Is user-friendly and offers live monitoring

Extending the same cloud tool to make it app native so that it can help with device performance testing towards HTTP requests and responses. If you can have a front-end tool like Google's Core Web Vitals, it would be great. If you have some integration with Google's Core Web Vitals, it would be great. I want the tool to have IP spoofing because whenever you do load testing, you will have a little bit of static IP based on a particular load generator. If we have an option of just making the real-time scenario, like having IP spoofing, and the range of IPs dynamically gets changed with the request just to mimic the real-time user behavior, then it would be a good improvement. Having integration to APM tools, like Dynatrace or AppDynamics, the way we have in the load tools, would be good.

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 is very stable."

"From my own experience, if you're talking about load testing and performance testing then definitely you should go for CloudTest. Because when we compared CloudTest with Performance Center, cost wise it was a better solution. It is easy to use as well, and you can definitely get an automation engineer or a performance engineer with very little exposure to any programming or scripting language such as JavaScript. I would definitely recommend this solution and would rate it at eight on a scale from one to ten."

"The tool is very user-friendly, so you can save a lot of time in terms of your preparation activities."

"The level of support is quite good and the integration is also very flexible."

"From my own experience, if you're talking about load testing and performance testing then definitely you should go for CloudTest."

"This is an awesome performance testing tool for web based applications, able to generate load multiple geographies, dynamic ramp-up to any levels of virtual users."

"Soasta CloudTest is an integral part of our performance testing strategy and key in generating load across geography."

"Customer service is great; quick to act on everything."

More Akamai CloudTest pros

"All IBM testing tools are really well integrated."

"IBM Rational integrates the testing software as Rational Test Workbench, which is quite convenient and efficient as it is able to automate the test scripts."

"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."

"Using service virtualization, we are able to accelerate the testing and development activity."

Cons

"One of the challenges with Soasta is availability and quick access to their technical support documentation and on-call support."

"I couldn't say, as I haven't used it outside the training or applied it to any project yet."

"Out of five, I would rate the technical support of the solution at two or three. Sometimes it's a challenge because we face delays."

"It's a manual process to whitelist respective internal IPs in coordination with web operations team to access Soasta. Availability of any standardized tool from Soasta will make setup process easy."

"The test clip should be more user-friendly."

"The UI gets stuck sometimes; pulling huge load test data takes time and the UI often gets stuck."

"In terms of improvement, I think integration of these tools with the leading EPM tools would be good. It would help to seamlessly integrate to Dynatrace or AppDynamics to understand what the profiling looks like when generating a load."

"Resource consumption also needs to be worked on. When we generate a thousand or two thousand concurrent users, we need to optimize the load generator resource utilization."

More Akamai CloudTest 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."

"Implementing custom functions is bit tedious job, as ECMA script does not support some of the standard java-script functions, Also the Script editor window is not user friendly."

"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."

"Rational Performance Tester supports cloud technology in the version 8.7, playing test scripts back on the cloud is not stable."

Pricing and Cost Advice

"We have a yearly license, and I would give it a rating of three out of five."

"The tool's price is at an intermediate level. When you compare it with other enterprise load testing tools, it falls under the average category."

"Running cost is very low."

"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."
