Featured Reviews

KashifJamil - PeerSpot reviewer
Good integration with other tools, stable, scales easily
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. This includes the workbench as well as the other tools. In the future, I would like to see the other types of tests supported, that are not already covered in the DevOps approach. This would include, for example, penetration testing.
PrabhuKrishnamoorthy - PeerSpot reviewer
Has transformed testing by reducing scripting effort and enhancing productivity with advanced features
The self-healing feature of Tricentis Tosca needs significant improvement. Currently, it is static and not dynamic. For example, if a button in an application changes, Tricentis Tosca should be smart enough to detect the change and still execute the script seamlessly. Improvements are needed to ensure it responds dynamically to changes in the application.

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."
"The technical support is good, we were satisfied."
"It's stable and reliable."
"The most valuable features of Tricentis Tosca are the Salesforce scanning. There are two scanning for Salesforce applications. There is Salesforce scanning and normal application scanning. Object identification has been really useful in Tricentis Tosca."
"The most valuable features of Tricentis Tosca are all the test automation functionality. It is a full-scale automation tool."
"The model-based scriptless automation is the most valuable feature because it needs less maintenance as compared to script-based automation."
"I would rate the scalability a nine out of ten. We have enterprise-level customers."
"Good use in Agile workshops, where the person needs to conceptualize the tests before the developer provides the complete application interface."
"I am impressed with the product's script test."
 

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. 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."
"First, Tricentis could improve Tosca's Linux scripting. We can automate Linux scripting, but there are a few commands that Tosca doesn't support. DVS support and the object identification mechanism could also be better."
"In Tricentis Tosca, we need to capture the element each time. If they could implement an auto-heal feature, it would capture automatically by detecting it from the page."
"The product's test case management functionality needs enhancement."
"One thing to improve in Tricentis Tosca is that it's not compatible with Excel based forms. Another area for improvement is that the tool is not compatible with OpenText applications. The support and licensing cost for it also need improvement. The tool also needs cloud support, as it's currently on-premises only."
"The Vision AI implementation works very slowly, affecting the speed of our work."
"I would like to see something in terms of AI capabilities."
"They should have a different license policy for medium and small companies."
"It would be of great help if they can fix the loading or performance issues. Sometimes, when I create the test case folder and test cases, it feels like it has loading or performance issues. When passing the objects, we can't sometimes find the exact element. We need to find out that exact location and just give the path for that, and then it works. In the pipeline, when creating Jenkins, we create the list execution for passing the execution list to the commander. I feel it is a bit late, by a fraction of seconds. I first thought it could be my mistake or a setting issue, but I worked on that, and it's not a mistake or a setting issue."
 

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 tool's pricing is lower than that of other automation tools."
"There are different types of licenses: enterprise or professional. The cost varies."
"​It is an expensive tool compared to other test automation tools. It has a lot of advantages over other tools."
"It is expensive."
"If you are purchasing less than five licenses, then the pricing is high. On a scale from one to ten, with one being low and ten being high pricing, I would rate this solution at eight."
"The price of Tricentis Tosca is approximately Є10,000 for one license. However, it used to be much cheaper, but they changed their license structure. It used to be a structure where if you bought a license you would receive one year of free support and maintenance. Now they only have a yearly license, and that is expensive."
"I would like to see better costing packs. There are several features but USD $11,000 for one license is expensive."
"I am satisfied with the cost."
