Reduced our test operating costs, provides quick feedback, and helps us understand how to build better test cases
Overall, it's helped our ability to address test data challenges. The test data features on their own are very good, but version control test data isn't included yet. I think that's an area for improvement. We can update the test data on the cloud. That's a good feature. There's also test data management, which is good. [Runscope] doesn't have the test data management yet. Mock services do, and performance testing has it. We can do the same test through JMeter, validating the same criteria, but the feedback from [Runscope] is quite visible. We can see the request and the response, what data comes back, and add the validation criteria. We can manage the test environments and test data, but running the same API request for multiple test data is missing. We cloned the test cases multiple times to run it. They need to work on that. Version controlling of the test cases and the information, the ability to compare the current version and the previous version within [Runscope] would be really nice. The history shows who made the changes, but it doesn't compare the changes. In the future, I would like to see integrations with GitLab and external Git reports so we could have some sort of version control outside as well. There is no current mechanism for that. The ability to have direct imports of spoken API specifications instead of converting them to JSON would be nice. There are some features they could work on.

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.

Quotes from Members

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

Pros

"The product's initial setup phase was straightforward."
"The feature that stands out the most is their action groups. They act like functions or methods and code, allowing us to reuse portions of our tests. That also means we have a single point for maintenance when updates are required. Instead of updating a hundred different test cases, we update one action group, and the test cases using that action group will update."
"It has a unique programming dashboard that is very user-friendly."
"The product's most valuable features include its cloud-based nature, which allows us to conduct tests without relying on local resources."
"One thing that we are doing a lot with the solution, and it's very good, is orchestrating a lot of JMeter agents. This feature has helped us a lot because we can reuse other vendors' performance scripts that they have used with JMeter before."
"For me, the best part is that we can graphically see the test result at runtime. It helps us understand the behavior of the application during all stages of the test."
"The stability is good."
"They have good support documentation and when we have contacted them, they helped to guide us."
"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."
 

Cons

"Potential areas for improvement could include pricing, configuration, setup, and addressing certain limitations."
"The tool fails to offer better parameterization to allow it to run the same script across different environments, making it a feature that needs a little improvement."
"BlazeMeter should improve or make available some features out of the box that JMeter requires customization for."
"Lacks an option to include additional users during a test run."
"The scanning capability needs improvement."
"Version controlling of the test cases and the information, the ability to compare the current version and the previous version within Runscope would be really nice. The history shows who made the changes, but it doesn't compare the changes."
"The performance could be better. When reviewing finished cases, it sometimes takes a while for BlazeMeter to load. That has improved recently, but it's still a problem with unusually large test cases. The same goes for editing test cases. When editing test cases, it starts to take a long time to open those action groups and stuff."
"BlazeMeter should improve or make available some features out of the box that JMeter requires customization for."
"Need to add or support some more APIs in the Script Manager window."
"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."
"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."
 

Pricing and Cost Advice

"The solution is free and open source."
"The product pricing is reasonable."
"It's consumption-based pricing but with a ceiling. They're called CVUs, or consumption variable units. We can use API testing, GUI testing, and test data, but everything gets converted into CVUs, so we are free to use the platform in its entirety without getting bogged down by a license for certain testing areas. We know for sure how much we are going to spend."
"My company has opted for a pay-as-you-go model, so we don't make use of the free version of the product."
"It is an averagely priced product."
"The licensing fees are billed on a monthly basis and they cost approximately $100 for the basic plan."
"The pricing is manageable. It is not that big. Big companies won't mind the licensing costs."
"I would rate the pricing a three out of ten, where one is very cheap, and ten is very expensive."
"NetStorm is priced well when compared to many well-known tools."
