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."
"It's a simple tool, particularly in terms of system testing. You can also convert and automate using Tricentis Tosca with ease."
"For beginners, the product is good, especially for those who are interested in the quality side of software testing."
"Makes optimal use of Model-based Test practice in getting Object-references from the application."
"The solution has plenty of features compared to other solutions."
"I would rate the scalability a nine out of ten. We have enterprise-level customers."
"As a codeless automation tool, the product offers a user-friendly experience without requiring extensive coding knowledge. Users can easily handle various applications, including web applications, SAP applications, Windows applications, and even Salesforce applications, without manual coding."
"Very user-friendly and the low code automation is really helpful."
"The most valuable features of Tricentis Tosca are the ease of use, you do not need to program if you do not want to."
 

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."
"It requires some coding customization that requires expertise."
"Needs a UI to visualize the test case development."
"Setup wasn't that straightforward; it was more complex. It all depends on the environment, because there were a lot of errors on our applications. Therefore, it wasn't an easy setup for us."
"Parallel execution is not yet implemented for Tosca. This means you can't execute the same test case on multiple machines remotely."
"In Tosca, I see that there are no user guides."
"Their license management should be improved. One of our customers is a global customer. They want to use one licensed server and then split the licenses based on the different users of the different business units, but currently, there is only one license server that everybody can access. There is no control, and that's why sometimes congestion can happen."
"While the initial setup was straightforward, we required assistance with the configuration to ensure that everything was done correctly."
"The product needs to improve object identification. The identify with properties and anchor methods work perfectly, while the by-index and image methods may face challenges."
 

Pricing and Cost Advice

"It doesn't really concern me. Licensing is on a yearly basis."
"The pricing is a little bit on the higher side, although it is really good."
"The tool is expensive. It has become overpriced, especially after Tricentis Tosca grew as a company. Initially, we bought a license with an annual support fee, which wasn't too expensive. However, they changed the model, and now we have to purchase a license yearly, which has become quite costly."
"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."
"It is expensive."
"Although the product is slightly more expensive than tools, its automation capabilities and reduced scripting needs justify the cost."
"It is expensive. There is also the training cost, but it does speed up the process. So, you get a return on investment."
"The tool's pricing is lower than that of other automation tools."
"The pricing of the solution comes as part of our Tosca bundle."
"Pricing could be better."
