JMeter is very easy to learn. Tutorials from Blazemeter are definitely good for a starter. That is where I started :-) Blazemeter's tutorials have good content and information. Continuous hands-on will help you learn effectively.
For Basic Performance Testing using Jmeter you don't need to learn any programming language. But in some special cases you need to extract a value from the the response, update it and store into a variable. Now that update part is achieved by interference of scripting language. For example, Beanshell Post Processor.
It depends on what exactly you want to do with JMeter and to what extent is your requirement has to be fulfilled.
To be clear , it is an open source tool developed using Java. When you are using JMeter, just think of it is an tool used to test the Web API (similar to Postman).
At an initial stage, use it as just software tool; following Jmeter official documentation is more than enough, it covers most of the web API testing topics.
At this stage you don’t require any programming knowledge, but indeed you should know the basic fundamentals of programming terms (like variables, conditions, loops and regular expressions), not in depth. Just having general idea will help you understand faster and also helps in Beanshell programming (which is embedded in JMeter).
Our courseware is designed to give a hands-on approach to the students in JMeter. The course is made up of theoretical classes that teach the basics of each module followed by high-intensity practical sessions reflecting the current challenges and needs of the industry that will demand the students’ time and commitment.
Groovy has become the recommended scripting language for JMeter because it's easy to use, it is flexible and it is constantly being developed. In addition, Groovy can be fully integrated with Java, which provides many scripting capabilities via an expressive, concise and readable syntax.
Overall Jmeter is a good testing tool and various software testing services companies used JMeter for performance testing. JMeter is built to support performance testing (Load and Stress testing). So Just Enquiry it ! entroll it!.
Any company which hires a software JMeter wants at least a good knowledge of scripting. Performance testing offers a wide variety of career path.To to be a software performance tester so you need some technical skills as well that give you a good job with handsome salary.
Advantages of JMeter
In today’s world where people remain online more often than not, the website and other online assets heavily influence the success and acceptance of enterprises.Companies need to go all out to ensure that their online assets run optimally.
Web administrators run a whole gamut of performance and functional tests to ensure that the websites perform optimally. While there are extensive testing tools for such tasks, many of them are too complex.
Apache JMeter open source software fills a big void in this space by making such tests easy. Though the tests possible with JMeter may still be done manually or with other tools, there are several advantages in using JMeter.
Comprehensive Tool – One Tool Fits All Purpose
- The biggest advantage of using Apache JMeter is the facility of undertaking both performance and functional testing of any required online asset – be it web service, database, FTP or web server, using a single tool. JMeter may also be deployed to test applications that run in the cloud.
- JMeter’s core function is to facilitate load testing of web applications.
- It generates dumb-load of varying quantity and measures the server response times during such loads.
- The response times of various components of a web application usually increases corresponding to increase in load on the server, and there are chances that such increased response times may affect the render time of the web application adversely.
- For instance, a web application heavy with Ajax requests, when put under load, may encounter increased server response times, causing all Ajax-requests to become slower, and in the process offer a harrowing experience for en d-users. The tests conducted using JMeter makes such glitches explicit, allowing web adminis
- trators to take remedial action so that the site does not slow down and offer a bad experience for end users.
- JMeter has of late expanded in scope to incorporate other test functions beyond load testing.
- The tool now hits functional application layers, finding use to undertake functional and performance tests on both static and dynamic resources, including files, Perl scripts, servlets, databases, Queries, Java Objects, FTP Servers and more.
- Web administrators may now use this tool to manage the performance of their websites easily. JMeter combined with Selenium offers an even comprehensive range of functional tests.
- JMeter now finds use in running automated functional tests in a big way. It facilitates the use of automated regression test while the servers are under increased load, to test the entire range of functionality offered by the website or application thoroughly. Performance testing, when the server is under heavy load and when the business logic of the application works hard to handle all requests effectively is extremely important to detect whether the application behaves out-of-norm when put under stress.
- Such extensive testing will make explicit important dimensions such as what happens when the database, equally stressed due to increased load and responding slower than normal, returns incomplete data, or worse, when the application faces a time-out on data or application-logic. It also makes explicit how errors are reported to the end-user, whether the application still functions normally within the browser when certain aspects of the application platform are malfunctioning, and several other crucial parameters that has a bearing on the performance of the website.
Ease of Use
- JMeter is a powerful tool and yet remains easy to install and use. It is a pure-Java desktop application, with the look and feel of a web browser.
- However, it does not render HTML pages, or execute the Javascript found in HTML pages, as normal browsers do. Installation is easy.
- Simply download the latest version from its website. It is always better to opt for the last stable version from the many options available.
- The download is in .zip or .tgz, and it is necessary to unpack the archive to a local folder.
- JMeter comes ready-to-use, and most of the default settings work fine for the average user. For advanced users who want deep customization, reviewing the configuration settings is equally easy.
- The settings are available in the jmeter.properties file, located in the bin folder. The file is well documented and easy to read and change when needed. Starting JMeter is just a matter of double clicking jmeter.bat in the bin folder.
- It is also easy to obtain any additional jars as required. For instance, use of JMeter for JDBC, JMS or JavaMail requires additional jars which are not included in the core JMeter installation. However, the user guide on the website offers clear cut details on how to obtain the required additional jars and use it.
Extensive Documentation and Support to Build Test Plans
Another positive feature of JMeter is the extensive support available to build test plans, which makes the whole process a breeze. To test a SOAP interface layer all that is required is the URL and SOAP request. It is possible to develop the test plan starting with these basics and add on variables, counters, parameters, CSV files, loops, logs, and anything else. There are virtually no limits in designing the test and making it as maintainable as possible.
