Using service virtualization, we are able to accelerate the testing and development activity
As per my working experience over the last three and half years with RIT/RTVS, I would consider the two following areas of improvement: * Reporting: In the recent release of RCPT, the "Usage graph" feature is included, but that still needs improvements in terms of UI and timeline filtering criteria. * Implementing custom functions is a bit of a tedious job, as ECMAscript does not support some of the standard JavaScript functions. Also, the Script editor window is not user-friendly .

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

"It has very easy and good validation techniques used for SWIFT, XSD, and WSDL validations."
"Indeed, I would recommend it; one major reason being that this product not only has a robust infrastructure implementation, it also has good technical support supporting standards from IBM."
"IBM RTVS has many useful features, but support for IBM MQ over this tool is unbeatable."
"It is very stable, rock-solid, and there is a possibility of about 20-32% cost savings."
"We have improved productivity about 90%."
"As we have used most of the MQ stub, "MQ recording" is the most useful feature."
"Tricentis Tosca has completely met our requirements."
"This solution allows you to create an entire automated framework where it allows you to easily manage everything in one place."
"We've found TBox to be valuable for scanning applications and automating test cases."
"Test case automation and ease of test case maintenance through Tosca has reduced the manpower needed for testing, reducing the time needed for testing, and has thus saved money."
"Tricentis Tosca is well integrated with other products like Jira."
"Overall the solution is easy to use compared to any other tools, it's very easy to organize and develop."
"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."
"The technical support is good, we were satisfied."

Cons

"Reporting: In the recent release of RCPT, the "Usage graph" feature is included, but that still needs improvements in terms of UI and timeline filtering criteria."
"User friendliness: I would rate it somewhere around 5/10 in terms of user-friendliness. It can be simpler to build stubs and middle-ware based test cases compared to the solution given by RTVS."
"One of the biggest disappointments for me and my team was dependency on various patches, or so call clients for every single technology."
"However, some peripheral features need vast improvement, namely the reporting and the dashboard areas."
"They need to move it to the cloud."
"Parallel execution is not yet implemented for Tosca. This means you can't execute the same test case on multiple machines remotely."
"It is quite difficult to integrate the solution with other tools."
"I would like to see better integration with other testing tools."
"Browser compatibility (probably solved in the newest versions). Version 8 of Tosca had weak compatibility with automation via browsers."
"They need to improve on the reports after the execution of automation tests, since all the current organizations are looking for detailed graphical reports."
"While the initial setup was straightforward, we required assistance with the configuration to ensure that everything was done correctly."
"A disadvantage of Tricentis Tosca is that you have to customize it according to your need, during the early stages of the software, particularly during upstream testing, before system and unit testing."
"Not part of my job, but during the upgrade our IT departmend faced several issues in the installation process of the new version."

Pricing and Cost Advice

"IBM RTVS is not that expensive compare to other giants, but it is still much ahead of some other tool having less features."
"The product has a free trial available, which has saves on the initial investment costs."
"In terms of the licensing costs for Tricentis Tosca, we are spending more or less $70,000 per year. We have a very complex mechanism because there are some business users and some BI users, so the licensing structure is not simple, but support is included."
"It is expensive. There is also the training cost, but it does speed up the process. So, you get a return on investment."
"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."
"The pricing of the solution comes as part of our Tosca bundle."
"Tricentis Tosca should improve its pricing. It is expensive."
"I am satisfied with the cost."
"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."
"Tricentis Tosca is an expensive solution and there is an annual license required. The whole licensing process is confusing and it could be made easier."
