Is JMeter easy? How can I become a JMeter Tester?

Although this cannot be said whether is JMeter easy or tough, as its totally a subjective question. Still here we have tried explaining all about JMeter. JMeter is an open source tool for load testing, which is very famous with enterprise and web-based applications. Load and performance testing are an upcoming field in software testing primarily because of mobile and web. Hence, a lots of job opportunities are coming up in top tier companies such as- TCS, Wipro etc.

What is JMeter?

First designed by Stefano Mazzocchi of the Apache Software Foundation. JMeter is a software that can be used to execute performance testing, load testing and functional testing of your web applications. JMeter can also counterfeit a heavy load on a server by creating tons of virtual concurrent users to web server.

Since JMeter is an open source application. Therefore, this means that you can download JMeter’s source code to analyse and modify it if you want.

Nowadays, JMeter has become one of the most popular testing tools in the world, beside Selenium and Load Runner.

Advantages of using JMeter

Now that you have clearly understood what JMeter is. So, let us look at some of the advantages of using JMeter. As there are tons of testing tools out there such as Load Runner, Selenium, and QTP. Then why do you need JMeter to do the performance testing? This is because JMeter has got features that other tools do not have.

Advantages at a Glance

  • Firstly, open source license: JMeter is totally free, allows developer use the source code for the development
  • Secondly friendly GUI: JMeter is extremely easy to use and doesn’t take time to get familiar with it
  • Thirdly platform independent: JMeter is 100% pure Java desktop application. So it can run on multiple platforms
  • Subsequently full multithreading framework. JMeter allows concurrent and simultaneous sampling of different functions by a separate thread group
  • Next visualize Test Result: Test result can be displayed in a different format such as chart, table, tree and log file
  • Also, easy installation: You just copy and run the *.bat file to run JMeter. No installation needed.
  • Moreover, highly Extensible: You can write your own tests. JMeter also supports visualization plugins allow you to extend your testing
  • Then, multiple testing strategy: JMeter supports many testing strategies such as Load Testing, Distributed Testing, and Functional Testing.
  • In fine, simulation: JMeter can simulate multiple users with concurrent threads, create a heavy load against web application under test
  • Following, support multi-protocol: JMeter does not only support web application testing but also evaluate database server performance. All basic protocols such as HTTP, JDBC, LDAP, SOAP, JMS, and FTP are supported by JMeter
  • Above all, record & Playback – Record the user activity on the browser and simulate them in a web application using JMeter
  • Last but not the least, script Test: JMeter can be integrated with Bean Shell & Selenium for automated testing.

The Skills Required

There are certain skills required to become a JMeter Tester. So, we have discussed them here for you.

Scripting is life

Technical market is flooded with the performance testing tools. All these tools have distinct functionalities and support several development languages. So, this is because why some scripting skills are required in order to build load tests. As on some days you might need to use JMeter where you develop Java or JavaScript. While, another day you might need to use the visual Studio and implement C# codes. Therefore, there are several roads to map when it comes to performance testing.

Basic Understanding of System Architecture

Since performance testing requires you to learn the development languages, libraries and Structures which are utilized in building the software. Therefore, you need to grasp the understanding of functioning of Garbage collection, in case you work with a java or. NET project.

Become a Certified JMeter Tester

As Memory, CPU and network bandwidths might be the root cause of a performance glitch in an application. So, hardware architecture and network layers are components need the analysis during a test.

CSS and XPath Selectors

During a project, most of the time, performance test engineers have to deal with HTTP requests and validate some data in its responses. Therefore, CSS and XPath Selector are used widely, just in order to extract or validate data from a response and build another request. So, in case if they don’t work, regular expressions have to be used to extract data. As test automation engineers already possess the required skills and have the necessary knowledge so they can be considered as candidates to work on a performance test project as.

Understanding the User Behaviour

As we’re very well aware that behaviour of users varies and often turn out to be totally unexpected. This is the reason performance test scripts might be different than the automation scripts. Because they need to reflect the user experience on your software.

Therefore, to understand the user behaviour and scenarios thoroughly one needs to get in touch with and learn more about the business users, people in marketing and product owners. As they will provide with necessary and relevant information about the user behaviour at the peak times, the workload and also the other useful details pieces.

For instance- it’s tough or next to impossible for a single software developer to reflect the behaviour of the user during a Black Friday, so the only thing the developer could help you in gathering is the statistics of the transactions took place.
