IT Analyst at Tata Consultancy Services

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 .

Senior engineer at Nagarro

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

"As we have used most of the MQ stub, "MQ recording" is the most useful feature."

"We have improved productivity about 90%."

"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."

"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."

"The most valuable feature of Tricentis Tosca is the Tosca Commander. Functionality is another thing I find most valuable in the solution."

"One feature we like is the live connectivity of the product, in other words, you can push transactions through to live, and you can intercept some transactions and return them back with mocked data."

"This is a complete Test Automation solution of our Enterprise Legacy system, which has many technical peripherals."

"It has allowed us to have a highly reusable Regression Test suite."

"The most valuable feature of Tricentis Tosca is it is a completely scriptless automation tool, which I liked a lot. They keep on continuously improving their tools, wherever we are facing any challenges they are able to provide a solution for it. It is easy to learn, everyone can easily read and understand what is happening with the scripts. Any business user or function tester can use the tool efficiently. This is a complete solution package."

"The product helps us to create very accurate test cases."

"Tricentis Tosca has completely met our requirements."

"TOSCA Testsuite is a very good automation tool."

Cons

"They need to move it to the cloud."

"However, some peripheral features need vast improvement, namely the reporting and the dashboard areas."

"One of the biggest disappointments for me and my team was dependency on various patches, or so call clients for every single technology."

"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."

"The main area where there is room for improvement is how they do upgrades."

"Getting support from their support team is very difficult; the overall competence of the support has declined, and it's taking a lot of time to get solutions."

"With regard to areas of improvement, report customization should be easier. It would be good if Tosca could provide standard reports for at least 20 variants. At present, there are only three to four variants. The mobile engine needs to be faster and easier to use; it is a bit cumbersome. Also, the object identification in the mobile engine needs improvement. I would like to see easy-to-use customizations for reports in the next release."

"There have been some setbacks because of upgrades."

"The initial setup was complex."

"Scaling can be tedious."

"It can be quite expensive."

"The stability and reliability of Tricentis Tosca is just 60% for me."

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."

"A competitor of Tricentis Tosca: Katalon Studio, is very similar and offers lower pricing, though Tricentis Tosca offers more features and benefits."

"My understanding is that it's an expensive product, although I don't know the specifics with regards to pricing."

"It is an expensive tool compared to other test automation tools. It has a lot of advantages over other tools."

"I'm not sure if I'm at liberty to talk about the pricing, but it has some significant costs. For example, you have to pay a license and maintenance fee. Then the rest of the terms are negotiable. We have to consider what we need and what benefit we get from it."

"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."

"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 of the solution comes as part of our Tosca bundle."

"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."
