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.

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."

"The inside object repository is nice. We can use that and learn it through the ALM connection. That's a good feature. The reporting and smart identification features are also excellent."

"The interface is fine and there is nothing else to add in terms of enhancement."

"The OpenText solution is the best of breed and the best solution on the market for large customers."

"The scalability of Micro Focus UFT One is good."

"It is a stable solution."

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

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

"The ease of record and playback as well as descriptive programming are the most valuable features of UFT (QTP)."

Cons

"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."

"UFT still requires some coding."

"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."

"It could work with more browsers other than Internet Explorer, and could better handle new things like Ext JS."

"You have to deal with issues such as the firewall and how can the tool talk with the application, i.e., if the application is on a company network and so on. That, of course, is important to figure out."

"Previously, the product was a script-based solution. Presently, the tool offers non-script, no-code, or low-code functionalities, making it an area where improvements are required."

"The price is very high. They should work to lower the costs for their clients."

"One area for improvement is its occasional slowness."

"The AI feature needs improvement. For banking applications, we input formatted text from documents, but the AI feature is recognizing three fields as one field, e.g., for a phone number, it puts all 10 digits in the international code or country code. Then, the script fails."

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."

"OpenText UFT One is a very expensive solution."

"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 an expensive solution."

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

"The price is only $3,000. I don't know how many QA analysts you would have in any given company. Probably no more than five or 10. So if it's a large corporation, it can easily afford $15,000 to $25,000. I don't see that being an issue."

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

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

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