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."
"I face no challenges or stability issues."
"Very user-friendly and the low code automation is really helpful."
"The tool's most valuable feature is Tosca Commander."
"With one click, it will scan all the elements on the screen, so that the user can select the required elements for automation tests."
"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."
"Tricentis Tosca is a really cool tool that you don't have to be technical to use it. Additionally, the solution is easy to use. The modules, libraries, and reusable are in an efficient way to update all the tests. I find it spot on with that. We also started using the design which we switched from Excel. The design was superior to Excel."
"The initial setup isn't too difficult."
"The Model-Based Test Automation is the most valuable feature, where you can create reusable components. Even though we are using a scriptless automation tool, there still needs to be an understanding of how to create reusable components and how to keep refactoring and how to keep regression, the test scripts, at an okay level. We are coupling Tosca with some other risk-based testing tools, as well, but automation is primarily what we're using Tosca for, the scriptless, model-based technology which is driving automation for us."
 

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 product needs to improve its pricing. It also needs to improve the infrastructure and DEX agent setup."
"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."
"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."
"Needs a UI to visualize the test case development."
"When using it with iOS devices, I cannot start automation directly and must use a remote machine."
"Primarily I'm dealing with customers looking for a cheap solution, and they are willing to try open-source automation solutions. So from this perspective, the price of Tosca is not as competitive."
"Tosca's reporting features could be better. Tricentis had a reporting tool called Analytics, but it didn't function properly after they reworked it. After that, they tried a new approach with key-tracing, and that didn't work."
"It can be quite expensive."
 

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."
"We have around 200 [concurrent] licenses and the cost around $1.4 million a year."
"The pricing is high, but altogether it offers you the ability to automate all sorts of applications: desktop, web, mobile, etc."
"It is expensive."
"There are two licenses: single user and multiple user. A multiple-user license means that several people can work together on one project and collaborate on code stored in a central location. A single-user license is for people working alone on a one particular application. It's much cheaper than a multi-user workspace. If you are getting a large volume of licenses for an enterprise, you can probably negotiate a discount, but I'm not sure about that."
"On a scale of one to ten, where one is very cheap and ten is very expensive, I rate the pricing a ten. The licensing model is based on a yearly basis."
"​It is an expensive tool compared to other test automation tools. It has a lot of advantages over other tools."
"We hired a consultant to figure out all the tools in our company and how they fit in our company before we purchased the solution."
"Licensing fees are paid on a yearly basis."
