Featured Reviews

Walter Wirch - PeerSpot reviewer
Seamless integration with cloud environments supports backend projects while seeking AWS Lambda enhancements
ReadyAPI enhances my workflows by allowing us to use Docker containers based on the ReadyAPI test runner. It helps extend our functional tests, even though we are not heavily using performance testing. It supports a wide range of protocols such as Kafka and GRPC, depending on the project. It also aids in faster feedback to developers, allowing them to implement developments in a sprint without the need for extensive testing afterwards, thus improving our time to market metrics.
Shiju Chandran - PeerSpot reviewer
Good performance testing, simple UI, and the ability to run the same script across different domains
StresStimulus simulates browser HTTP calls. I would love to see where it can also simulate a real browser to measure visually complete time. For example, to be something similar to TruClient. 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. In a world where the applications are changing every day, I hope StresStimulus comes up with an option to compare HTTP requests before and after deployment and tell me what requests have changed. This would help avoid rescripting every time, and this would be a huge deal.

Quotes from Members

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

Pros

"ReadyAPI's best features are that it's user-friendly and its behavior-driven development is flexible."
"It is the best solution you can get across the globe for API, test automation, and API penetration testing."
"It can create stress tests very fast, and some features help you do it fast."
"ReadyAPI's best features are user-friendliness, smooth integration with Postman, the speed of creating test cases, and integration with customer data."
"The most valuable features of ReadyAPI are the ready-to-use assertions and filters which can perform the validation. If we want to filter out any value, the filters are available. Apart from that database integration, if you want to go ahead and perform validation in the database layer it is possible with the ready-to-use feature available. The execution and reporting are rich features."
"The most valuable features of ReadyAPI are its robust functionality and collaboration capabilities."
"It has the ability to combine it with different CI/CD tools."
"The interface is ok and they have the ability to re-load tests so that you can reuse them."
"Technical support is great."
"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."
"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

"Based on my experience, ReadyAPI could improve by simplifying the process of scripting."
"ReadyAPI could improve by having dynamic validation information."
"The performance in some cases needs improvement. Sometimes it requires too many resources."
"Currently, we don't extensively use the performance testing due to license costs. License prices can be a factor in considering which technologies to adopt."
"The UI should be flexible. Currently, the UI isn't."
"The overall scope of this solution is limited and could be improved."
"There are lots of options within the solution, however they are not upfront or user-friendly."
"Areas for improvement include the security files, endpoints, and process sessions."
"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."
 

Pricing and Cost Advice

"We pay $3,000 annually for a floating license. actually. That allows another person from my company to use it as well. It's a cloud-based license."
"The thing with ReadyAPI is that you have to buy different licenses for different purposes."
"If I remember correctly, ReadyAPI costs between $5,000 to $7,000 for five thousand virtual users running it at a given point in time. Other tools, for example, Apache JMeter, can run millions of users at a given time. ReadyAPI is a tool that requires you to pay more money if you want more users to run it for performance testing. For functional testing, each ReadyAPI license costs $1,000, and you do get basic testing, and it's inclusive of one hundred users. In my company, if there's a need for more than one hundred users, my team uses Apache JMeter because it's futile to end up paying $5,000 or $6,000 annually just for performance testing, which can be done in Apache JMeter as well. Given the circumstances, my team does performance testing only towards the end of the fiscal year when the regulatory testing of applications takes place. If I have to run ReadyAPI just for two days or just for ten or fifteen odd days, then it's not worth paying $5,000 for the license with the small number of users provided by ReadyAPI."
"We use fixed licenses, and the last time I checked, I want to say it's around $680 per seat per year."
"It costs approximately $200 000 Taiwan Dollars for three years."
"The price was around $6,000 for one license, but I don't remember exactly. It is definitely expensive. Our organization was planning on having multiple licenses for this year."
"The price of the solution has been fine."
"For each license, they charge the same amount, which is less than $1,000 for each desktop license."
