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."
"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."
"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."
"Sauce Labs is optimized for automation and integration with the major CI/CD platforms and developer tools. We have an integration with App Center that we're working on. They have a storage API that lets us retrieve APK and IPA, iOS and Android builds off the phone, so that we can continue testing with CI/CD. They integrate with Jenkins, and Jenkins is the main CI/CD."
"The configuration and options within Sauce Labs are endless, which makes it an excellent product."
"Sauce Lab analytics helped us to get detailed knowledge on test cases execution and logs."
"Sauce Labs tool has improved my testing efficiency to allow me to include devices I may not have had time to test out before."
"It helped to integrate our performance testing and UAT, which helped to deliver a bug free software for our customers."
"All features are excellent, especially the parallel runs."
"With only a few clicks, it gives us the availability to use any browser and OS combination whenever we want."
"My general overall impression of Sauce Labs is very positive."
 

Cons

"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."
"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."
"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."
"With the desktop browser, we can inspect any screen with the web developer option, but they should provide something for mobiles so that we can quickly inspect elements on the device. To write the Selenium scripts, we require web locators. We have to capture them from the local and execute the script on Sauce Labs. If Sauce Labs can provide a solution where we can inspect any of the mobile devices online, it will be very helpful for us."
"Start execution time as each time a set of tests start, it will launch a new VM so it takes a bit of time."
"Sometimes the tests can pass or fail inconsistently. The tunnels and jobs timeout before the app loads, or it has to try 3 or 4 times to get a good connection."
"The way the owner/user/sub-user hierarchy is set up can be confusing."
"Rarely, some tests fail, seemingly without cause, and will succeed again the next time we run the tests."
"Documentation and speed."
"I only tried the free trial so far, so not a lot to say about the cons."
"It would be very good to see a short example of the code that needs to pass into Driver capabilities, something like auto-generation of this block."
 

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."
"Try the free trial and work with a Sauce Labs representative to see what package works best for your application(s)."
"Trial the product and see if it suits your needs."
"The pricing is reasonable due to the amount of diversity that they provide. However, I feel they might be more flexible to bargain based on their relationship with our organization."
"They could improve on the pricing because it seems pretty expensive. I'm sure it's justified, but it's expensive."
"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."
"​Now that we have an enterprise license, we no longer have to worry about minutes each month!​"
"It could be less like pay-per-use with a lower rate."
"The number of concurrent VMs that Sauce Labs provides depends on your purchase license level."
