Executive SummaryUpdated on Dec 15, 2024

IBM Rational Test Workbench and BlazeMeter are competing in software testing tools. BlazeMeter seems to have the upper hand due to its scalability and integration with open-source tools.

Features: IBM Rational Test Workbench offers extensive test automation for web, desktop, and mobile, excellent integration within IBM’s ecosystem, and robust functional testing capabilities. BlazeMeter provides powerful load testing, seamless Agile and DevOps integration, and cloud-based test execution, allowing for easy simulation of realistic world traffic and continuous testing with minimal setup.

Room for Improvement: IBM Rational Test Workbench could improve by simplifying its complex setup, enhancing cloud support, and streamlining customer onboarding. BlazeMeter may enhance its test data management features, support more detailed functional testing, and improve reporting integration within teams lacking advanced technical skills.

Ease of Deployment and Customer Service: Deploying IBM Rational Test Workbench can be complex and require significant time due to its wide feature set, though it offers comprehensive support. BlazeMeter’s cloud-based architecture ensures quick deployment and seamless integration, with efficient customer service and support through cloud flexibility.

Provides global load simulations without managing infrastructure and offers built-in reporting features

BlazeMeter should improve or make available some features out of the box that JMeter requires customization for. The licensing cost is also a concern since BlazeMeter is not free like JMeter, which limits its use. Additionally, if there is no host in preferred locations such as some Asian or Middle Eastern countries, it might not be convenient to use BlazeMeter.

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

"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."

"Its most valuable features are its strong community support, user-friendly interface, and flexible capacity options."

"The stability is good."

"The on-the-fly test data improved our testing productivity a lot. The new test data features changed how we test the applications because there are different things we can do. We can use mock data or real data. We can also build data based on different formats."

"Running from the cloud with load distribution, exhibiting load from different geo-regions. Generating the load from different cloud regions is the best feature."

"It's a great platform because it's a SaaS solution, but it also builds the on-premises hosting solutions, so we have implemented a hybrid approach. BlazeMeter sets us up for our traditional hosting platforms and application stack as well as the modern cloud-based or SaaS-based application technologies."

"BlazeMeter can be used for both API and performance testing, it is a multi-facility tool."

"The solution offers flexibility with its configurations."

More BlazeMeter pros

"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

"The only downside of BlazeMeter is that it is a bit expensive."

"A possible improvement could be the integration with APM tools."

"The should be some visibility into load testing. I'd like to capture items via snapshots."

"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 Timeline Report panel has no customization options. One feature that I missed was not having a time filter, which I had in ELK. For example, there are only filter requests for a time of less than 5 seconds."

"The customer service is not available 24/7, which affects its rating. I would rate it as a seven because they respond once they are available."

"BlazeMeter should improve or make available some features out of the box that JMeter requires customization for."

"We encountered some minor bugs, and I would like to have the ability to add load generators to workspaces without having to use APIs. We can't do that now, so we're beholden to the APIs."

More BlazeMeter cons

"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.

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

"The product pricing is reasonable."

"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."

"I would rate the pricing a three out of ten, where one is very cheap, and ten is very expensive."

"The pricing is manageable. It is not that big. Big companies won't mind the licensing costs."

"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 solution is free and open source."

"The overall product is less costly than our past solutions, so we've absolutely saved money."

More BlazeMeter pricing and cost advice

"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."
