Although Selenium is designed for automating real-world tests in browser and JMeter is designed to perform load testing, in some cases, JMeter based tests may be enough to verify application functionality. These products don't directly compete with each other and it should be …
It has very powerful capabilities and for free!!! It's ease of use and installation and easy to get started are highlights. A lot of community support and youtube videos from JMeter developers to help you understand various functionalities within JMeter to support you. You can …
LoadRunner and Silk Test were the tools I used in the past to compare with JMeter. I thought LoadRunner had a more commercial appearance and it comes with HP support from your service provider. It also comes at a steep price. JMeter and LoadRunner have a similar learning curve …
QTP is a good tool to be used by beginner automation engineers with no prior experience in test automation. However unlike selenium, QTP is limited by its architecture and VB Script. Selenium allows for being integrated in any framework using any of the most popular languages …
All alternatives are not listed here (like QTP), but Selenium beats all of them because it's free, there are tons of guides and tutorials on the internet, and there are lots of extra libraries that use Selenium.
JMeter is well suited for Java applications where the user can script the scenario once and make changes to accommodate for as many numbers of users for load test execution. The image and selection of any files or exporting files scenario is handled well.
It is less appropriate to test Ajax applications where it is required to script click per use.
When you have to test the UI and how it behaves when certain actions are performed, you need something that can automate the browsers. This is where Selenium comes to the rescue. If you have to test APIs and not the frontend (UI), I would recommend going with other libraries that support HTTP Requests. Selenium is good only when you have no choice but to run the steps on a browser.
Easy of use - in generate load like HTTP requests, and processing/analyzing the responses. No coding is necessary at the basic level, just need to understand load testing and the infrastructure being tested.
Automatic management of things like cookies to help with session state support - so you don't specifically have to worry about it or handle it
Lots of testing/configuration options to suit your needs in making the right load generation (sampling requests), and analyzing the results, including any pre and post processing of the results first. Things like the Beanshell/BSF pre/post processors, response assertion, regular expression extractor, XPath extractor, CSV data set config
There is a JMeter cloud service called BlazeMeter that I think would be useful for those that need to scale up high load without provisioning their own systems. I've not personally tried it though, but I recently attended a meetup presentation that highlighted nice useful features that BlazeMeter provides. One should evaluate the service if they are considering JMeter and need to expand beyond existing hardware resources.
Jmeter requires many tweaks with respect to its configuration file and thread properties. users need to edit theses files themselves. There could be some interface where we can edit this fields.
Jmeter cannot handle more threads and hangs up when we increase the number of threads. This causes lot of inconvenience. In these situations, user can be notified that such change would be lead to slow performance so that user can do as required. The same appears when we try to view huge files on graph listener.
Jmeter should optimize the read and write access to output csv since it acts as overhead to the I/O performance. This affects our test results for the application which we are testing.
Selenium is pretty user-friendly but sometimes tests tend to flake out. I'd say roughly one out of twenty tests yields a false positive.
Selenium software cannot read images. This is a minor negative because a free plug-in is available from alternate sources.
Slowness may be a minor factor with Selenium, though this is an issue with basically any testing software since waiting on a site to execute JavaScript requires the browser to wait for a particular action.
Price, Wiki and user sharing. Having access to the information provided by the developers and other open source providers is key for me. The ability to share information and get answers directly is very important to success in software testing. And the price of this product currently is amazing. Too many companies charge way too much money for products that are far behind in their value and pertinence
We love this product mainly because of its high customization abilities and the ease of use. Moreover, its free and can be learned easily through online communities and videos. The tests are more consistent and reliable as compared to Manual tests. It has enabled us to test a large number of features all in one go, which would have impossible through manual tests. The reports generated at the end of the tests are really helpful for the QA and the development teams to get a fair view of the application.
I can jump right into a new test plan and start building from scratch. The natural progression from test plan to thread group and then designing the basic format of the process is very streamlined and smooth. With only slight modifications I can build out a very complex model from a very basic beginning.
As I mentioned earlier, the reason I use Selenium is because there is a fairly widespread community of users, and user support services are at a good level. because the application is open source, it works on many platforms (Windows, Linux, IOS) without any problems. In addition, it gives us a lot of options for writing functional tests. For errors that we receive through the application, we can easily find the reasons for errors in the forums.
I have been using JMeter for the last year. By using this tool, you can make sure the system will work under varied loads. It helps us to simulate real time scenarios by creating required virtual users and make sure the application will work under load. Perform load, stress, and stability testing using JMeter.
Selenium does not have technical support available easily. You have to go through forums to get the information you need. However, there are excellent forums out there that make it easy to troubleshoot. The open-source flexibility makes it difficult to have dedicated support.
We did everything we needed to use it. Now we can execute our tests on different operational systems and browsers running few tests simultaneously. We also implemented Appium framework to execute our tests on mobile devices, such as iPhones, iPads, Android phones and tablets. We use SauceLabs for our test execution and Jenkins for continuous integration.
I have used LoadRunner and Silkperformer, and so far Jmeter turns out be the easiest to use of all these. While each of them have their own ROI, Jmeter can be picked by anyone in hours and start testing within a day. While with other tools, we need to get license, install them (takes a while) and setup tests and firewalls, etc.
At the time of adoption, there were not many other alternatives that were even close to being competitive when it comes to browser testing. As far as I know now to this day, there is still little competition to Selenium for what it does. Any other browser-based testing still utilises Selenium to interact with the browser.
