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."
"We like the fact that it works across mobile, desktop, web, and APIs. Due to this, the solution has a broad range of applications."
"You can quickly build automated testing, manage it, and have it run on a regular basis to ensure that there are no issues."
"The low code is the best feature."
"It's integrated with different technologies, desktop applications, package solutions like SAP, and mobile applications."
"Tosca is a low-code no-code automation tool, allowing direct automation and reusability of test cases."
"What I find valuable is that Tricentis is always refining the test methodology. They listen to feedback from the analysts about what the testing tool should do, and then Tricentis always implements it. So all the necessary testing functions are already implemented in their tools."
"It is easy to maintain and easy to automate. No coding skills are required to automate. It is also easy in terms of transferring knowledge and skills. Many of my team members shifted over the past one and a half years, and there was no big issue with respect to knowledge sharing. It is a good tool that enables me to re-automate my scripts and update my scripts as quickly as possible. Looking at the amount of rework and maintenance activity that we had done for our scripts, it might have been a nightmare with some other scripting tool."
"We are satisfied with the support of Tricentis."
 

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."
"The Vision AI implementation works very slowly, affecting the speed of our work."
"The integration with mobile testing could be useful."
"The product is not very stable when used with cloud storage. It is very hard to load the screen, making it difficult to use the tool in cloud storage."
"The Test Management options are still weak - improvement is outlined, but not yet visible. I"
"I would like to see better integration with other testing tools."
"The solution is expensive."
"In Tosca, I see that there are no user guides."
"They need to improve on the reports after the execution of automation tests, since all the current organizations are looking for detailed graphical reports."
 

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 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 pricing and licensing of Tricentis Tosca were alright. Many customers look for end-to-end enterprise solutions, there were not many challenges with the pricing. However, the customers who are coming from Selenium or similar, feel they're paying a premium for this Tricentis Tosca license. If the right person is there for the implementation of the Tricentis Tosca, then it is one of the best tools in the market."
"The price of the tool is a problem for a lot of Brazilian clients or Latino clients, as it is expensive. Where I work, if one is low price and ten is high price, I rate the tool's price as a ten out of ten."
"They are probably more expensive than other comparable tools, but you also get the full suite of testing tools."
"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."
"We have around 200 [concurrent] licenses and the cost around $1.4 million a year."
"It is expensive."
"The tool is quite expensive."
