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

"This solution provides for API testing, functional UI testing, performance testing, and service virtualization."

"Reporting is pretty good. Its interface is also good. I'm overall pretty happy with the functionality and use of IBM Rational Test Workbench."

"It is very simple to use, and the scripting language is even easier."

"With certainty, the best feature of UFT is its compatibility with so many products, tools and technologies. It is a challenge currently to find a single tool on the market besides UFT that will successfully work for so many projects and environments. For example, UFT supports GUI testing of Oracle, PeopleSoft, PowerBuilder, SAP (v7.20), Siebel, Stingray, Terminal Emulator, Putty, and Windows Objects (particularly Dialog Boxes). Furthermore, UFT has the built-in functionality to import Excel input files."

"With frequent releases, using automation to perform regression testing can save us huge amount of time and resources."

"The production and the efficiency of making your test cases can be very high."

"It's easy to use for beginners and non-technical people."

"OpenText UFT One offered valuable features by allowing us to build up libraries to streamline repetitive tasks, making scripting much easier."

"We have used it for the web and Windows-based applications. It is very productive in terms of execution."

"I like the fact that we can use LeanFT with our UFT licenses as well."

"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.

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."

"The tool needs to improve its performance since it can become heavy."

"Jumping to functions is supported from any Action/BPT Component code, but not from inside a function library where the target function exists in another library file. Workaround: Select search entire project for the function."

"The solution does not have proper scripting."

"I'd like to see UFT integrated more with some of the open source tools like Selenium, where web is involved."

"The solution is expensive."

"The artificial intelligence functionality is applicable only on the web, and it should be expanded to cover non-web applications as well."

"One of the drawbacks is that mobile performance testing is in need of improvement."

"It should consume less CPU, and the licensing cost could be lower."

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."

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

"HPE recently extended the demo license period from 30 days to 60 days which was a very wise and popular decision to give potential customers more time to install it and try it for free. Even if your company has a salesperson come in and demo UFT, I would highly encourage at least one of your developers or automation engineers to download and install it to explore for themselves the functionality and features included during the demo trial period."

"It's a yearly subscription. There are no additional costs to the standard subscription."

"The price is one aspect that could be improved."

"OpenText UFT One is a very expensive solution."

"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."

"It's an expensive solution."

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