Manager of Central Excellence at Alpura
Easy to set up with good documentation and easy management of testing cycles
The solution allows for a complete test cycle. The management of testing cycles are easy. We have good control over test cases. We can capture functional testing very easily. We're actually able to accelerate testing now and have end-to-end cycles for testing. We didn't used to have these capabilities. It's easy to automate and accelerate testing. The product offers very good cross-browser testing capabilities. We can do continuous testing and regression testing.

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

"A good automation tool that supports SAP functional testing."
"The major thing it has helped with is to reduce the workload on testing activities."
"The statistics that are available are very good."
"It's easy to automate and accelerate testing."
"The ability to develop scripts in Visual Studio, Visual Studio integration, is the most valuable feature."
"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."
"The scalability of the solution is quite good. You can easily expand the product if you need to."
"The feature I like most is the ease of reporting."
"Without a doubt, LambdaTest is one of the big reasons behind our faster deployment and better team collaboration."
"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."
"It is a scalable solution."
"LambdaTest is easy to use, and the documentation provides all the needed information."
"The support docs are precise and you can get started with them easily."
"LambdaTest offers geolocation testing in automation, which is amazing!"
"I was really surprised by LambdaTest; it was a very good service and for the price, I think it is a very good solution."
 

Cons

"The support for automation with iOS applications can be better."
"Could be more user-friendly on the installation and configuration side."
"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."
"They should extend some of the functions that are a bit clunky and improve the integration."
"The pricing is an issue, the program is very expensive. That is something that can improve."
"The pricing could be improved."
"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."
"I think Lambdatest is a valuable tool for our team and things that have room for improvement would be mobile app testing, as it can be an important addition to the tool."
"I would like to see all of the features available in the freemium plan so that I can test them."
"Sometimes, when multiple users use the tool simultaneously, it can slow down, affecting efficiency."
"LambdaTest needs to have native application testing, which would be a great help to my team."
"There is scope for improvement in service account usage, LDAP integration, and adapting new devices and features."
"Their smart testing module needs improvement."
"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."
"Responsive testing UI is a bit cluttered, whereas the LT browser is much better to use."
 

Pricing and Cost Advice

"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."
"It is 60% cheaper and there is no fuss in maintaining the lab, so we have more time to do the testing."
"I used the product for free."
"LambdaTest is on the cloud, offers both free and paid plans which start at $19 USD per month."
"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."
"The product can be described as an averagely-priced solution."
"It is affordable as compared to similar SaaS solutions."
"The pricing for LambdaTest is affordable, and one of the reasons we implemented it."
