RC
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 .

Venkata Yedida - PeerSpot reviewer
Good RESTful API support and performs well, but customization is difficult and time-consuming
My advice for anyone who is considering this product is that it is mainly for RESTful calls. If somebody is using Swagger APIs or some RESTful calls as part of the specification that they want to virtualize, then this tool can be a good choice. Also, if they want to virtualize a GUI tool, then it is good. In general, this is a good product but I think that the user experience has to be improved. There's just a lot of manual work that has to be done with scripting. This should be reduced to make it a more seamless experience for the user. I would rate this solution a seven out of ten.

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."
"As we have used most of the MQ stub, "MQ recording" is the most useful feature."
"Ties-in with the rest of the SoapUI platform and its ability to record traffic and create a virtual endpoint."
"ServiceV Pro enabled our organization to deliver an end-to-end solution by virtualizing external systems, which was easy to implement and provided for a lot of flexibility."
"The technical support is good."
"Features, such as using Groovy scripts for generating dynamic response, which read data out of Excel sheets and one-click deployment are really nice."
"Discovery option to create virtual services."
"In times of DevOps, where continuous delivery and deployment is progressing at such a fast pace, ServiceV Pro has emerged as an add-on for enhancing our API product finish."
"The solution is very easy to use."
 

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."
"It needs support for a wider set of protocols."
"The effort required to utilize the capabilities/usage of ServiceV Pro looks like the one area where we could have some further improvements"
"Requires more documentation or videos with examples, which is easily understood by the new users."
"ServiceV still has some bug in the tools, such as structure of the project, integration, and combination with different tools present."
"The solution does not allow you to export APIs to the cURL command like Postman."
"Greater capacity to create Virtual APIs based on HAR files or wireshark recordings."
 

Pricing and Cost Advice

"The product has a free trial available, which has saves on the initial investment costs."
"IBM RTVS is not that expensive compare to other giants, but it is still much ahead of some other tool having less features."
"Be updated with the latest offerings that the tool provides so as to avoid any clashes with issues, like licensing."
"Ability to have general IT staff enable developers using this software as opposed to more expensive vendors or developers building their own solution."
"Pricing is alright, however more options would be desirable for a fairly new product like ServiceV."
"This product is worth the cost."

Overview

Testing environments are often expensive and can have limited availability. IBM Rational Test Virtualization Server helps you shift testing to the left by removing dependencies on components that are unavailable or already in use. These components are simulated at the API layer, supporting a wide variety of technologies, allowing your team to test the riskiest elements earlier in the delivery lifecycle.

IBM

API virtualization in ServiceV Pro helps you deliver great APIs on time and under budget, and does so for a fraction of the cost typically associated with traditional enterprise service virtualization suites.
