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.

Offers good scalability and has the ability to integrate with various systems and services
One area where k6 could improve is by introducing a GUI similar to JMeter. While k6 is a powerful tool for performance testing, it leans heavily towards coding. Having a GUI, even if it is a low-code approach, could make it more accessible to a broader audience. It would be beneficial to strike a balance where basic tasks can be performed graphically through a user-friendly interface, while still allowing the flexibility for more complex operations through code, similar to how JMeter operates. This could enhance the user experience and make k6 more approachable for those who may not be as comfortable with scripting.

Quotes from Members

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

Pros

"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."
"The solution offers flexibility with its configurations."
"The stability is good."
"With the help of the Mock Services, we are overcoming everything. Wherever we are facing issues, whether they will be long term or temporary, by implementing the Mock Services we can bypass the faulty components that are not needed for our particular testing."
"In our company, various teams use BlazeMeter, particularly appreciating its cloud license software, which supports up to 5,000 users. BlazeMeter's cloud capabilities allow us to load test or simulate traffic from any location worldwide, such as Europe, North America, South America, Australia, and even specific cities like Delhi. So, with one cloud license, we can simulate user load from various locations globally."
"The baseline comparison in BlazeMeter is very easy, especially considering the different tests that users can easily compare."
"Using cloud-based load generators is highly valuable to us, as we can test from outside our network and increase load generation without having to upscale our hardware as much. The cloud load generator is there when we need it and is the feature we leverage the most."
"The most valuable feature of the solution is its ability to run high loads and generate reports."
"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

"The scalability features still need improvement."
"Integration is one of the things lacking in BlazeMeter compared to some newer options."
"The product currently doesn't allow users to run parallel thread groups, making it an area that should be considered for improvement."
"BlazeMeter needs more granular access control. Currently, BlazeMeter controls everything at a workspace level, so a user can view or modify anything inside that workspace depending on their role. It would be nice if there was a more granular control where you could say, "This person can only do A, B, and C," or, "This user only has access to functional testing. This user only has access to mock services." That feature set doesn't currently exist."
"The scanning capability needs improvement."
"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."
"The product could improve in areas such as mobile testing and the integration of AI analytics."
"In terms of improvement, I would like to have the ability to customize reports."
"One area where k6 could improve is by introducing a GUI similar to JMeter."
 

Pricing and Cost Advice

"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."
"It is an averagely priced product."
"The pricing is manageable. It is not that big. Big companies won't mind the licensing costs."
"The overall product is less costly than our past solutions, so we've absolutely saved money."
"The product isn't cheap, but it isn't the most expensive on the market. During our proof of concept, we discovered that you get what you pay for; we found a cheaper solution we tested to be full of bugs. Therefore, we are willing to pay the higher price tag for the quality BlazeMeter offers."
"The licensing fees are billed on a monthly basis and they cost approximately $100 for the basic plan."
"When compared with the cost of the licenses of other tools, BlazeMeter's license price is good."
"We pay a yearly licensing fee for the solution."
