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 in testing processes sees improvement with multi-browser support and easier website interactions
Selenium HQ could improve by including a robust reporting framework, eliminating the need for external frameworks. The tool could simplify object identification, enabling users to generate XPaths without requiring detailed DOM understanding. Additionally, an automatic update mechanism for Selenium HQ would be beneficial, eliminating the need for manual downloads and updates of browser drivers when new versions are released.

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."
"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."
"All IBM testing tools are really well integrated."
"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."
"The cost of the license is better than other solutions; Selenium is a free, open-source tool and to date, we have not paid any additional fees."
"There is nothing I cannot do with Selenium."
"The main improvement is the lower cost of regression tests, where it may be about 30% more expensive in the first iteration but can save up to 40% or 50% in the next runs, and once the test scripts have been built, it is not necessary for the person executing the test processes to be an expert, allowing resources and costs to be optimized with lower costs in human talent and eliminating the barrier of functional knowledge."
"This is the most widely used tool throughout the world in this space, it has so much support available and is a benchmark for other tools."
"A lot of time and cost has been saved by using Selenium automation because now we don’t need all browsers to be tested by manual testers, as just one automation script is required which can be run across different browsers and we only need one person to kick off the script execution."
"While it isn't without faults, Selenium is probably the best and most versatile web testing tool available."
"The most valuable features are the ability to test and debug."
"We designed the Omani-channel automation framework, and achieved the maximum testing coverage includes localization (approximately 19), environment (web and mobile [iOS and Android]), and browser."
 

Cons

"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.

I like that, but the ability to edit the script is not as good as Parasoft or LoadRunner, which have C-Script."
"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."
"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."
"Selenium has been giving us failures sometimes. It is not working one hundred percent of the time when we are creating elements. They need to improve the stability of the solution."
"Whenever an object is changed or something is changed in the UI, then we have to refactor the code."
"I would like to see some reporting or test management tools."
"Selenium could offer better ways to record and create scripts. IDE is available, however, it can be improved."
"The most significant issue with Selenium is its difficulty in adapting to changing locators, which can hinder testing."
"An improvement to Selenium HQ would be the inclusion of a facility to work on Shadow DOM."
"They should leverage the tools for supporting Windows apps."
"Because Selenium HQ is open source, we don't have a customer service team or technical support, so we have to search on our own for answers."
 

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."
"Selenium is a free tool."
"This is an open-source product so there is no cost other than manpower."
"It is an open-source product, it is free for anyone to use."
"It is an open-source tool."
"The solution is open source."
"Currently, Selenium HQ is free for customers."
"It is free to use."
"The product is open-source and free."
