Selenium vs Jmeter: Which one to choose?

In order to understand and compare the application and usability between Jmeter and the Selenium framework from the point of view of a tester. It is very important for a tester to understand the basic requirements. In general JMeter and Selenium are both used for web application testing. But the key distinction is that JMeter is mostly used for testing the performance of web applications under load and stress. On the other hand, Selenium is well suited for automation and cross-browser testing of a website.

What is Jmeter?

JMeter is an open supply load and purposeful trying-out tool for diverse community protocols, run as Java computer software with a graphical interface. some of the supported protocols are JDBC database connections, FTP, LDAP, net services, WebSocket, JMS, HTTP, RTE, and time-honoured TCP connections. JMeter is advanced as a pluggable and extensible device suite with JMeter plugins, which allow advanced sampling and validation.

What is Selenium?

Selenium is an open-source useful checking-out framework that automates browsers. It provides multiple facilities for internet software trying out across one-of-a-kind browsers and structures. Selenium isn’t only a single device but a collection of software programs. The two most crucial elements of this suite are Selenium WebDriver and Selenium IDE. The first one is a set of language-particular APIs for browser automation. The second one is a Firefox/Chrome extension that gives a “file & replay” feature. Selenium scripts also can be recorded with the unfastened Chrome Extension.

Selenium scripts are specifically evolved as code, to gain the most benefit of WebDriver’s API. This API has bindings on various programming languages. Every net browser & operating system couple requires an exceptional driving force implementation. WebDriver is an abstraction layer that requires accurate motive force set up at the execution gadget.

The person can write in any of the supported languages to Selenium WebDriver’s API, which automates any of the supported drivers

Required Knowledge for Selenium

Selenium-based checking out calls for the know-how of WebDriver API. Moreover, it’s necessary to be gifted inside the selected developing language (e.g. Java, Python, C#, etc), develop a toolchain (e.g. Maven, Ant, MS visible Studio, etc) and operate a checking out framework (JUnit, TestNG, unit test, NUnit, etc). It is feasible to have a “test Library” module for simplifying the methods, but that still calls for training on. Selenium is likewise suitable for BDD.

Required Knowledge for Jmeter

JMeter-based totally testing requires knowledge of the JMeter component organization, or as a minimum ten fundamental additives. New builders ought to study environment setup and the required plugins in step with their take a look at project purpose. But, because JMeter has a GUI and doesn’t require scripting, it’s easier to run and learn.

while writing exams, check cases are not sufficient. As a substitute, builders and teams have to take a look at suite that aggregates take a look at scripts to assure take a look at insurance. That is additionally beneficial for test automation.

Not JMeter nor Selenium have built-in test aggregation abilities. However, there are solutions:

The JMeter test suite is a group of JMX scripts. A higher way to aggregate these scripts is to use Taurus, which may deal with them with YAML file. The JMX script files do no longer need to be refactored and they’re geared up to be aggregated into a YAML report. it is viable to customise parameter values handed to each JMX script inside the suite. moreover, it’s clear to split sports:

• Broaden a JMX script as usual (e.g. JMeter GUI)
• Aggregate JMX scripts with a YAML file in Taurus

Selenium may be used for a few overall performance trying out (e.g. limited bandwidth testing), however, it cannot be used to load take a look at with accuracy like JMeter. for example, Selenium can’t generate a managed wide variety of request for seconds because it does have an equivalent of JMeter’s steady Throughput Timer. furthermore, the use of a target request according to 2nd in JMeter requires fewer sources from the execution system, due to the fact Selenium attempts to instantiate many net browsers approaches.

JMeter can record precise internet sessions originated by way of internet browser applications (see take a look at Script Recorder and Blaze Meter Chrome Extension) and replay the net consultation because the server sees them. however, each replay does no longer reproduce consumer side elaboration (e.g. Javascript good judgment in net browser) or web web page rendering. So if our check is centered on how a web page is offered to a consumer, Selenium is a higher desire.

JMeter vs Selenium: Points of Differences

The Conclusion

Regardless of your responsibilities in Test Development and Automation, both Selenium and JMeter are useful and significant tools to be used while test project analyzing and execution. So have you decided the right tool for you and make sure you choose them based on your project goals.
