QA Lead at BMO Financial
Its reporting allows us to have a clear view regarding what tests have been executed
The most valuable would be their Live Stream analysis, where I can see the live analysis of all the executions on a single device or multiple devices as well as track them. The live analysis and reporting would be the single most valuable feature. We leverage Perfecto’s reporting and analytics a lot. From the CI Dashboard, it is mainly the status, which is the past, failure count, and time consumption, e.g., how much time did an average test or script take? Along with that, it provides the historical view compared to the previous result, e.g., am I a pass or fail? Also, the stack trace is very important. Whenever a pass occurs, we don't look beyond that. However, whenever a failure occurs, the stack trace information that it gives us is pretty critical for us when figuring out where failures lie. It gives a summary for the pass/fail count, total test count, the historical view, time consumption for each test as well as the total tests, and the stack rate of the failure. Perfecto's analytics are very important since we use them on a daily basis. We run our executions daily. After every execution, we pull information from the Perfecto reporting system and share that with our stakeholders. Having this information accurately reported is pretty important for us, so everybody is aware of the current status of the product. That way, we can evaluate the health of the product or environment against that which has been executed. Therefore, it helps make those real-time decisions and highlights the impact to the business. I found Perfecto to be pretty easy to use while executing against cross-platforms. The main reason is because the same script or test automation where we execute on multiple platforms has minimal changes that I need to do. Also, it is easy for me to set up an execution on one platform, then on another platform, either in parallel or one after the other. Parallel opportunities save me time. Once the execution has been completed across these different configurations, I can always check and compare, e.g., what are the differences and consistencies? We utilize Perfecto’s cloud-based lab to test across devices, browsers, and OSs. I use it occasionally for manual testing. Though, there are other team members who use it more frequently than I do. I use it mainly for executing my automated tests. We have the Perfecto lab, cloud devices, and machines. I can program my test to execute against any of those devices, which gives me more confidence in my product. I can compare and see how my product or application functionally behaves across these different devices and from a UI point of view, which helps me a lot. The device lab is extremely important to our testing operations. We rely on having multiple devices up and running all the time. Whenever we kick off an execution, there are multiple reasons why executions may get triggered: * CodeCommit * A scheduled job. * Might be on-demand by any stakeholder. We need the lab to be available, as we need devices up and running for executions to take place. Also, the devices help since they allow us to have parallel execution, and not just wait for a sequential device to become free and available. Therefore, volume is definitely key. It also gives us an opportunity to compare execution across platforms in that space. It is extremely important to you that the lab provides same-day access to new devices since we analyze that data every single day after execution. Perfecto provides their own framework called Quantum Framework. That is one option. The other option is, if I want to have my own framework, I can have a Java-based Maven project, take a Selenium library, AppiumLibrary, and REST Assured library, and utilize the open-source framework. It is easy for us to connect to Perfecto, no matter what framework we use, as long as it has these core libraries in it. I can design and structure it any way that I want. The execution will happen in Perfecto no matter what since they have support for these tools or libraries. It is pretty neat that way. We are not dependent on using just one particular framework to use Perfecto. While there are still some framework limitations, there is the opportunity to use multiple, different open-source frameworks, then pass the execution to Perfecto. We can use most frameworks, then design and craft it any way that we want, then just pass the execution to Perfecto.

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 Perfecto's ability to perform cross-platform testing, I would rate it a ten out of ten."
"Performance-wise, Perfecto has been awesome."
"Overall, it results in huge cost savings for our company."
"Perfecto's device lab has helped us to scale our testing and it has made testing easier for us."
"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."
"Mobile testing is the most valuable feature as it has reduced dependency on physical devices. We are located offshore and we don't have the physical devices, and shipping physical devices after every new release would be a difficult task. But with Perfecto, it is easy."
"There are a whole bunch of things that I like about the solution, but I really love the interaction it has with mobile devices, the testing capabilities, as well as reporting capabilities that we get from the application. The reports are very detailed."
"When the scripts are stable, Perfecto is awesome."
"It’s good to see, now that we are using LambdaTest, we can run multiple tests on multiple VMs, saving us hours of testing time and the maintenance cost of local infrastructure."
"The solution is very easy to understand and has a user-friendly UI."
"The support docs are precise and you can get started with them easily."
"Geolocation testing is as straightforward as ticking checkboxes of browsers, operating systems, and countries."
"It provides 2000+ browser-OS-resolution combinations to work with, which is perfect for our consulting firm, as we don't know what our clients may need."
"The most valuable feature is the real-time testing, which helps you to test your website on more than two thousand combinations of browsers and operating systems."
"LambdaTest Selenium Grid has helped us radically reduce the manual testing effort and ensure browser compatibility."
"HyperExecute adds significant speed to execution, enhancing the overall testing process."
 

Cons

"We don't use Perforce's BlazeMeter with Perfecto. From my perspective, it's not really relevant."
"I'm hoping they can support on-premises instances."
"It does well for mobile testing, but when it comes to the web aspect, it is lagging a little bit in terms of execution."
"The flakiness, or the accuracy, of the test execution can be improved. Also, the responsiveness of their cloud lab could be improved as well."
"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."
"I would like to see the inclusion of machine learning features. If we can have that, it will be a better tool."
"Sometimes, when the automated tests sync up or we have to debug remotely, we cannot interact directly with the device."
"I feel that the automated screenshot testing takes a little longer on MacOS sometimes."
"Performing automation testing from UI is a little slow and could be improved."
"If possible to simulate the finger pinch, it would make it more realistic."
"Their smart testing module needs improvement."
"The analytics over the automation dashboard can be more intuitive."
"Load flow compared to other stacks needs improvement."
"Mobile application testing will be an added benefit for us if LambdaTest implements this really soon."
"I've also had some issues with the speed of certain API calls and the rendering of data. For example, when I'm onboarding data, the process can be slow."
 

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."
"It's definitely on the higher end of prices for this type of service."
"Pricing-wise, it is fine. It is not as expensive as what we used to have in the past from HP, IBM, and others. It is decently priced."
"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."
"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."
"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."
"This is an expensive solution compared to others, by 30% to 40%."
"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."
"It is free to start, which means you can actually see how it works and then take the decision to buy."
"LambdaTest's pricing is cheaper than that of other similar platforms."
"LambdaTest is on the cloud, offers both free and paid plans which start at $19 USD per month."
"The pricing for LambdaTest is affordable, and one of the reasons we implemented it."
"From the customer side, LambdaTest is cheaper for big company usage and works fine as other similar applications."
"LambdaTest is paid per execution."
"The tool is not cheap, but it is not expensive."
"This is an affordable product."
