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.

Offers good stability and robust but lacks generative AI capabilities

Technical support is equally very important. If you talk about anything deployed to production, and the project is live, customers are using that, and they might face some issues, some functional issues. That's when support people play a role in identifying the fix or the incident. Based on that, we create an incident based on the customer defect or whatever. Once the incident gets raised, the support will play a role in working on that particular incident. If it's a code-based incident, administration, or integration issue, support people play a big role in resolving those issues before reaching the exact developers.

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."

"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."

"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."

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

"I have found the live test section with Sauce Labs to be extremely valuable. When you can't quite figure out why a test is failing, you can go to the live test results section within their tool and launch your test (specifying a given OS/browser, or device) manually and step through the test to see the issue more clearly, usually opening up the developer's tool console and watching the network calls and console (within Chrome) to usually find the underlying issue."

"However, Sauce Labs is incredibly easy to use and has enabled me to make some changes so that the sites are (almost) universal across the range of devices and versions."

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

"A cross browser test platform is really important for a web designer, Sauce Lab providing a really fast, functional and with good quality service."

"With Sauce Labs, we are able to cover multiple Chrome, Firefox, and Safari variations to support and test for all users."

"Customer service is 10/10; Sauce Labs is quick to help and easy to reach out to for information or troubleshooting."

"From an infrastructure support perspective, the number of VMs, browsers installations and versions that we would be maintaining without Sauce Labs would be a lot. This includes not only the infrastructure costs, but also the maintenance costs and people's time. The labor cost associated with maintaining all of that would be considerably high. In terms of efficiency, having concurrent VMs with various browser combinations available has allowed us to run multiple executions by all our teams."

"Cross-platform mobile testing. Before using Sauce Labs, I would have to setup a Selenium Grid cluster and install all versions of mobile simulators/emulators in order to test apps on different platforms."

More Sauce Labs pros

Cons

"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."

"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."

"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."

"An image comparison would be a nice feature to include in the Sauce Labs product."

"The pricing model of Sauce Labs could be more flexible. Sauce Labs has just one price for the type of solution and a set number of devices. Other solutions have a fee for the base solution and an additional cost per device. If you're a smaller organization, you have to consider your needs. Some smaller companies still need to test various devices, so my advice is to start small and scale up as needed. We had initially planned to start big, but that would have been a big waste."

"Sauce Labs' dashboard could be improved by adding more filters and allowing more customization options."

"Start execution time as each time a set of tests start, it will launch a new VM so it takes a bit of time."

"Sauce Labs needs to be improved in the different platforms for farm testing, like iOS and Android farm testing and farm testing web browsers."

"They could improve on the pricing because it seems pretty expensive."

"Speeds up the time it takes to run end-to-end user interface (UI) tests inside their virtual machines (VMs)."

"On a rare occasion, I will come into a ticket where a customer will have reached out to me after reaching out to Sauce Labs, saying, "Sauce Labs doesn't understand what I am going through. They are not being very helpful." So, I try to do clean up there. Outside of those extremely rare occasions, I have only had one or two of those support issues."

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."

"Compared with other services, Sauce Labs is a bit expensive."

"It is an expensive tool."

"Trial the product and see if it suits your needs."

"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."

"The number of concurrent VMs that Sauce Labs provides depends on your purchase license level."

"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."
