Reliable test automation, and test data creation with efficient support

The solution can be improved by removing the need for object matching in the framework. The latest version has increased load time before testing can be run. The reason is that changes were made to how it works with the browser and the startup takes some time. Adjusting those changes to speed up the load time will improve the solution.

Stable, with good statistics and detailed reporting available

While we are performance testing the engineering key, we need to come up with load strategies to commence the test. We'll help to monitor the test, and afterward, we'll help to make all the outcomes, and if they are new, we'll do lots and lots of interpretation and analysis across various servers, to look at response times, and impact. For example, whatever the observations we had during the test, we need to implement it. We'll have to help to catch what exactly is the issues were, and we'll help to see how they can be reduced. Everything is very manual. It's up to us to find out exactly what the issues are. The solution needs better monitoring, especially of CPU.

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

"Test automation is most valuable because it saves a lot of time."

"IBM Rational Functional Tester is very contextual."

"It is compatible with all sorts of Dark Net applications. Its coverage is very good."

"The most valuable feature is the UI component tester."

"The statistics that are available are very good."

"A good automation tool that supports SAP functional testing."

"It's easy to automate and accelerate testing."

"The feature I like most is the ease of reporting."

"The ability to develop scripts in Visual Studio, Visual Studio integration, is the most valuable feature."

"The major thing it has helped with is to reduce the workload on testing activities."

"The scalability of the solution is quite good. You can easily expand the product if you need to."

"Scripting is the most valuable. We are able to record and then go in and modify the script that it creates. It has a lot of generative scripts."

"It has a wide assortment of platforms."

"Testing my app on cloud has really helped us with save time and resources to procure various hardware and software, and set those up."

"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."

"I never faced any issues with the stability."

"The solution they provide is very robust. We can quickly connect to their environment with the hub URL. They have a URL that has the entire grid of desktops, web browsers, and mobile devices. They also provide real devices, so you just provide the URL and test your application."

"Live device testing. As we all know, It's really hard and challenging to find/purchase many real devices to test because it will be costly and not all the team can be able to purchase all of the devices out there. We used to have a lot of real devices under our labs. However, it is really time-consuming to maintain those devices and make sure they are up to date with the testing requirements."

"With Sauce Labs, we have a whole universe of devices: Galaxy, all the iPhones, and all the operating system versions. All our software developers are able to test on a multitude of different devices."

"The abundance of device, platform, and browser combinations/versions that can be used in parallel."

More Sauce Labs pros

Cons

"If the solution is running on Linux, there are some issues around application compatibility."

"As many of our products are moving from PC to mobile, the most important thing that this solution needs is mobile app support."

"They need to do a complete revamp so that even a non-technical person can manage the tool."

"The latest version has increased load time before testing can be run."

"The solution has a lack of compatibility with newer technologies."

"Everything is very manual. It's up to us to find out exactly what the issues are."

"Could be more user-friendly on the installation and configuration side."

"The support for automation with iOS applications can be better."

"The pricing is an issue, the program is very expensive. That is something that can improve."

"We moved to Ranorex because the solution did not easily scale, and we could not find good and short term third-party help. We needed to have a bigger pool of third-party contractors that we could draw on for specific implementations. Silk didn't have that, and we found what we needed for Ranorex here in the Houston area. It would be good if there is more community support. I don't know if Silk runs a user conference once a year and how they set up partners. We need to be able to talk to somebody more than just on the phone. It really comes right down to that. The generated automated script was highly dependent upon screen position and other keys that were not as robust as we wanted. We found the automated script generated by Ranorex and the other key information about a specific data point to be more robust. It handled the transition better when we moved from computer to computer and from one size of the application to the other size. When we restarted Silk, we typically had to recalibrate screen elements within the script. Ranorex also has some of these same issues, but when we restart, it typically is faster, which is important."

"They should extend some of the functions that are a bit clunky and improve the integration."

"The pricing could be improved."

"Every time that we run scenarios where we need to discover the geolocation of our customers, by default it shows as Palo Alto, California. That's a problem for us and we need a workaround for those cases... It would be helpful if we could enter a latitude and longitude into Sauce Labs configuration and say, "When you run a virtual Chrome device or an iPhone, make this your default location. Then, provide me that device so I can run my scenarios," because we have stores in different regions across the United States."

"The testing process is difficult. I need to prove the complete competency of the tool, and I am finding that challenging."

"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."

"Integration with Github, as well as several other similar tools, could be improved."

"Sauce Labs can include new technologies like generative AI capabilities."

"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."

"I would like to see improved network connectivity and it should allow playback for native apps."

"Sauce Labs' dashboard could be improved by adding more filters and allowing more customization options. There was one instance where the dashboard on the Sauce Labs UI didn't meet our requirements, so we had to use the Sauce Labs API to create some apps and dashboards on our own. The API endpoints could be a little more robust and customizable."

Pricing and Cost Advice

"Licensing is good but the prices for the products are expensive. A single-user license may go for something like $10,000 to $30,000. There are no additional costs, and support is included within that price."

"We paid annually. There is a purchase cost, and then there is an ongoing maintenance fee."

"Our licensing fees are on a yearly basis, and while I think that the price is quite reasonable I am not allowed to share those details."

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

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

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

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

"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."

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

"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."

Reviews from Real Users

Sauce Labs is a solution that stands out when compared to many of its competitors. It has valuable features that include error logging, helpful dashboards, and its browser.

Joel A., Product Manager - Data & APIs at a marketing services firm, says, "The error logging is very robust. If we run a test through Sauce Labs and there's some sort of issue, a log will appear on the screen. Log messages are usually heinous and horrible... Sauce Labs is incredibly good at saying things like, 'Hey, here is the exact issue. Fix this and you can run the test.' That helps in getting things up and running and executing the way they should."

Savio D., Sr. IT Architect at a healthcare company, mentions, "Sauce Labs' dashboards contain multiple useful metrics in one place. Everything is represented to us visually on the dashboard, which helps us understand where to focus our attention, what the issues are, and what we need to resolve."

PeerSpot reviewer, Rob L., Director of Quality Assurance - Shared Service at a financial services firm, writes, “The most valuable feature for us is the browser. The most critical thing is that this software aligns with our Agile and DevOps way of doing things. It integrates with kickoff scripts through DevOps.”
