IT Specialist, ITE at a government with 10,001+ employees

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.

Kevin Copple

Sr. Quality Assurance Project Manager at a tech services company with 501-1,000 employees

Has supported faster test execution and increased flexibility while offering room to improve support responsiveness

Reducing the levels of support is something they could continue to improve. They tend to have an entry-level person that may not be as familiar with the product that fields the calls, which creates another day of delay to get to the level that's needed. This is a common practice across most companies where you call, you get the entry-level person, and then they work their way up to help screen calls so that they are more focused.

Quotes from Members

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

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."

"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."

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

"All IBM testing tools are really well integrated."

"Has improved our organization by allowing us to obtain fast, detailed information about the behavior of our products and to supply this to the customer, enabling us to work together without the need for special programming knowledge."

"This product is easy to use, understand, and maintain."

"Automation of tests is done very fast with UFT One."

"The most valuable feature is that it is fast during test execution, unlike LoadRunner."

"Record and Replay to ease onboarding of new users."

"A key benefit, obviously, is in terms of effort savings that we have achieved using UFT."

"UFT provides object identification, which is one of the easiest to use."

"Object Repository Technology, which is a good mean to identify graphical components of the applications under test."

"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."

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

"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."

"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."

"The scripting language could be improved. They're currently using Visual Basic, but I think that people need something more advanced, like Python or Java."

"We have had some issues with stability, where it crashes sometimes."

"The overall design needs an entire overhaul. We prefer software designed to ensure the package isn't too loaded."

"They should include an automated feature to load backlog tests."

"I would not recommend this solution to others who are considering it."

"We frequently encountered stability issues when the browser dependency caused Windows to consume memory without releasing it, leading to crashes during regression testing."

"There will be performance degradation on the test environment due to long continuous executions of automation scripts which leads to inconsistency of results, a better way to resolve this problem should be addressed at some point."

"Needs to improve the integration with the CI/CD pipeline (VSTS and report generation)."

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."

"The way the pricing model works is that you pay a whole boatload year one. Then, every year after, it is around half or less. Because instead of paying for the new product, you are just paying for the support and maintenance of it. That is probably one of the biggest things that I hear from most people, even at conferences, "Yeah, I would love to use UFT One, but we don't have a budget for it.""

"It took about five years to break even. UFT is costly."

"The licensing cost is high. There are no additional costs to the standard license."

"It's an expensive solution."

"Compared to other products, the solution is very expensive."

"The pricing of the product is an issue."

"We have ALM licensing, and the tool is free of cost."

"For the price of five automation licenses, you simply would not be able to hire five manual testers for two years worth of 24/7 manual testing work on demand."
