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.

IDE is simple and it's quick to complete the process but the reporting is complicated

You pay for the number of users that you're going to be utilizing. In order to scale up, you would have to pay for additional users, but for our use case, we're able to scale fairly easily. We have a license for 500, but we're using half of that for our initial workflow. For maintenance, as far as I'm aware, there's only one person really working on the maintenance of it and we only really have one user consistently using the software. He's a QA person. We don't have any plans to increase our usage. Even though we've had it for a while, we have a major push to start utilizing it more. I imagine we'll probably be using it and utilizing it across our QA team in the next year. We're in the process of determining whether we're going to keep it or not due to the fact that it is so expensive. That's why I've been researching alternatives for the RadView.

"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."

"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."

"All IBM testing tools are really well integrated."

"The most valuable feature of this solution is reporting; it is interesting, intuitive, and we can do some parameterization."

"Technical support has been excellent, responsive, and helpful in trying to work through issues and questions."

"The solution is simple and useful."

"The tool itself is very viable for us."

"They are the best of all of the vendors I deal with, hands down."

"The analytics pack is probably one of the most powerful tools that I've seen."

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."

"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."

"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."

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

"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."

"When it finds a problem with response times, it doesn't specify exactly where the problem actually is."

"They can improve in the reporting - the ability to generate custom reports."

"I would like to be able to edit a scenario instead of re-recording a scenario."

"We have had a lot of trouble with this solution, and it is actually adapted to our application."

"The reporting side of things is really complicated. It's difficult to get out exactly what you're looking for, there are almost too many options."

"There is no analytical dashboard."

"We did have an issue with some of the script working incorrectly in our higher environments."

"Well there’s one issue when I have five or six scripts-- you have to set up different percentages and the number of connections and users, no matter how I tweak it seems that when I have one of the load scripts in the mix set, a percentage of less than 8-10%, there’s a probability that it won’t run at all."

More RadView WebLOAD cons

Pricing and Cost Advice

"It doesn't really concern me. Licensing is on a yearly basis."

"The pricing is a little bit on the higher side, although it is really good."

"It costs $8,600 yearly and we have the Cloud, which is an additional $800. Our perpetual license is $800 and then the Cloud functionality with our 500 users is the $8,600."

"We purchased a license for two years."
