ReadyAPI Test needs to improve its reporting. While reports provide essential information when issues arise, or tests fail, having more graphical representations directly within the reports would be beneficial. It needs to improve stability and scalability as well. The tool's support is slow, and takes months to reach a solution.

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

"It clearly makes it easy to test APIs based on the SOAP protocol. We are a logistics company, and we have lots of tracking calls coming in. We provide APIs for tracking services, and it makes sense for us to use SoapUI to test them thoroughly."
"SoapUI is very useful; before we started using SoapUI, we had to do everything manually, which is very time-consuming, and there were a few things we couldn't validate, but using SoapUI made everything easier, you can do six to seven hours of work efficiently, and it's more flexible to use."
"The most valuable features are that it is user-friendly, it's easy to use and easy to teach to others."
"For the money this is a great tool."
"Great tool. Makes API testing super easy to set up and use."
"The utmost importance lies in the performance of the application."
"The Pro and free version of SoapUI Pro has good technical support."
"We are using SoapUI Pro as an API testing tool, and we do API building, testing, and tracking."
"With LambdaTest, we could see improvements in identifying errors before our customer does."
"In case something goes wrong at LambdaTest end, the Support team is extremely responsive to analyze any platform-related issues."
"It's user-friendly and offers valuable features for testing, making it a reliable tool."
"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."
"It is a scalable solution."
"Automation and mobile testing have improved our efficiency."
"Our test execution time was reduced to 16 mins from five hours when executed in parallel on multiple VMs. This has been extremely helpful!"
"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

"SoapUI Pro could improve by having dashboards."
"Grouping of the cases is not possible in SoapUI, to my knowledge. When working with critical cases or the, we were not able to group them properly. We can definitely create a suite and add them there, but within a whole suite, we have to identify them, which was not easy."
"The UI could be a bit more flexible."
"In the LoadUI companion the scripts are not user friendly, and it also has a slow startup time."
"There aren't any plugins for UI automation. You need to make a custom code and download a job to put into the libraries. If it were panelized, then it would be straightforward. It should be in a panel of the tools, so you can add those tools as your test step in your test cases."
"There are no bugs or glitches, but a few features available only in the Pro version could be made available in the open-source version. Some of the features do not necessarily need to be only available to Pro users. The data generator would be really useful for the open-source version users."
"The application has to be restarted after being used for an hour or so as it stops working after that."
"The tools that are stated by SmartBear speaks for itself, but when it comes to improvements, there could be a release which only aims for the development of beginners in terms of understanding the tools that are laid by SmartBear."
"Mobile application testing would be helpful for us."
"LambdaTest's technical support comes in different tiers - most issues get resolved, but there's room for improvement with critical issues."
"Sometimes, when multiple users use the tool simultaneously, it can slow down, affecting efficiency."
"It would be much easier for us to read the test if they provided dashboard analytics."
"The tool can improve its testing speed. Changing or switching to another mobile phone can be very slow on a real device."
"I would like to see all of the features available in the freemium plan so that I can test them."
"Load flow compared to other stacks 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."
 

Pricing and Cost Advice

"I think the number of users is also limited, considering how much we pay."
"ReadyAPI Test is about $680 per user, per year."
"ReadyAPI Test is expensive, and I rate its pricing a four out of ten."
"It is free of charge."
"My understanding is that the pricing is okay, however, that's taken care of by our procurement team. It's around $5,000 for three years."
"The Pro version can be expensive for some companies. There are no costs in addition to the licensing fees."
"SoapUI Pro is open source but it has a subscription-based model which involves some more features. At the moment we are using the free version. The Pro version requires a license, and it is an annual license to use it."
"The cost is not that bad."
"It is free to start, which means you can actually see how it works and then take the decision to buy."
"The pricing could be made cheaper."
"This is an affordable product."
"The product can be described as an averagely-priced solution."
"From the customer side, LambdaTest is cheaper for big company usage and works fine as other similar applications."
"It is 60% cheaper and there is no fuss in maintaining the lab, so we have more time to do the testing."
"LambdaTest is priced well, which is why we migrated to it."
"I used the product for free."
