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 multiple test environments and saves time, but should have something for inspecting mobile apps screens
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. I also faced an issue where during the execution time, the iCloud password used to expire within a certain period, which used to create pop-ups on the screen making our tests fail. That was one thing that we faced many times. If that can be improved, it will be very helpful.

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."
"APPIUM for mobile testing has improved our organization by allowing us to test our website on more devices and browsers than we currently possess."
"It provides a comprehensive selection of browsers and platform versions for our test automations and CI/CD pipeline process. It also provides a comprehensive set of virtual mobile devices, which we can configure for our automation and availability. These features are valuable for us when it comes to testing our applications. We have a website and mobile applications that we want to test and diversify to various browsers and mobile devices as well as restore various versions. This helps us to find bugs that users might be facing and correct them."
"The abundance of device, platform, and browser combinations/versions that can be used in parallel."
"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 Failure Analysis feature is really important for us, one of the most important aspects. What is the root cause? Is it because we have a defect or is it that we have a test case that we need to fix or modify? The Failure Analysis is one of the main functionalities that I am exploring all the time in Sauce Labs... The Failure Analysis helps us to discover which test cases we need to work on."
"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."
"They offer a large number of devices and browser/operating system combinations for real device tests"
"Testing subscription videos for on-demand software, making them better quality and bug free for our customers."
 

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."
"They should provide a JIRA integration plugin so that we can easily log issues."
"One of the challenging areas for us is the reporting and the matrix. It should be based on roles, but right now it is only available for the admin role. The admin role can really do a lot of stuff, but our infrastructure team, which holds the admin role, is not ready to hand it over to us on the testing team. If Sauce Labs had permissions associated with roles, where this role could do this activity and that role could do that activity, it would be easier for us."
"Latency, due to Sauce Labs being a cloud-based solution, has been a concern. We work in different continents and countries, but last time I checked, Sauce Labs was only offering two data centers, one in the EU and another in the US. If you're not in either of those two places, you would have latency and issues running your test cases."
"An image comparison would be a nice feature to include in the Sauce Labs product."
"I would like to see improved network connectivity and it should allow playback for native apps."
"Unable to segregate reports for tests that are currently being developed, and might not be returning useful results."
"The real concern is the load time of applications or real devices when we start our tests. It takes some time to load the application or web browser. Sometimes, it is frustrating too. Since they are real devices, we understand it takes some time to load. However, if it were to improve, then that would be a great asset to the solution. So, we would like better responsive times when opening applications and running tests."
"The Jenkins Sauce OnDemand plugin could have more options available to tap into more of the custom capabilities Sauce Labs actually supports."
 

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."
"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."
"When you reach the Enterprise licensing tier, base level being with 10 concurrent test sessions, pricing is essentially per-unit-of-concurrency thereafter with a relatively linear increase and not much benefit for "bulk"."
"Go ahead please. Try it at a smaller scale."
"Trial the product and see if it suits your needs."
"We have an enterprise account; it has worked great for our needs."
"It could be less like pay-per-use with a lower rate."
"Compared with other services, Sauce Labs is a bit expensive."
"The pricing is definitely on the higher end, and there are other options that are more cost-effective."
