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.

Reliable with excellent support but needs better source control integration and versioning
Source control integration and versioning could be better. Currently, StresStimulus does not natively support any form of change control management. Result analysis (snap-out tabs for side-by-side comparisons) need improvement. Multiple sets of analysis results can be opened in the user interface at the same time, and comparison reports can be generated to compare some aspects of pairs of test runs. However, the interface that displays the multiple sets of results only allows a single result set to be viewed at any one time & uses tabs to switch between the individual result sets. It would be useful to have the ability to view multiple tabs at once, either side by side in the interface or by snapping tabs out of the interface into their own windows to be viewed together with others. Graphing (collect PerfMon data as part of the tests and then have the ability to create different graphs with that data after the test completes to help with analysis) could be better. Graphs and their contents have to be defined before tests are run. Often, as a result of running tests and viewing the results collected, it is necessary to have graphs showing/comparing different metrics collections than those specified before the run. Other tools collect metrics that are not tied to pre-defined graphs & allow the metrics to be used to construct graphs as required by subsequent analysis & investigation. Nested tests/test case groups/test solution files (ability to build a hierarchy of test cases/test case groups/solution files) are required. Within a StresStimulus, tests are organized in just two levels, test cases, and test case groups. As is possible with other tools, it would be helpful to have a hierarchy with multiple levels of nested test cases/test case groups (or even the solution config files themselves). It would make it easier to manage multiple sets, combinations of tests, load profiles & test mixes if a high-level solution file (or test case group) could run a collection of lower-level ones, which in turn end up executing multiple different base-level test case groups and individual test cases.

Quotes from Members

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

Pros

"When the scripts are stable, Perfecto is awesome."
"Overall, it results in huge cost savings for our company."
"The reporting feature is really tough to find in some of the other products that are competitors. Having your CITB type dashboard, where we can see the test results and see recordings of each test that passed or failed, is probably one of the distinguishing aspects of Perfecto."
"We are continuously doing testing on different environments, devices, and platforms. It executes seamlessly on multiple devices without having any connectivity issues. It has been really helpful for us to test on cloud devices."
"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."
"Customer Service: It's been 100%. Technical Support: It's been 100%."
"The Perfecto device lab has allowed us to run tests on multiple devices at the same time and across multiple platforms as well, increasing the efficiency of our testing and saving money, time, and effort while enabling comprehensive testing and high app quality that we otherwise wouldn't be able to achieve."
"Overall, it's a great solution."
"Compared to other tools, there is not a whole lot to Stress Stimulus UI. This makes it easy to use, be it while scripting, executing, or having to train someone new to the team."
"Technical support is great."
"Designed to be a modern testing tool, StresStimulus made it easy for us to upgrade from an older deprecated testing tool and adapt to Agile DevOps testing principles by shifting left with performance testing."
 

Cons

"When using devices on the cloud, it lags quite a bit at times."
"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."
"The monitoring features, in particular network traffic monitoring, could be improved."
"On the analytics side, Perfecto is in need of improvement."
"I'm hoping that Perfecto will come up with browser testing as well because it would be easier to access it."
"In iOS, it needs improvements with some limitations."
"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."
"The flakiness, or the accuracy, of the test execution can be improved. Also, the responsiveness of their cloud lab could be improved as well."
"We run tests on SQL statements and stored procedures directly, even before integrating with UI. I wish there were a way to connect to my application DB and run SQL queries using a JDBC connection."
"Result analysis (snap-out tabs for side-by-side comparisons) need improvement."
"StresStimulus has a dedicated blog where users of the tool can log new feature requests or enhancements to existing features."
"Analyzing results from test runs is proving to be challenging."
 

Pricing and Cost Advice

"This is an expensive solution compared to others, by 30% to 40%."
"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 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."
"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'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."
"Pricing is an area where Perfecto can do a little better. When we obtain additional licenses, we enter into negotiations with them."
