The key questions I would pose are: how high of a concurrent load do you need to generate against the system? How technically skilled are your personnel that will perform the load testing? How much programmable/scripting/code based control do you desire from the tool? Do you prefer more of a GUI based tool or a programmatic code/scripting based tool? JMeter will be for those that want a GUI, moderate to low scripting/code based control/programmability, moderate to low load generation, and for users experienced in the novice to expert range.
Visual Studio Test Professional is best for .NET and C# based development, which is what 90% of our developers and projects do. It is an integral part of the CI/CD pipeline for our custom made Enterprise resource planning tool. It also works very well with Azure providing seamless integration to way more functionality.
Easy to construct Webservices script - You just need to add a sampler with the endpoint, payload and header information. And boom you can run a load test on the service with varying load and capture the response time and throughput. In a commercial tool like Loadrunner or Silkperformer, this process would take at least couple of hours, while with Jmeter we can do this in 10 minutes or less.
Modularizing the scripts - Jmeter has a very good way of organizing the scripts and the reusability of the existing script (transactions) is also as easy as copy pasting the script.
Jmeter tests can be run from anywhere, so you can run it from the idle webserver itself if you have some firewall restrictions to test it from your local or other environment.
Jmeter distributed tests can be spawn from the AWS and results collated to see the performance from different regions in the world.
Even though it has very easy installation, you can run into issues easily. I was ab;e to trigger a test at browser level but couldn't stop the tests. I had to kill it from task manager and then had to reinstall from begining.
There are so many things in JMeter you can do especially with the sampler for selenium for UI tests. More documentation/webinars etc.. would help the community better.
The jmx files should have an easy way to be integrated with ci/cd tools and cloud.
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
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.
Visual Studio Test Professional's overall usability is extremely high quality. It is extremely functional and like all Microsoft products has a user interface that is well designed and is extremely user friendly. Any functionality which I looked for, I was able to either understand immediately or find a user guide online.
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.
My team has always been able to troubleshoot with the help of customer support (and even schedule a virtual meeting!) in a timely manner. The support is provided immediately and with the necessary knowledge to answer/solve any questions/problems I or my team experience.
I have evaluated LOADUI (web free version) and it was a very unstable tool and I could not rely on those results completely as I was not sure how the tool was performing. It only generated the top 10 less transaction times and when Jmeter was in use, it was very effective in using plugins to accommodate more outputs.
When using Azure Devops, it only has a basic test plan while using the extension, and it is better suited if you only use Azure Devops, but VS test professional provides comprehended test execution and management as most of the developers and testers use Visual Studio to develop their apps and publish their builds.
It helped to estimate resources required for a particular client requirement. For example if the client wants the application to be used by 500 users for 1 hour, based on the load test we perform for 500 users and 1 hour we recommend resources and their capabilities.
Jmeter was used to identify bottleneck. This would lead to better performance.
Visual Studio Test professional fits right in with the other Microsoft Lifecycle Management tools.
End to end, Development, Test, Deployment and Delivery assures the pipeline is continuous. Visual Studio Test Professional is an integral part of that pipeline.
Familiarity with Microsoft Tools makes usability intuitive, makes it easy to ramp up our Testers.
