Software Quality and Automation Specialist at PRIME CONTROL

The solution saves us money because the cost of each license is 10 times lower than what we would spend to maintain infrastructure here

Sometimes, when the automated tests sync up or we have to debug remotely, we cannot interact directly with the device. We can interact with the code in the debugging tool, but we cannot directly click on the element on the screen or send other kinds of inputs to the device. This is possible with other tools. Also, it would be nice if there were some kind of API to get a list of available devices. Currently, we have to look at the web interface to see the available devices, but the pipelines can't do it on their own there. We always need to do this manually, so it would be better if this feature was automated.

Cloud-based testing has simplified remote mobile validation and provides flexible device coverage

I was not impressed with how detailed their analytics and logs are from LambdaTest. The solution we were testing is being used because many of us are working from home. It was easy to implement because with a real phone, we have to bring a real phone to each person. Since three years ago, many employees have been working from home, so we were trying to find a solution for this challenge. We had no need to exploit the information for the analytics generated in the background. The purpose was simply to make it easy for our employees to access a phone. The downsides I noticed include that the pricing was very good, but the visual quality of the image sometimes suffers. The contrast on a real iPhone provides better contrast than with the cloud solution. The only aspect that was less favorable than on a real phone was the contrast of the color.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:

Pros

"In terms of cross-platform testing, they offer all of it, every device available in the market. It covers real scenarios that mimic production so that we don't miss out on any devices that our clients might be using to run the applications we develop. It's been great and very helpful."

"When the scripts are stable, Perfecto is awesome."

"Perfecto has affected our software quality in a good way; it has allowed us to catch our defects earlier, thus improving the quality of our applications."

"I also like the reporting functions. We are constantly downloading these reports and sharing them with our final customers. They help us understand what kind of bugs are happening through the applications. The recording feature is handy because it lets us see a video of the process we run through the pipeline and discover the point at which the automation is breaking."

"One of the good things about Perfecto is the scalability that it provides."

"Overall, it results in huge cost savings for our company."

"It creates a faster production cycle and is quick to market. Things get deployed earlier because the testing happens on time. We can do a lot of panelization, so a lot of test phases can happen in a panel. People don't have to wait for a device to come to them. They can access multiple devices at the same time and do testing at the same time."

"Overall, it's a great solution."

More Perfecto pros

"Stability-wise, I have not experienced any downtime or other performance issues."

"Builds that took days to complete with in-house infrastructure were executed in a couple of hours."

"HyperExecute adds significant speed to execution, enhancing the overall testing process."

"LambdaTest supports multiple platforms like iOS across different devices and enables real-time testing."

"With LambdaTest, we could see improvements in identifying errors before our customer does."

"Automation and mobile testing have improved our efficiency."

"LambdaTest easily integrates with leading project management, bug tracking, and CI-CD tools like Jira, Asana, Jenkins, Circle CI, and more."

"The UI is pretty clean and easy to navigate, and we were able to figure it out very quickly."

More TestMu AI (Formerly LambdaTest) pros

Cons

"It is slow compared to physical device testing. The interactive speed could be improved."

"I'm hoping they can support on-premises instances. We have been working on a JIRA integration with Perfecto—and I'm extremely impressed that they have that—but at this time they're not supporting onsite JIRA instances, which is what we have."

"We have had some issues with performance, which is something that should be improved."

"In iOS, it needs improvements with some limitations."

"Sometimes, when the automated tests sync up or we have to debug remotely, we cannot interact directly with the device."

"So, overall, I would rate Perfecto a seven out of ten because sometimes, we also have lagging with some of the devices. We get error messages, but we're not quite sure what's causing them."

"It would be nice if there were some kind of AI to compile a list of available devices. Currently, we have to look at the web interface to see the available devices, but the pipelines can't do it on their own there. We always need to do this manually, so it would be better if this feature were automated."

"Its performance should be improved. Anything to speed up the user interface would be a great help. We've had a lot of pain with their migration from a product UI that was based on Adobe Flash to the new product that is based on HTML5. Migrations like that seemed to be very painful and not a real smooth process. We're still sort of recovering from that migration from old technology to new, and we haven't got all the functionality ported over that we used to have on the old UI."

More Perfecto cons

"Mobile application testing would be helpful for us."

"Responsive testing UI is a bit cluttered, whereas the LT browser is much better to use."

"You cannot perform native-app testing, as they offer simulation for web testing only."

"It would be much easier for us to read the test if they provided dashboard analytics."

"LambdaTest needs to have native application testing, which would be a great help to my team."

"Their smart testing module needs improvement."

"Performing automation testing from UI is a little slow and could be improved."

"The scalability is good with Amazon, but IBM had some issues."

Pricing and Cost Advice

"Pricing is an area where Perfecto can do a little better. When we obtain additional licenses, we enter into negotiations with them."

"Perfecto has definitely saved us on the costs and efforts of having to maintain our own virtual test environment. We lost about 20 devices in the past to maintenance and audit. That was a massive loss for us, as a company, because we were giving devices to someone, but don't know whether we would get it back or not. Having those virtual labs, we don't need to worry about these kinds of things. We are easily saving $5,000 to $10,000 a month on device costing."

"It's definitely on the higher end of prices for this type of service."

"I am not sure about its pricing, but from our perspective, licensing has been easy. Anytime I have new users or requests for users that want to get added, it's a very simple process. I just give the architectural owner of the product the name and email address, and they're able to easily add a new user. We don't have any issues in regards to getting licenses, but I don't have any insights into pricing."

"Perfecto's price is excellent compared to other products with similar features. It was the lowest of the three we evaluated. We also established a partnership with Perfecto, so they provide discounts when we sell Perfecto projects and licenses to our customers."

"Perfecto is about 30-40% cheaper than Device Anywhere. That was a big reason why we switched. Perfecto also solves some of the issues that we had with Device Anywhere. We have grown by 100% since we started to use Perfecto, and now we have devices roaming. When we look at the competition, we would still stick with Perfecto."

"Although Perfecto is a good product for us to use, it is a bit expensive. It takes management a bit of work to find the appropriate funding for us to keep Perfecto. I imagine there could be some way to make it more accessible."

"This is an expensive solution compared to others, by 30% to 40%."

More Perfecto pricing and cost advice

"LambdaTest is on the cloud, offers both free and paid plans which start at $19 USD per month."

"I used the product for free."

"It is free to start, which means you can actually see how it works and then take the decision to buy."

"This is an affordable product."

"LambdaTest is priced well, which is why we migrated to it."

"It is 60% cheaper and there is no fuss in maintaining the lab, so we have more time to do the testing."

"The tool is not cheap, but it is not expensive."

"From the customer side, LambdaTest is cheaper for big company usage and works fine as other similar applications."
