful formats and what is most important - it is very easy to use and write your first browser automation test. Out of the box, there are enough Test Elements to implement almost any test scenario, even a sophisticated one.

However, certain use cases cannot be covered by using default JMeter test elements and functions alone. This leads to the following question: which scripting language to use? Starting from JMeter version 3. This change has a history. Prior to that JMeter users had to download the Groovy library manually and include it in the JMeter classpath.

This caused some problems in using 3rd-party plugins, scaling out JMeter tests when new JMeter instances had to be created on-the-fly and added an extra step when performing an upgrade to a newer JMeter version. Now, all of these problems are gone and Groovy is the only recommended scripting language.

Apache Groovy is a dynamic object-oriented programming language that can be used as a scripting language for the Java platform. The most prominent features are:. If you are using Beanshell, for example, you are limited to Java 5 language level, which means:. MS to jmeter. This is due to Groovy scripting engine size.

As groovy-all As far as you can see, the JSR Sampler calculates and prints the number out in milliseconds, while the Beanshell Sampler needs over 36 seconds to do the same. So if you use scripting for generating the main load or the scripting sampler is called multiple times with multiple threads, the choice is obvious - go for Groovy.

Groovy provides native syntax for some use cases that you might find useful for simplifying everyday life tasks. Assuming you have initialized a File object, you can write to it as simple as this:. I am using groovy in my project. But I dont see much benefit except its dynamic and saves few lines of code. I think if groovy helps more on performance ,then it would be good idea to go for groovy. I was just looking for this information for a while. After 6 hours of continuous Googleing, finally I got it in your website.

Normally the top websites are full of garbage. As discussed by Markus Jais, Now only we are started to work on Groovy, so we feel Java is providing a better readability. Environment Setup 1.

Download JDK Download Tomcat 6. Download Eclipse 4. Then open Eclipse Groovy makes the code very simple and helps quick development. When you use a wrong field in your code, there is an impact from front to back-end and companies will not accept that. So let me get this straight groovy removes type checking so that I can get many more runtime errors and missing property exceptions? I would rather write complete compile time checked code any day.

Code maintenance is one of the biggest expenses in software development, so saving a little time writing code might not really be any savings at all and even a deficit over time.

Thanks for the article. Well, I have used groovy in a project with java for testing purpose for a year now. One thing I can confirm is developers are not interested in groovy. Reason is it is just saving us few line of code but making things complex at large level.

People are habitual to use java and with defined patterns and lot of material on net, it is easy to find solution or standard of doing something which is missing for any dynamic language. It is saving a few lines which can be automated by IDEs but adding complexity for developers, increasing development time, Trends: per trends, groovy or many other languages are nowhere in competition.

January 2nd, It prints the following: the entity with name Giggs is related to Football the entity with name ManchesterUnited is related to Football If you observe there is no compile time check for the presence of the property "name" in the entity. In Groovy you dont need to end statement with semicolon. The same thing in Java will be a bit more effort to code.
