Good reporting and interface, but supports limited types of protocols and requires low-level script editing

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.

Automation test development becomes accessible and effective for functional testers

Tricentis Tosca is a codeless tool, making it easy for everyone to understand the transition of how to develop scenarios or test cases. In Tricentis Tosca, analyzing failures is straightforward because every time it fails somewhere, I get the screenshot, which helps me analyze how and why it failed. It has all the modules, including some pre-built ones that can be reused efficiently. Compared to other code tools such as Selenium, where I used to develop one script in one day, with Tricentis Tosca I can easily develop one script in four hours or three hours, saving four to five hours in a day.

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."

"Using service virtualization, we are able to accelerate the testing and development activity."

"IBM Rational integrates the testing software as Rational Test Workbench, which is quite convenient and efficient as it is able to automate the test scripts."

"This solution provides for API testing, functional UI testing, performance testing, and service virtualization."

"I am impressed with the product's script test."

"The low code is the best feature."

"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."

"Object Identification Wizard."

"Scriptless SW QA automation provides a very quick on ramp to test automation with little maintenance."

"The model-based scriptless automation is the most valuable feature because it needs less maintenance as compared to script-based automation."

"The tool can be handled without any knowledge in parameterisation, especially the TestCaseDesign which makes the tool mighty and stable - even when releases in the tested software are subjected to deep code changes."

"The feature that I have found the most valuable is the recovery and cleanup process. Suppose there is a list of test cases and one test case has failed, it should not impact the other test cases. We can reuse the same test case. We can change the configuration of parameters and then use the test cases on the same thing. So, that's a useful thing. Otherwise, we have to use the cleanup process. Another useful feature is to have our own library files. We can create our objects in the libraries and reuse them. There is no need to create duplicate data for that. They have been giving some enhancements recently which means integration is also there. They've integrated with different software like Jenkins, Bamboo. So, we can also create pipeline points. They have recently given SAP and everything, which is very useful."

Cons

"Rational Performance Tester supports cloud technology in the version 8.7, playing test scripts back on the cloud is not stable."

"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."

"Implementing custom functions is bit tedious job, as ECMA script does not support some of the standard java-script functions, Also the Script editor window is not user friendly."

"Tricentis Tosca could improve on the ease of use. There is a steep learning curve. The reporting section could be better and some of the new features could be simplified. Additionally, the user management of the client and the server are confusing. There should not be two."

"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."

"The product needs to improve its pricing. It also needs to improve the infrastructure and DEX agent setup."

"Might have a learning curve, as it does not follow the traditional Record-Play functionality, but tests have to be built from requirements or Agile story cards."

"More and more artificial intelligence (AI) is coming in. So, some amount of AI to create natural language processing (NLP)-based test cases and manage defects would be very helpful. This is because the technologies have evolved in the last five to six months, so there is a potential opportunity there."

"It is quite difficult to integrate the solution with other tools."

"The tool lags in client-based applications. We have also encountered issues with the features in integrations."

"Tricentis Tosca’s technical support could be improved."

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."

"Tosca is expensive. I don't see small and medium customers going for it. It's always large enterprises that have a big pocket. It is very expensive as compared to the other tools that we have in the market. They should reduce the price by half, and if they do that, they would do better business. From the competition perspective, other solutions are at a pretty similar level. UiPath is also very expensive. One thing that I always wanted was a short-term consumption license. With Tricentis, the biggest challenge is that you have to go for a minimum of one year license, and they also try to sell you a three-year license. It would be good if people can get a three-month or four-month consumption license."

"Tricentis Tosca is an expensive tool and the licensing is not simple."

"The pricing is high, but altogether it offers you the ability to automate all sorts of applications: desktop, web, mobile, etc."

"Tricentis Tosca may be relatively on the higher side in terms of pricing, but their sales rep can give pretty decent deals when asked."

"There are different types of licenses: enterprise or professional. The cost varies."

"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 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 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."
