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 tool can be handled without any knowledge in parameterisation, especially the TestCaseDesign which makes the tool mighty and stable."
"Tosca BI is important to make sure that our data integrity is in check and validated; to make sure our data is good. Our data is the number-one important driver for our company, so if that's not good, we have some big problems."
"This solution is very easy to learn and any non-programmer or manual tester, with little experience in automation, can pick it up quite easily."
"I like how the modules are set up, particularly how you can use the screens you're automating. This automation helps save both time and money because we use less test capacity regarding personnel."
"We like the fact that it works across mobile, desktop, web, and APIs. Due to this, the solution has a broad range of applications."
"Tricentis Tosca can be easily integrated with SAP infrastructure."
"Very user-friendly and the low code automation is really helpful."
"We are satisfied with the support of Tricentis."
 

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."
"They can make it more stable. I have used this tool for SAP applications. They have an alliance with SAP, and it mostly worked fine, but there were a few glitches. However, we got the required support from the Tricentis team. They are coming up with their new versions and upgrades with respect to how the Tricentis systems as cloud applications are updated, and it would be good if they have a robust accelerator pack."
"I would like a better user interface."
"The UI does not have the option of automating the scroll bars."
"Product quality has declined as it grows, and its updates aren't without fault. The process of resolving problems has slowed, and as it expands into other areas like NeoLoad and other testing tools, the product becomes more complicated. It used to be a small firm with a clear goal, but as it grows, the quality has been affected."
"It is quite difficult to integrate the solution with other tools."
"A disadvantage of Tricentis Tosca is that you have to customize it according to your need, during the early stages of the software, particularly during upstream testing, before system and unit testing."
"The solution needs to improve its simulation of mobile environments. Right now, that aspect is really lacking."
"Security, UI, and basic performance improvements could be done to the product to enhance its use."
 

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."
"Tricentis Tosca should improve its pricing. It is expensive."
"I give the cost of Tricentis Tosca a six out of seven."
"Tricentis Tosca is an expensive solution and there is an annual license required. The whole licensing process is confusing and it could be made easier."
"There are different types of licenses: enterprise or professional. The cost varies."
"Pricing for Tricentis Tosca could be improved because it's very 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."
"Tosca is expensive. I don't see small and medium customers going for it. It's always large enterprises that have a big pocket. It is very expensive as compared to the other tools that we have in the market. They should reduce the price by half, and if they do that, they would do better business. From the competition perspective, other solutions are at a pretty similar level. UiPath is also very expensive. One thing that I always wanted was a short-term consumption license. With Tricentis, the biggest challenge is that you have to go for a minimum of one year license, and they also try to sell you a three-year license. It would be good if people can get a three-month or four-month consumption license."
"The pricing of the solution comes as part of our Tosca bundle."
