Performance testing for peak retail events has become faster and delivers reliable user load insights
BlazeMeter offers numerous features, but the ones that stand out to me include its ease of use, predefined configurations for high-scale performance testing that can be executed quickly, AI-powered testing, scriptless testing, and accurate API testing with an auto-correction plugin to ensure the accuracy of the tests performed. While I cannot pinpoint a single favorite feature, I find myself using parallel execution frequently because this feature allows multiple tests to be run at once, greatly enhancing my workflow. BlazeMeter effectively handles dependency in microservice architecture, for example, linking one API to another to manage response flows, such as the login and registration APIs, which flows efficiently through BlazeMeter. BlazeMeter has positively impacted my organization by reducing the time required for testing due to its robust features that yield efficient results. Unlike JMeter, which has limitations on user simulations, BlazeMeter allows me to test any number of users, helping my e-commerce website manage unpredictable traffic loads effectively while delivering accurate results I can trust to improve my systems.

Good reporting and interface, but supports limited types of protocols and requires low-level script editing
It should have more interfaces. In terms of interfaces or protocols, what you can do with Rational is far limited as compared to other products out there. What it does, it does great, but it only gives you limited types of protocols. It supports between 8 to 15 types of protocols, whereas other test tools give you 20 to 30 types of protocols with which you can do testing and convert to script. It records Javascript-based scripts, and you got to know a little bit of Java to basically be able to edit them, but the level of editing you got to do is very low. I like that, but the ability to edit the script is not as good as Parasoft or LoadRunner, which have C-Script.

Quotes from Members

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

Pros

"The solution offers flexibility with its configurations."
"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."
"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 product's most valuable features include its cloud-based nature, which allows us to conduct tests without relying on local resources."
"I really like the recording because when I use the JMeter the scripting a lot of recording it takes me a lot of time to get used to. The BlazeMeter the recording is quick."
"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."
"The baseline comparison in BlazeMeter is very easy, especially considering the different tests that users can easily compare."
"The extensibility that the tool offers across environments and teams is valuable."
"Reporting is pretty good. Its interface is also good. I'm overall pretty happy with the functionality and use of IBM Rational Test Workbench."
"This solution provides for API testing, functional UI testing, performance testing, and service virtualization."
 

Cons

"Integration with APM tools like Dynatrace or AppDynamics needs to be improved."
"The reporting capabilities could be improved."
"The pricing is high"
"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 support could be better."
"My only complaint is about the technical support, where sometimes I found that they would not read into and understand the details of my question before answering it."
"Lacks an option to include additional users during a test run."
"BlazeMeter should improve or make available some features out of the box that JMeter requires customization for."
"It should have more interfaces. In terms of interfaces or protocols, what you can do with Rational is far limited as compared to other products out there. What it does, it does great, but it only gives you limited types of protocols. It supports between 8 to 15 types of protocols, whereas other test tools give you 20 to 30 types of protocols with which you can do testing and convert to script. It records Javascript-based scripts, and you got to know a little bit of Java to basically be able to edit them, but the level of editing you got to do is very low. I like that, but the ability to edit the script is not as good as Parasoft or LoadRunner, which have C-Script."
"There are a number of things that they can do to simplify the tools, but the most important thing that they need to do is simplify the installation."
 

Pricing and Cost Advice

"It is an averagely priced product."
"The solution is free and open source."
"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 pricing is reasonable."
"We pay a yearly licensing fee for the solution."
"The licensing fees are billed on a monthly basis and they cost approximately $100 for the basic plan."
"My company has opted for a pay-as-you-go model, so we don't make use of the free version of the product."
"The pricing is a little bit on the higher side, although it is really good."
"It doesn't really concern me. Licensing is on a yearly basis."
