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."
"Software testing tool that has multiple features. It's good to use for SAP testing, and it helps reduce test execution time."
"This solution is easy to use for everybody, including those who are not IT-educated."
"The most valuable features of Tricentis Tosca are all the test automation functionality. It is a full-scale automation tool."
"To me, what stands out the most about Tricentis Tosca is that even if I'm not a technical tester, I could pick up on how to use it very quickly because of the mechanisms of the tool, for example, its scanning mechanism. I'm not so technical, but I'm able to maneuver through Tricentis Tosca and derive capability. It's a user-friendly tool. It's not very complex."
"It's been very helpful to have connectivity with mobile. The tool also identifies some of the actual changes from the recordings on the actual testing suite. That is something that I really like."
"You can push transactions through to live, and you can intercept some transactions and return them back with mocked data."
"Makes optimal use of Model-based Test practice in getting Object-references from the application."
"The tool can be handled without any knowledge in parameterisation, especially the TestCaseDesign which makes the tool mighty and stable."
 

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. 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."
"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."
"You need to spend much more time learning the tool and how to use it, compared to others."
"I would like to see something in terms of AI capabilities."
"I would like to see better integration with other testing tools."
"Very difficult to get information about licensing costs."
"The product needs to improve its pricing. It also needs to improve the infrastructure and DEX agent setup."
"Tricentis Tosca’s technical support could be improved."
"Tricentis Tosca could improve on its mobile automation solution."
 

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."
"Expensive, but for long-term projects, it is paying back."
"The pricing is high, but altogether it offers you the ability to automate all sorts of applications: desktop, web, mobile, etc."
"Although the product is slightly more expensive than tools, its automation capabilities and reduced scripting needs justify the cost."
"The licensing cost for Tricentis Tosca is expensive. It has multiple features, but to use all of its features, you have to pay for additional licenses."
"Pricing could be better."
"A competitor of Tricentis Tosca: Katalon Studio, is very similar and offers lower pricing, though Tricentis Tosca offers more features and benefits."
"In terms of the licensing costs for Tricentis Tosca, we are spending more or less $70,000 per year. We have a very complex mechanism because there are some business users and some BI users, so the licensing structure is not simple, but support is included."
"The tool is quite expensive."
