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

"The most valuable aspect of the solution is that it covers all types of devices on the market allowing you to test different versions of an operating system."
"Performance-wise, Perfecto has been awesome."
"It has saved hours of manual testing time, costs and efforts."
"When the scripts are stable, Perfecto is awesome."
"Perfecto is a game-changer for us, we save at least $10,000 monthly."
"We are able to offer a quality product that has been tested fully, which improves our customer satisfaction. That is a good thing. It has also reduced our IT infrastructure cost. We don't have to spend a lot on setting up infrastructure, which becomes redundant or obsolete very soon. It helps in offsetting that cost."
"Being able to run automated tests and see the success and failure rate of those runs every day has saved us a lot of time and helped us identify issues much sooner, which has improved the quality of our software."
"Their team is really great to work with. They're very flexible, and they always show care. They prioritize our work, our company, and our working relationship. I appreciate the ad hoc sessions that they schedule to provide help with troubleshooting, provide the information that we're looking for, or do a demo of a new feature that they have. They're always willing and very quick to get that scheduled for us. I appreciate that a lot."
"In case something goes wrong at LambdaTest end, the Support team is extremely responsive to analyze any platform-related issues."
"LambdaTest is easy to use, and the documentation provides all the needed information."
"LambdaTest is brilliant."
"Without a doubt, LambdaTest is one of the big reasons behind our faster deployment and better team collaboration."
"The slow nature of a cloud platform was compensated with parallel testing, and now we are able to finish our testing job faster than it was before COVID."
"LambdaTest supports multiple platforms like iOS across different devices and enables real-time testing."
"Using LambdaTest, we could run all our functionality tests across various browsers, OS, and resolutions."
"Geolocation testing is as straightforward as ticking checkboxes of browsers, operating systems, and countries."
 

Cons

"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."
"There was a discussion about having the capability to export the test results to a certain tool that we use in our project. If that were added it would be great not having to manually take screenshots, put them in a document, and share them on the different test management tools."
"There could be some improvements done on the interface. At times, there has been a bit of a struggle when finding things on the interface. A UI revamp would be a better option in future. That UI hasn't changed much in a long time, so I think they could just make it a bit better so that people could find stuff easily and intuitively."
"When using devices on the cloud, it lags quite a bit at times. I know that these are real devices that are being projected on our laptop screens and monitors, but if the speed could be improved, that would be good."
"I'm hoping they can support on-premises instances."
"In iOS, it needs improvements with some limitations."
"We feel that Perfecto is a little slow. If they could improve on that slowness in accessing the app, when we want to click a button, that would be great because we feel the difference. An improvement in the connectivity speed is required."
"I would like to see the inclusion of machine learning features. If we can have that, it will be a better tool."
"Responsive testing UI is a bit cluttered, whereas the LT browser is much better to use."
"Sometimes, when multiple users use the tool simultaneously, it can slow down, affecting efficiency."
"You cannot perform native-app testing, as they offer simulation for web testing only."
"Improvements on a platform need to happen on a timely basis...There should be some new features coming up or some performance improvisation over a period of time."
"Mobile application testing will be an added benefit for us if LambdaTest implements this really soon."
"For us, Cypress! It looks like the support for Cypress is not there."
"The scalability is good with Amazon, but IBM had some issues."
"Analytics could be better because as of now, it gives basic information on test status and build status."
 

Pricing and Cost Advice

"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 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."
"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."
"This is an expensive solution compared to others, by 30% to 40%."
"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."
"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."
"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."
"It is 60% cheaper and there is no fuss in maintaining the lab, so we have more time to do the testing."
"The product can be described as an averagely-priced solution."
"LambdaTest's pricing is cheaper than that of other similar platforms."
"I used the product for free."
"It is affordable as compared to similar SaaS solutions."
"LambdaTest is paid per execution."
