Executive SummaryUpdated on Dec 15, 2024

IBM Rational Test Workbench and Qt Squish compete in software testing solutions, with Qt Squish often having the upper hand due to its strong GUI testing features and cost-effectiveness.

Features: IBM Rational Test Workbench stands out with its powerful integration options, which include a broad range of testing capabilities beyond GUI, and its flexibility to configure testing environments. It excels in API testing, functional UI testing, and service virtualization. Qt Squish offers rich GUI automated testing with script recording that supports various scripting languages. It provides excellent object identification tools and supports cross-platform testing, including mobile and embedded platforms.

Room for Improvement: IBM Rational Test Workbench could enhance its usability for GUI-centric projects and reduce its high initial setup cost. Expanding its scripting language support could increase its adaptability for different development environments. Qt Squish could improve its documentation further and provide more seamless support for non-GUI related testing and broader integration with other development tools. Enhancements in reporting capabilities could also be beneficial for more complex testing scenarios.

Ease of Deployment and Customer Service: Rational Test Workbench offers a straightforward deployment process with extensive documentation, making it accessible for larger teams. Its technical support is comprehensive due to its well-established integration within the IBM suite. Qt Squish provides a specialized deployment model focusing on GUI testing, with personalized support thanks to its alignment with Froglogic's direct designer interaction, facilitating quicker troubleshooting within its niche domain.

Pricing and ROI: IBM Rational Test Workbench tends to involve a higher setup cost due to its extensive feature set but provides significant ROI, especially for large enterprises with diverse testing needs. Qt Squish offers a more cost-effective initial setup aimed at quicker ROI for projects more focused on GUI testing, making it an attractive option for companies prioritizing efficient GUI test automation.

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.

Testing solution supports Java testing with good reliability

There is nothing you can do for almost every application. If you do it for a single version, it is rather easy. However, if you want to run it for different versions of the software, then you need the Qt version of Java. You need to set up some special environment variables to be able to do that.

Quotes from Members

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

Pros

"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."

"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."

"I can perform Java SWT."

"The most important part is that it allows me to create black box tests faster and easier."

"Powerful and intuitive Integrated Development Environment (IDE) - I use this IDE daily for creating new tests, debugging tests and running tests."

"The biggest ROI is the time that we got back from our QA team because they didn’t have to manually regression test our product every release."

"Now we have completely automated the Squish runs using CI tools and Squish is not at all getting stuck or creating any problem."

"Squish data-driven testing is very powerful and we can easily check for bulk and huge data without any issues."

"I find it very user-friendly and easy to start working with. The main benefit for me is that it allows testing applications developed in the Qt language. This capability makes Squish a game-changer, as it's the only tool I've found that enables automation for applications written in Qt. I appreciate three main aspects. Firstly, the documentation is excellent. Secondly, I value the way the tool efficiently locates elements during testing. These are the two aspects I particularly like."

"It is very stable."

Cons

"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."

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

"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."

"Features like recovery scenarios can be added as an improvement Reporting can be improved."

"It still requires better solutions for object identification and an enhancement to identify all the objects of the AUT before building the object map."

"There had been a lot of improvements with froglogic Squish already. There were some scenarios in which this particular solution was available in different flavors. They have pulled everything together in one solution. There were some monitoring systems, which were missing out from the solution earlier. They have a centralized dashboard for monitoring the test cases and their execution. It's a full-blown solution, there are not many glitches in terms of something missing out of the package."

"The platform could be improved by implementing some basic functionalities that are frequently used, such as login procedures and screen handling when multiple screens are used at the workplace."

"Sometimes, I had problems, but their support team resolved almost of them in short time."

"The only criticism I have is the IDE needed a bit of polish in version 5.2 (this may have been fixed in the latest versions)."

"You need to set up some special environment variables."

"The price could be better."

More Qt Squish cons

Pricing and Cost Advice

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

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

"The price could be better. I believe each developer license costs about 6000 or 7000 Euros per year."

"It is expensive."

"The platform is highly-priced."
