Executive SummaryUpdated on Dec 15, 2024

IBM Rational Test Workbench and Sauce Labs are both products in the testing automation solutions category. Sauce Labs is more advantageous for its cloud-based testing capabilities which are essential for mobile and web app developers.

Features: IBM Rational Test Workbench offers robust test management, advanced automation capabilities, support for various test automation types, and extensive reporting, making it suitable for complex integration scenarios. On the other hand, Sauce Labs provides a cloud infrastructure with access to thousands of browser and OS combinations, continuous testing, integration support, and scalability, making it ideal for agile teams focusing on quick releases.

Room for Improvement: IBM Rational Test Workbench can enhance its ease of use and simplify initial setup processes. It could also improve cloud-based capabilities and integrate better with non-IBM tools. Sauce Labs could enhance its debugging features further, improve offline support, and offer more in-depth training resources for users new to cloud testing environments.

Ease of Deployment and Customer Service: Sauce Labs features an accessible cloud-based deployment model that reduces infrastructure needs and shortens setup times, alongside responsive customer service. In contrast, IBM Rational Test Workbench involves complex on-premises deployment with longer implementation times, although it provides reliable support.

Pricing and ROI: IBM Rational Test Workbench involves higher initial setup costs because of its licensing and deployment requirements but can deliver substantial ROI for enterprises needing robust testing in an IBM environment. Sauce Labs benefits from a SaaS pricing structure, offering flexibility, scalability, and a lower initial investment, potentially delivering a faster ROI for organizations with significant testing demands.

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

"Using service virtualization, we are able to accelerate the testing and development activity."

"Reporting is pretty good. Its interface is also good. I'm overall pretty happy with the functionality and use of IBM Rational Test Workbench."

"All IBM testing tools are really well integrated."

"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."

"This solution provides for API testing, functional UI testing, performance testing, and service virtualization."

"It improved our organisation by reducing escaped bugs."

"Has freed up huge amounts of time managing integrations."

"No need to purchase more real devices."

"Yes, it allowed us to scale mobile testing across the globe."

"I cannot imagine our company without Sauce Labs."

"Prior to implementation we had a three month release cycle; using Sauce Labs we were able to move to daily releases."

"What I like most is the parallel run for multiple tests on multiple browsers simultaneously."

"Parallel test execution helped us a lot to reduce test time."

"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.

"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."

"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."

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

"Another feature that could still be improved on is more error clarity. Sometimes when running automated scripts the test will fail on the device side instead of the script and errors only show a 500 try again message instead of a detailed script that could of a been a timeout error from the code."

"The complexity of setting up the tunnel comes mainly from the protocols our organization has for getting the approval to implement Sauce Labs behind our firewall."

"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."

"Multi-domain SSO is a big concern for us right now, especially as we've been merged into a larger company. I suddenly have teams coming from 20 different domains, and because the main master Sauce Labs account is locked down to one SSO domain, there are teams that can't run a test right now. I've heard they're working on a solution and they've been very communicative with us about it. A solution to that would help us a lot."

"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."

"There have been various times throughout the last month or so where the service has gone down during business hours."

"Rarely, some tests fail, seemingly without cause, and will succeed again the next time we run the tests."

"I think it should be a longer trial period with more parallel tests available."

More Sauce Labs cons

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)."

"We have an enterprise account; it has worked great for our needs."

"Go ahead please. Try it at a smaller scale."

"They could improve on the pricing because it seems pretty expensive. I'm sure it's justified, but it's expensive."

"We did initially go with Sauce Labs because of the pricing and integration."

"It could be less like pay-per-use with a lower rate."

"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"."

"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."
