Apache JMeter is a load testing tool that may be used to analyse and measure the performance of a range of services, with a focus on online applications. The Apache JMeter is purely Java open-source software. And this was designed to load test functional behaviour and measure performance. Hence, you can utilize JMeter to analyze and measure the performance of web applications or a variety of services.
Performance Testing literally means testing a web application against a heavy load, several and concurrent user traffic. Though, JMeter originally is used for testing Web Applications or FTP applications. While, nowadays it is used for a functional test, and database server test, etc.
Why JMeter?
We should know why to choose Jmeter. And to understand this better let’s understand through an example. To test your webserver to know how efficient it is? Think of the number of concurrent users a web server can handle? For instance: your senior asks you to start performance testing of some XYZ.com for a minimum of 100 users. Now think what exactly would you do?
It’s clearly not feasible to arrange 100 people with PC and good internet connectivity simultaneously to access XYZ.com. Now think of the framework requirement when you test for 10000 users (which actually is a very small figure for top companies). Therefore, you need a tool like Jmeter that will simulate real-user behaviours and the performance/ load test of your site.
What are the advantages of JMeter?
- The Open source license: JMeter is totally free, therefore, allows the developer to use the source code for the development
- Friendly GUI: JMeter is extremely user-friendly therefore easy to use and doesn’t take time to get familiar with it.
- Platform independent: Since JMeter is 100% pure Java desktop application. Therefore, it can run on multiple platforms
- Full multithreading framework. JMeter allows concurrent and simultaneous sampling of different functions by a separate strand group.
- Visualize Test Result: Test result can be exhibited in a different format such as chart, table, tree and log file
- Easy installation: No installation is required.
- Highly Extensible: You can write your own tests. JMeter also supports visualization plugins, therefore, allowing you to extend your testing
- Multiple testing strategies: JMeter supports many testing strategies such as Load Testing, Distributed Testing, and Functional Testing.
- Simulation: with concurrent strands JMeter can simulate multiple users, thus creating a heavy load against web application under test
- Support multi-protocol: Not just only supports web application testing but also database server performance is evaluated. All basic protocols such as- HTTP, JDBC, LDAP, JMS, FTP, and SOAP are supported by JMeter
- Record & Playback – Records the user activity on the browser and simulate them in a web application using JMeter
- Script Test: for automated testing Jmeter can be integrated with Bean Shell & Selenium.
How does JMeter work?
Let’s take a look at the different steps that JMeter performs during testing:
- Firstly it creates a request and sends it to the server.
- Secondly receives the response from the server, collects them and visualizes those details in a chart or graph.
- Thirdly processes the response from the server.
- Subsequently generates the test result in several formats such as text, XML, JSON so that the tester can analyze data.
Now you know the working of Jmeter, So what all it takes to learn the concepts of Jmeter?
In the current scenario, testing the performance of applications using the JMeter tool has already become a huge field. Therefore Instead of using thousands of people to test the web application manually, performance testers use JMeter to handle different types’ situations on the site. As for performance tester in your career, JMeter not only tests the bugs and errors; also tests the faults in an application, verifies the infrastructure and identifies the defects related to a web application.

About the methodologies
Generally, we tend to follow the most trending testing methodology. And forget to pay importance to verify whether the product meets expected or required performance. But unfortunately, we figure out this pitfall post-delivery of the product. Nowadays performance testing has become an inevitable part especially for web and mobile applications. As the user strength is very huge for each application. Even if it is not something expected all the time. We need a handy tool in order to cope up with such situations of load and that’s where Apache JMeter comes into play.

Put your phone on silent

Like- your resume, your laptop, your portfolio, etc. Forgetting any of such important aspects of your work comes across as very unprofessional.
Stay positive about your current or past employer
Please refrain from indulging in any negative conversation about your former/ current employer. This will make the recruiter envision hiring you and expect that you’ll demonstrate the same sentiment towards their company.
Maintain a good attitude
It is always a good thing to keep aside your bad mood that you may be in that particular moment. Even if you’re very tired, or say upset still keep that aside. This exhibits your ability to compartmentalize your emotions. Thus you can apply such skills in your workplace setup.
