Good reporting and interface, but supports limited types of protocols and requires low-level script editing

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.

Automation has delivered strong ROI with AI-driven test prioritization and parallel reporting

The best feature of Worksoft Certify is the automatic report generation. Unlike traditional tools like Selenium or Java-based frameworks where reporting often requires custom coding, Certify handles this natively. We are currently utilizing the 14.5 version, which has modernized these capabilities, though we frequently manage backward compatibility for clients still running on the 12.x version series.

Quotes from Members

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

Pros

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

"Using service virtualization, we are able to accelerate the testing and development activity."

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

"All IBM testing tools are really well integrated."

"IBM Rational integrates the testing software as Rational Test Workbench, which is quite convenient and efficient as it is able to automate the test scripts."

"This solution has enabled us to automate in order to tremendously save time."

"It is a lot easier to maintain test scripts on Worksoft Certify than on other testing tools that we have had in the past."

"One of the bigger value-adds that we had was extracting data from our warning systems to be inputted into our new learning system."

"The solution has cut our clients' test maintenance time for changes, like patches or system upgrades; they used to take a lot of time until the production validation completed, and now it is just seconds until it is ready, so they can do executions within a couple of minutes."

"A specific feature that I found to be the most valuable in the solution for our company's work processes stems from the fact that it is useful as a low-code automation tool."

"We are mainly using it for the SAP application, and for the SAP application, if you don't have any experience with automation tools, after a few training sessions, you can easily automate the scripts."

"Automation using Worksoft Certify has saved our testing times by 40% to 50%."

"Worksoft is a good tool to start with as it is a codeless tool."

More Worksoft Certify pros

Cons

"Rational Performance Tester supports cloud technology in the version 8.7, playing test scripts back on the cloud is not stable."

"Implementing custom functions is bit tedious job, as ECMA script does not support some of the standard java-script functions, Also the Script editor window is not user friendly."

"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."

"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.

I like that, but the ability to edit the script is not as good as Parasoft or LoadRunner, which have C-Script."

"When it is unstable, there will be times when a test that we are running in Certify will just stop, and it will say, "Aborted." There will be errors. There will be no explanation as to why it happens. It has now happened maybe one out of 20 times. When it happens, I just tell our QA team to stop Certify and restart it, hoping we don't see it again."

"If we can import process from other automation tools like UiPath, Selenium, or Automation Anywhere, then it would be more helpful."

"In my opinion, that whole module of permissions is very confusing and lends itself to common errors."

"When automating procedures in web applications with Worksoft Certify, we mostly face object and Windows issues. It would be better if Worksoft Certify fixes this issue."

"Right now, Capture 2.0 doesn't really work for our Business Analysts."

"I know that we did do some automation, what we call "bots," with Worksoft, and it was clunkier than some of the RPA tools that are currently on the market."

"Web automation can get a little better."

"Worksoft Certify needs a bit of improvement for its web-based processes. It can be difficult because you need to recall the maps, then you still have to add-on for your browser. When you are using the browser-based testing, you cannot even move your mouse or do anything on your system when you are using the web-based testing. Therefore, it needs a bit of improvement on that side. While it does work, it needs improvement. From the SAP side, there is nothing better than Worksoft Certify. However, from the web-based, we are moving towards Fiori. SAP will soon be totally web-based. For Fiori, they need to be great with SAP testing. Thus, Worksoft has to improve the web-based testing part for Certify."

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."

"I think they came out with a different type of licensing specifically for testing. Therefore, you don't have to use a more expensive user license, you can use an automation license. So potentially, if we had 100 use cases, we could spin up a 100 different machines, have them all run and be done in five minutes. That would be the goal, but I don't know if that would actually succeed or not."

"Our ROI is primarily a reduction in testing time. The testing, when we were doing it manually, was 30 to 40 percent of the project's cost."

"The initial upfront cost in terms of licenses, plus all the money that we spent developing tests, has proven it's worth. Now, we can do a regression test suite in ten days as opposed to sixteen weeks."

"Saving money and better quality, these are the benefits of Certify."

"We could use Certify to do robotic process automation, which is basically running a process on your correction system instead of your test system. Therefore, we may do that in the future."

"I don't have much idea about the pricing, but it is a licensed tool, and it is somewhat costly."

"On our last big SAP implementation project, we inserted an automation resource into the beginning of the project. Between automating regression processes, data staging, and using our automation to help repair cutover and conversion issues. We saved the project about $1,700,000."

"We ended up buying too many licenses. They were very good at selling it to us, and probably oversold it a little. We bought 45 licenses and have never used more than twenty. However, they gave us a pretty significant discount on the bigger license, so it made sense for us to buy enough that we wouldn't have to go back and ask for more."
