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.

Lighter on the RAM and has native Grafana support
The tool's big advantage is that it is more performance-test oriented for experienced testers who know what they are doing. In a normal working setup, performance engineers frequently work with DevOps and development teams. For these teams, k6 Open Source's syntax is much simpler and easier to understand and apply in the working process. Recently, I had a case where I was using another tool, and there wasn't enough memory for it because it required more RAM. k6 Open Source, on the other hand, is lighter and doesn't have a UI, which is beneficial. An engineer I was training could use k6 Open Source scripts even without my help. The tool is more efficient and has native support with Grafana, as both are developed by the same company. This integration enhances monitoring and loss ratio tracking. Thanks to its intelligent GUI, k6 Open Source's design is simpler, particularly for complex scenarios. When we need to manage hundreds of thousands or millions of transactions per minute, the solution becomes a game-changer compared to JMeter.

Quotes from Members

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

Pros

"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."
"The most valuable features of the solution stem from the fact that BlazeMeter provides easy access to its users while also ensuring that its reporting functionalities are good."
"BlazeMeter has allowed us to simplify and speed up our load testing process."
"It supports any number of features and has a lot of tutorials."
"The orchestration feature is the most valuable. It's like the tourist backend component of BlazeMeter. It allows me to essentially give BlazeMeter multiple JMeter scripts and a YAML file, and it will orchestrate and execute that load test and all those scripts as I define them."
"BlazeMeter can be used for both API and performance testing, it is a multi-facility tool."
"Running from the cloud with load distribution, exhibiting load from different geo-regions. Generating the load from different cloud regions is the best feature."
"The solution offers flexibility with its configurations."
"The tool's big advantage is that it is more performance-test oriented for experienced testers who know what they are doing. In a normal working setup, performance engineers frequently work with DevOps and development teams. For these teams, k6 Open Source's syntax is much simpler and easier to understand and apply in the working process."
"The standout feature of k6 is its strong focus on API performance testing."
 

Cons

"In terms of improvement, I would like to have the ability to customize reports."
"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."
"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."
"BlazeMeter does not provide integration with the Aternity tool."
"If the solution had better support and the documentation was efficient it would do better in the market."
"BlazeMeter has room for improvement in terms of its integration with GitLab, particularly in the context of CI/CD processes. While it has multiple integrations available, the level of integration with GitLab may need further enhancements. It is known to work well with Git and Jenkins, although the extent of compatibility with GitLab is uncertain."
"I believe that data management and test server virtualization are things that Perforce is working on, or should be working on."
"Integration with APM tools like Dynatrace or AppDynamics needs to be improved."
"One area where k6 could improve is by introducing a GUI similar to JMeter."
 

Pricing and Cost Advice

"The solution is free and open source."
"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."
"I would rate the pricing a three out of ten, where one is very cheap, and ten is very expensive."
"When compared with the cost of the licenses of other tools, BlazeMeter's license price is good."
"I rate the product's price two on a scale of one to ten, where one is very cheap, and ten is very expensive. The solution is not expensive."
"The licensing fees are billed on a monthly basis and they cost approximately $100 for the basic plan."
"We pay a yearly licensing fee for the solution."
"The product pricing is reasonable."
