We primarily use the solution for API virtualization.
The solution has a lot of great features that we are able to take advantage of.
The initial setup is quite easy to manage.
The stability is good.
We've found the scalability to be very good.
We've only recently started using the solution. it's been about three months or so. It hasn't been that long just yet.
The stability so far has been very reliable. There are no bugs or glitches. It doesn't crash or freeze. The performance is great overall.
The solution can scale. If a company needs to expand it, it can do so. It's good.
We have not yet contacted technical support. We haven't used the solution for very long and haven't come across any difficulties just yet. Therefore, I can't speak to how helpful or responsive they are.
We did not find the initial setup to be difficult. It's not a complex process. It's largely straightforward and simple. An organization shouldn't have any trouble with it.
We have our own team of five engineers that can handle deployment and maintenance.
We handled the deployment ourselves. We didn't need a consultant or integrator to assist us.
The pricing of the product is fair. It's not unreasonable by any means.
I'm working with a service organization and I'm working for a client and that client requires this solution. That's why we use it. Basically, we are just a customer and end-user.
The solution is easy to set up and a good tool for the service virtualization so far.
I'd rate the solution at a seven out of ten. If the product could do more things, I'd give it higher marks.
We now have the ability to test our complex applications completely detached from integration middleware. This improves the reliability, speed, cost, and simplicity of testing.
MessageQueue support: Our infrastructure was designed with the ability to detach client systems via MessageQueue queue managers.
JMS Queue Monitoring: When deploying the TIBCO JMS monitor, we saw an approximately 50% failure rate in detecting the desired event. This is probably due to the asynchronous nature of the event itself, and the natural background flow of other events. Though this feature sounds cool, we had to work around it and create a different solution.
I have been using it for three years. I am currently using Parasoft Virtualize 9.10 and Parasoft SOAtest 9.10.
Initially, we had some stability issues due to the fact that we were loading an entire day’s traffic at once. We were able to resolve these issues with Java heap monitoring and tuning.
We had no scalability problems. The virtualized solution is high performance.
Technical support is 9/10, top notch. Parasoft support turnaround is quick, and attentive. They will work through an issue with you to see it reproduced and get back to you with a workaround or future fix.
We did not have a previous solution.
The setup was relatively straightforward, with just a couple quick clarifications to understand the relationship between configuring Development Testing Platform, SOAtest, Virtualize and Environment Manager.
Cloud is the future. Evaluate cloud licensing up front so you don’t have to repurchase new licenses when your company finally lands in the cloud.
We evaluated CA Service Virtualization and IBM Green Hat.
Most folks go in thinking small, which is a good start. However, once you have learned the capabilities of the tool, think big for the best solutions.

Captures and simulates live system behavior from recordings.
- Dependency Removal
- Not yet completed
- Controlled by a third-party or partner
- Available for testing only in limited capacity or at inconvenient times
- Needed for simultaneous access by different teams with varied test data setup and other requirements
Service Virtualization has provided a way to move forward where we do not find any way to go. Parasoft Virtualization has provided that feature or way, by creating virtual assets and implementing or achieving the real atmosphere through a Virtual Channel.
It captures and simulates live system behavior from recordings.
Virtualizing a component or service which does not exist or is under development.
- Broad, flexible support for literal, XML, JSON requests & responses
- Broad, flexible support for Protocol (HTTP, HTTPS, JMS, MQ & for other traffic types such as SQL Queries), Transport & Message Formats (i.e. EDI messages)
- Ability to create data driven responders
- Recording traffic by acting as a proxy and replaying the recorded traffic for quick and easy virtual asset creation.
- Virtualize fills the gap by providing access to their behavior by removing dependency of databases, mainframes, third-party systems, etc.
- No Limitations on Traffic hits per day.
There is not much more room in areas of improvement, unlike a Portal-based Virtualization.
I didn't see any updates coming in next releases. Except, sometime we face proxy exception issues, which is already reported to Supported Team.
Overall, It's trusted and working nice as expected.
No. I did not face any issues regarding stability.
No. I did not face any issues regarding scalability.
Customer Service:
As it is a commercial tool, the customer service is good as compared to other tools. I will be assisting the Parasoft Support team soon based on its complexity.
Technical Support:
No doubt, it is good and up to the mark on technical side.
Regarding CI/CD, I have implemented the nightly build jobs through Jenkins, but also through Parasoft Continuous Testing Platform (CTP), where we can implement directly. We implemented the same and also integrated multiple scripts through grouping in Parasoft CTP.
It is somewhat complex regarding its configuration setup with different technologies.
I am working from one of the prestigious client and regarding the level of expertise, they are much better equipped with sound knowledge.
It is good, but it also depends on your requirements/strategy.
Advice to others on Parasoft Virtualization is that it is a good tool to be used for Service Virtualization as compared to other tools in the industry.
I have done some basic R&D and also compared it. I find suitable as per user requirements and easy handle of virtual assets.
If you're looking for Service Virtualization, you can go ahead and use Parasoft Virtualization - Community Edition (Free Edition) with basic features.
I’m a frequent user of Parasoft products, amongst those products is Virtualize. Virtualize is a tool that enables me to create virtualized services. In my case, most of these have been webservices. Virtualize isn’t limited to webservices only as it supports other kind of services as well. One of the best features of Virtualize (and all Parasoft products) is that it is very open. Meaning that if the feature you seek isn’t supported out of the box, the Eclipse IDE most of the time will have a solution available for you. If this isn't available either, there is always the open API which can be used to build in your own solution. This allows you to alter the tool specific for your needs.
At this moment Virtualize is able to be used in a Continuous Delivery environment. Service Virtualization enables agile teams to start more early and shorten the time to market, combined with a Continuous Delivery solution it enhances this strength. Therefore, in my opinion this is one of the best advantages for Virtualize. Other great advantages are:
There is one big disadvantage in my opinion:
Disclosure: This review is a personal view on the product and is independent from my employer.
Its business model of perpetual licensing sales is outdated; they should deliver it as SaaS.
I have been using it for three years.
I have not encountered any remarkable deployment issues.
I have not encountered any remarkable stability issues.
This product is too expensive when scaling.
Customer service is 6/10.
Technical Support:Technical support is 6/10.
I did not previously use a different solution.
Initial setup was straightforward.
A vendor team implemented. Their level of expertise was 8/10.
It’s difficult to provide ROI information, because it depends on the costumer and how it uses the product. With this product, it probably takes at least six months to see ROI (vendor says 3 weeks).
The vendor sells perpetual licenses; could use SaaS. Price is kind of high, but that’s normal because it’s a new, trending solution.
Before choosing this product, we evaluated it against CA and IBM solutions.
No remarkable advice; solution is really useful and should be adopted if the budget allows it.
It should have more fine-grained authorization. The authorization is currently role-based, i.e., what one can do.
In addition to that, data-based authorization (with what virtualized services) would be very useful in an environment where multiple teams are using the product.
I have used this solution for about five years.
The product is running with minor support; stability is not an issue.
In the former version, there were some scalability issues but these were resolved rapidly.
The technical support is very good, with short lines and short response times from well-skilled technical employees.
Initially, we were using embedded applications using in-house built solutions. This was well-fitted for unit testing but the higher-level functional testing was difficult. The performance testing needs service providers communicating over the same protocols.
You should calculate what you need.
Start with the Community Edition which is available. Define your needs first and calculate the benefits.
There are several features of Parasoft Virualize worth mentioning, but some of them are:
1. Ease of creating message responders
2. Using custom transports, message formats and tools
3. Working with message proxies
4. Customizing request matching and correlations
Parasoft Virtualize helped us in accelerating application delivery by allowing us to test early. We were given an application under test when some of the major back-end components were not available, apart from the service contracts being ready. Using SV allowed us to expose defects when they were fastest, easiest and least costly to resolve. We were able to complete system testing, and resolve interface integration issues even before the real back-end system was made available. Our organisation was able to shift left using Parasoft Virtualize.
Performance enhancement for large payloads.

None
The technical support is very good.
The initial set up for Parasoft Virtualize is very straightforward. All the latest updates are available on the web site and a great user guide to help through the installation.
With respect to ROI, the factor worth mentioning is that we found more than 500 defects as a part of early testing. It saved good money, if these were identified in later stages, identified loopholes early and allowed to test scenarios which otherwise would be impossible to test in an integrated environment.
Reports about status of test environments.
I've been a Parasoft Virtualize user for the past 3 years.
No, installation is very friendly.
Only about the memory, if you don't meet the minimum RAM required, performance is not stable.
No
Excellent.
Technical Support:Very good
I tested tools from other vendors. We decided to use the Parasoft solution because it's more powerful and very easy to use.
It's very friendly. It takes minutes to install the tools and start to use. The interface is Eclipse based, so some people it can be familiar. Anyways, if you are not a very technical person you will found the interface easy to understand.
Parasoft have a lot of information on their website. This is valuable information because the majority is based on real customer information. You can consult case studies and reports about benefits of service virtualization solution, even if you are already involved in service virtualization you can review this information about best practices.
Please feel free to contact me if you want to hear more about Service Virtualization and how this is related with SDLC in order to meet solutions as Continuos delivery, Continuos Integration and Continuos Testing.
1. Ease of creating working bank-end web services
2. Ability to customize individual responses
3. Minimum knowledge required for setup
4. Always ON-LINE
Parasoft Virtualization allowed us to create a simulated environment and test the code before entering the testing cycle. Also, increase testing cycles without impacting any major line of business and back-end components. Furthermore, it provide us with an environment that is always available for QA, Automation, and Performance.
An area of improvements would be Data Repository, as in current stage it is difficult to manage data from this aspect. Searching, modifying and updating data is a tedious task. In addition, importing to the repository function is

Yes we have evaluated Selenium.
Quick generation of virtual assets from service definitions such as WSDL documents
Extend the basic functionality of virtual assets using scripting
Environment Manager providing a clear user interface for environment provisioning and configuration
Docker image available for seamless Continuous Delivery and Continuous Testing integration
I have used Virtualize in two projects now, and in both projects it has delivered impressive results.
Even though improvements are being made in this area with the developments around Data Repositories, I am still missing the opportunity to easily store and reuse data persistently, without having to redeploy the virtual assets after each update.
Real life example: when a student registers for a course, this affects his or her tuition situation. For each student, all registrations need to be stored somewhere because at any moment in the future, the current tuition situation needs to be derived using all current and past course registrations.
At the moment, I am working around this by adding scripts (Extension Tools) that store the data required in a database separately from Virtualize and retrieve this when necessary.
A generic solution for this issue that would at least reduce the amount of scripting necessary to properly simulate real life behavior would be very welcome.
I have been a Parasoft Virtualize user for the past three years.
No. Since Virtualize is provided either as a simple installer or as a Docker image (in the most recent versions), installation is as simple as clicking a button.
When Virtualize is running on a (virtual) machine with limited memory, over time it might consume more and more memory and (worst case) stall. This is probably more of an Eclipse issue than purely a Virtualize issue, though.
No.
Excellent.
Technical Support:Great. Whenever I have any questions concerning Virtualize, there's always someone available to help.
No, this is the first service virtualization solution I have used. I do have previous experience using simpler stubbing solutions, but these do not provide the flexibility and ease of use that Virtualize does.
Very straightforward. Installation is a matter of minutes, after which you are set to build your first virtual assets, either by recording live traffic or modeling them using predefined service or message specifications.
As a freelancer, I am hired by end users to implement Parasoft solutions on site. As such, I work very closely with the Parasoft team, but I am not part of a vendor team, nor do I work somewhere in-house.
Yes, there is an initial investment requirement, and you should definitely do some research to see whether this investment pays off in terms of increased speed of delivery or test coverage.
However, please take into account that the ease of creating, deploying and especially maintaining and managing complex virtual assets using Virtualize could very well turn out to be more cost-efficient in the longer term compared to building and managing custom solutions.
No, as I was (part of) the implementation team, not the person responsible for product selection and buying.
Additional information, presentations and case studies regarding Parasoft Virtualize, its features and the proven benefits it has provided to a range of Parasoft customers are readily available. Contact your regional sales partner, they are there to help.
