Performance Architect at Kohl's

Has monitoring capabilities integrated into it to see the performance of components while the test is in the running phase

NetStorm can generate high load with a single machine. Its Runlogic feature is very useful to send load to cover each and every flow of the application. NetStorm gives the feasibility of generating load with multiple load arrival models helping components to be tested based on its usage. NetStorm has monitoring capabilities integrated into it to see the performance of components while the test is in the running phase. One more great functionality is the ability to control the load runtime by increasing or decreasing the virtual users or pausing the users to keep on repeating the transactions without exiting.

Test Manager at Happiest Minds Technologies

Open-source and flexible but needs client-side scripting

It's an open-source tool and supports a lot of plugins and custom code, which allows integration with other tools like Azure and AWS. Also, the APIs tested with SoapUI can be directly used, avoiding the need to create collections like in Postman. The client-side scripting, if incorporated, would provide a complete solution for performance tests. It can handle user distribution and transaction throughput distribution effectively.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:

Pros

"Over the past decade, the product team has continued working on improving and enhancing their tools."

"Designs dynamic scripts and scenarios, as per our requirements, which is one the most important feature available in NetStorm. It helps us to do performance testing of our application in a periodic way."

"This tool helps to focus on real-time transactions that occur at a very high rate."

"NetStorm can generate high load with a single machine. Its Runlogic feature is very useful to send load to cover each and every flow of the application. NetStorm gives the feasibility of generating load with multiple load arrival models helping components to be tested based on its usage."

"NetStorm had made Kohls.com very stable in the ATG platform as well as a cloud platform that Kohls didn't have any issues during the major holiday season like Thanksgiving, Black Friday and Cyber Monday."

"ReadyAPI automation can help us validate the functionality of most web services, allowing us to find out the exact number of defects before deployment to the user interface."

"It stores good reports, as in, improved reports if compared with the SoapUI. It also has in-built security. You just need to switch and check the security testing. My team has never used it, but I know ReadyAPI provides those facilities as well."

"We find the product to be scalable."

"he initial deployment process is easy."

"It's an open-source tool and supports a lot of plugins and custom code, which allows integration with other tools like Azure and AWS."

"Eventually, we enhanced the whole automation, and how it should get integrated with the hardware, or another tool like Jenkins for CI/CD automation."

"We can scale."

"It has helped improve productivity and functionality."

Cons

"In the next release, we are looking for a JS instrumentation feature that would be helpful in identifying client-side issues at an early stage, or during testing."

"NetStorm is a powerful tool but needs more information to be available on the Internet and Youtube on how to use it."

"Need to add or support some more APIs in the Script Manager window."

"The user interface had to be improved for the product. Its user interface should be made simple and easy to customize as per user needs."

"This solution could be improved by offering artificial AI testing in addition to API testing. For example, we would like to have machine learning testing because when test applications, manual work could be completed automatically using this functionality."

"It is very slow sometimes."

"The solution’s interface could be improved."

"This is an area for improvement with the tool. We unnecessarily use JMeter for some website testing, which we would like to avoid by introducing this tool for API and load testing because it provides load testing features."

"The client-side scripting mostly isn't needed for performance testing, however, if implemented, it would enhance the tool."

"We need some time to understand and configure the solution."

"I want the solution to be able to monitor Apache Kafka activity as well."

"I'd not sure if they have the same level of documentation for performance and security testing."

Pricing and Cost Advice

"NetStorm is priced well when compared to many well-known tools."

"This solution operates on a licence basis and the usage and cost varies according to the use case. It is more expensive if you include access to the learning center. On average it costs approximately 800 Euros."

"ReadyAPI Performance’s pricing is reasonable."

"We find the cost to be affordable."
