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 .

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."

"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."

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

"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."

"Compared to other tools we have been looking at, you don't have to be a programmer to operate it, though it helps, and it is also a product that can be used by business people."

"Good use in Agile workshops, where the person needs to conceptualize the tests before the developer provides the complete application interface."

"It is easy to maintain and easy to automate, no coding skills are required to automate, and it is also easy in terms of transferring knowledge and skills."

"As a codeless automation tool, the product offers a user-friendly experience without requiring extensive coding knowledge. Users can easily handle various applications, including web applications, SAP applications, Windows applications, and even Salesforce applications, without manual coding."

"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."

"I would recommend this solution to others."

"I liked the "no required scripting" part as most of the people in my team are not skilled QAs and half of the team reside offshore, thus it suited to most of our requirements."

"We've found TBox to be valuable for scanning applications and automating test cases."

Cons

"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."

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

"They need to move it to the cloud."

"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."

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

"The integration with mobile testing could be useful."

"Tricentis Tosca's performance could be better. Sometimes when we are remapping or when it is loading it can take a lot of time. There are free solutions that have better performance in this area."

"What needs to be improved in Tricentis Tosca is its centralized repository mechanism because it's not as flexible. The repository in the solution where you store the data and the script for test automation is quite an old-fashioned mechanism that could be improved."

"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."

"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."

"Some issues with stability, but those are minor errors."

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."

"Pricing for Tricentis Tosca could be improved because it's very expensive."

"The tool is quite expensive."

"The tool's pricing is lower than that of other automation tools."

"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 is an annual cost for Tricentis."

"I would rate the pricing a seven out of ten, where one is cheap, and ten is expensive. It is on the higher side."

"We have around 200 [concurrent] licenses and the cost around $1.4 million a year."

"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."
