Easy to set up and scale but needs more data virtualization capabilities
I'm working with a service organization and I'm working for a client and that client requires this solution. That's why we use it. Basically, we are just a customer and end-user. The solution is easy to set up and a good tool for the service virtualization so far. I'd rate the solution at a seven out of ten. If the product could do more things, I'd give it higher marks.

End-to-end regression automation has accelerated delivery and now secures complex test data
I think Tosca can be improved, particularly in AI capabilities because right now Tosca does not have any strong API capabilities. It has some AI features in the newer version, but many organizations have not adopted these due to version-specific problems, as some are still using older versions. From an AI point of view, they can enhance reliability since the world is moving towards AI, and every tool must be integrated. While Tosca has made attempts, I have not used them and they are not widely adopted, so they are stuck in the testing phase in my organization. I would also mention that while I am currently using Tosca Mobile, the loading part and connectivity issues need improvement. They should better integrate AI features that are already present but not widely used across many organizations. Reliability on the AI aspect needs enhancement for practical application. From the perspective of governance and security, I believe Tosca can develop its own LLM or leverage third-party LLMs while maintaining security and risk management regarding client data. Many companies prefer using Tosca due to data security, which is crucial. An in-house LLM could significantly enhance its debugging power and provide helpful solutions upon test case failure.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"Using Virtualize, this dependency has been removed completely, allowing the test team to provision many more orders in shorter time, enabling them to test much more, much faster."
"The solution is easy to set up and a good tool for the service virtualization so far."
"Parasoft Virtualize helped us in accelerating application delivery by allowing us to test early."
"Easy testing environment creation. No need to have deep development/infrastructure knowledge."
"We decided to use the Parasoft solution because it's more powerful and very easy to use."
"Parasoft's product is easier to operate, and drives the user to make the right decisions and complete the work efficiently."
"Parasoft Virtualization allowed us to create a simulated environment and test the code before entering the testing cycle."
"We now have the ability to test our complex applications completely detached from integration middleware, which improves the reliability, speed, cost, and simplicity of testing."
"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."
"TOSCA Testsuite is a very good automation tool."
"We switched to Tosca because it's a no-code solution, so people without coding skills can also use it, and if you have an in-depth understanding of the Tosca framework, you can easily automate any complex application."
"Customer Service: Best I have ever seen. Technical Support: Best I have ever seen."
"It's a simple tool, particularly in terms of system testing. You can also convert and automate using Tricentis Tosca with ease."
"The use of automation is most valuable."
"It allows manual testers to pick up automation, because it is a scriptless tool."
"Overall, everything is reusable simply via drag and drop, and you will always have a single point of maintenance (e.g. in a future release of your SUT a button was added, you just need adapt the module. Linked test cases and execution lists are updated automatically)."
 

Cons

"It would be ideal if the product offered more in terms of data virtualization or have a separate product that could be combined with this one that could offer a bit more in order to cover more of our requirements."
"When Virtualize is running on a (virtual) machine with limited memory, over time it might consume more and more memory and (worst case) stall."
"JMS Queue Monitoring: When deploying the TIBCO JMS monitor, we saw an approximately 50% failure rate in detecting the desired event."
"It is somewhat complex regarding its configuration setup with different technologies."
"This product is too expensive when scaling."
"Performance enhancement for large payloads."
"Only about the memory, if you don't meet the minimum RAM required, performance is not stable."
"It should have more fine-grained authorization."
"Sometimes new features do not work as shown on slides, in the first release."
"It can be quite expensive."
"I think the new version is not so stable, and that’s what's stopping us from moving over to it."
"Do not buy this tool if you simply need a driver for your automation, as open source solutions (e.g. Selenium), or technology specific solutions are more suitable here."
"The solution should work to try to lessen the cost of the solution. Right now, using it is costly for companies such as ours."
"At the time I was using the product, the reporting function was lacking in usability and detail."
"The solution should work with the Linux platform. Right now, it only runs on Windows."
"Tricentis Tosca’s technical support could be improved."
 

Pricing and Cost Advice

Information not available
"They are probably more expensive than other comparable tools, but you also get the full suite of testing tools."
"The tool is quite expensive."
"​It is an expensive tool compared to other test automation tools. It has a lot of advantages over other tools."
"The pricing is high, but altogether it offers you the ability to automate all sorts of applications: desktop, web, mobile, etc."
"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."
"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."
"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."
