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

"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."

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

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

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

"It's pretty seamless with SAP and Salesforce because they've built in the field definitions and all the things that you need. You literally turn it on and execute your script and it records it. It's very simple. Then you can go back and put in some of the other functions. For example, instead of hard-coding field selections, you put in a data table so you can run it multiple times or with multiple data. It was actually written to work very well with SAP."

"Worksoft Certify is fundamentally a codeless automation tool, so everything is accessible."

"People focus on what they actually want to test and define it in a more detailed way. It shines a light on what they are testing, along with the speed and adaptability."

"The tool is easy to use. It is a drag and drop Microsoft type of solution."

"We found that Worksoft is easier to use because our business experts can do the tests. We didn't have to have IT experts."

"If we write a new test that's 80 percent the same as an existing test, it is pretty straightforward to reuse the steps from existing tests for our new tests and build upon them."

"In our estimation now, we save about 160 hours of manpower every month because we use Certify."

"For my team the most valuable feature of Certify is its flexibility and ability to include logic in the test steps."

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."

"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."

"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 would like the GUI to be more user-friendly and intuitive. We want to be able to move assets from project to another project without having to be in the same project or the same folder structure."

"The technical support comes on, and says, "Oh, so-and-so link is here, go through that link, and make the modifications." I'm not comfortable in making those changes. I want to schedule a call, share my screen, and have them fix it for me."

"The technical support has been good, but sometimes there are little delays. A lot of times when we need support, it's an emergency situation."

"We have had problems with an external cloud service (technology is Adobe Flex)."

"One feature that could be added to Capture 2.0 is generating a PDF file from your capture, so you can see your screenshots and steps."

"Sometimes we are facing crashes and downtime. Even our script will terminate in between the execution."

"Web automation can get a little better."

"Capture 2.0 is not as useful when you get into more mature automation."

More Worksoft Certify 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 typical range that we see is between 50 to 90 percent improvement in speed capabilities. Another aspect comes with the depth that they're able to test. It increases their capabilities overall to test at a broader level."

"The license cost is quite high. This might not be a consideration for a large company, but it will be for a small company. E.g., Tricentis (their competitor) offers certain exclusive use cases where a company can use it in a certain way, so this is another option that companies consider."

"It is costly. It is a bit more expensive than Tricentis Tosca and other tools. If they reduce its price going forward and have partnerships with other vendors, it will grow like anything."

"Cost-wise, compared with other tools, it is a great product."

"We save probably 50 percent of our time. The tool does what it's supposed to do, and we are able to actually work."

"I'm not aware of any licensing costs for Worksoft Certify."

"We would purchase more licenses right now if they were cheaper. Pricing is a little bit of a hindrance."

"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."
