CEO at Xcelliti

Good integration with other tools, stable, scales easily

There are a number of things that they can do to simplify the tools, but the most important thing that they need to do is simplify the installation. This includes the workbench as well as the other tools. In the future, I would like to see the other types of tests supported, that are not already covered in the DevOps approach. This would include, for example, penetration testing.

Nghiêm Phương

CEO at SMOne

Quality and security improvements drive user satisfaction

We have many customers, but with Parasoft SOAtest, we just focus on .NET, Java, and PHP protocols and message formats. For deployment, it runs on-premise with Parasoft SOAtest. The transition from manual testing can be challenging, and it's the first time they're using automation testing with Parasoft SOAtest. For the tool itself, Parasoft SOAtest, I would rate it as great with an overall rating of 10 out of 10.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:

Pros

"Reporting is pretty good. Its interface is also good. I'm overall pretty happy with the functionality and use of IBM Rational Test Workbench."

"This solution provides for API testing, functional UI testing, performance testing, and service virtualization."

"Parasoft SOAtest has improved the quality of our automated web services, which can be easily implemented through service chaining and service virtualization."

"One of the most valuable features I found in Parasoft SOAtest is its ability to extend the product."

"If you want something that’s not provided out of the box, then you can write it yourself and integrate it with SOAtest."

"They have a feature where they can record traffic and create tests on the report traffic."

"We do a lot of web services testing and REST services testing. That is the focus of this product."

"Technical support is helpful."

"The solution is scalable."

"Generating new messages, based on the existing .EDN and .XML messages, is a crucial part or the testing project that I’m currently in."

Cons

"There are a number of things that they can do to simplify the tools, but the most important thing that they need to do is simplify the installation."

"It should have more interfaces. In terms of interfaces or protocols, what you can do with Rational is far limited as compared to other products out there. What it does, it does great, but it only gives you limited types of protocols. It supports between 8 to 15 types of protocols, whereas other test tools give you 20 to 30 types of protocols with which you can do testing and convert to script. It records Javascript-based scripts, and you got to know a little bit of Java to basically be able to edit them, but the level of editing you got to do is very low. I like that, but the ability to edit the script is not as good as Parasoft or LoadRunner, which have C-Script."

"During the process of working with SOAtest and building test cases, the .TST files will grow. A negative side effect is that saving your changes takes more time."

"Enabling/disabling an optional element of an XML request is only possible if a data source (e.g., Excel sheet) is connected to the test. Otherwise, the option is not available at all in the drop-down menu."

"The summary reports could be improved."

"Reporting facilities can be better."

"The performance could be a bit better."

"The feedback that we received from the DevOps of our organization was that the tool was a little heavy from the transformation perspective."

"Compatibility with HTTP 1.1 and TLS 1.2 needs to be improved."

"UI testing should be more in-depth."

More Parasoft SOAtest cons

Pricing and Cost Advice

"The pricing is a little bit on the higher side, although it is really good."

"It doesn't really concern me. Licensing is on a yearly basis."

"The license price is a little expensive, but it provides a better outcome in terms of the end-to-end automation process."

"From what I understand, Parasoft SOAtest isn't the cheapest option. But it has a lot to offer."

"We are completed satisfied with Parasoft SOAtest. The ROI is more than 95%."

"They do have a confusing licensing structure."

"The cost of Parasoft seems to have gotten higher with a projection that wasn't really stipulated for our company. They've done a tremendous job at negotiating those deals."

"It is an expensive product, so think carefully about whether it fits your purposes and is the right tool for you."

"I think it would be a great step to decrease the price of the licenses."

"The price is around $5,000 USD."
