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.

Provides real-time application monitoring, but the technical support services need improvement
They could improve the platform's customer support services. Many users, including myself, have experienced significant delays in response times and unsatisfactory resolutions when reaching out for assistance. The support team often provides generic recommendations that do not address the specific issues raised, leading to prolonged downtime. Additionally, there needs to be more proactive communication and follow-up on reported problems. Another area for improvement is keeping pace with updates to the latest libraries and technologies. For example, Sauce Labs' proprietary driver and Saucectl need to be updated more frequently to support the latest versions of popular testing frameworks like Playwright. This lag in compatibility means that users may miss out on critical features and improvements available in newer versions, necessitating workarounds or compromises in their testing workflows.

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."
"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."
"Since this is an all-in-one testing site, we are able to take advantage of the browser OS combinations, mobile emulators and simulators, and real mobile devices. This is important to us since we have a variety of users, browsers, OS, etc."
"The combination of OS platforms, platform versions, browsers and browser versions support on VMs."
"The ROI is 100%."
"Testing subscription videos for on-demand software, making them better quality and bug free for our customers."
"APPIUM for mobile testing has improved our organization by allowing us to test our website on more devices and browsers than we currently possess."
"With only a few clicks, it gives us the availability to use any browser and OS combination whenever we want."
"Sauce Lab analytics helped us to get detailed knowledge on test cases execution and logs."
"It provides zero maintenance browser instances."
 

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."
"Sometimes pasting text while using "text object" does not seem to work, and it slows down testing times quite a bit."
"The only drawback is the speed, it will be good if we have a server in Asia too. It will be great if we can improve speed while initialization and execution."
"The session duration is too short; it's only about 3 hours long."
"We have had some issues with the Sauce Connect Proxy on our Jenkins servers failing to start, which makes the optimal CI/CD pipeline come to a halt."
"We have faced challenges with the availability of mobile devices. There was once or twice where there were no mobile devices available."
"The 7-days scheme should be removed."
"The connectivity needs improvement."
"Another aspect that could be improved is having the virtual devices boot up a little quicker. Sometimes we wait up to a minute before a device is available. It would be nice if that was 30 seconds or so."
 

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 pricing is definitely on the higher end, and there are other options that are more cost-effective."
"They could improve on the pricing because it seems pretty expensive. I'm sure it's justified, but it's expensive."
"Cost-wise, it's decent. If you have to get the base version out of it, it's the best solution to go with. As compared to other cloud service providers, the pricing of Sauce Labs is decent."
"Their pricing is incredibly competitive."
"It is an expensive tool."
"We have an enterprise account; it has worked great for our needs."
"With respect to pricing, they did a bundled discount because we went with Sauce Labs for both mobile and browser. They were very competitive on pricing and provided a bundle discount for us as a larger customer."
"Go ahead please. Try it at a smaller scale."
