Experience effective testing with flexible licensing alongside pivotal insights on essential improvements
For non-functional testing, I focus on performance and security. For performance and security tests, I used REST API, SoapUI, and JMeter. These tools help us conduct thorough testing across these dimensions. I find ReadyAPI helpful especially in overcoming security issues, as we experienced slowness in the application after merging our JAR files. For instance, if a person wants to access a university database and encounters a timeout error, we learned through ReadyAPI that the issue was due to HTML protocol limits with the payload. We fine-tuned this process to display the expected data effectively. I consider ReadyAPI a cost-effective solution because it covers three verticals without needing to purchase separate tools for security, performance, or functional testing. ReadyAPI is a versatile tool for creating multiple testing frameworks and validating various parameters seamlessly. REST API is the tool I use to test all three types of articles, meaning I validate the APIs I send to my peers or clients for functional testing, and I also perform security testing to ensure the URL and data passed through multiple components adhere to policies and user privileges. This is done through functional security testing using the REST API tool, and for performance, I ensure that applications can be accessed simultaneously by multiple users without hindrance or slowness through thorough performance testing.

Easy to use with good documentation and helpful support
It's a new tool when I compare it with LoadViewer and HP LoadRunner. It needs time to mature. For example, it needs to improve concurrency. When you run a test suite, your scripts will generate some test data. If we are running a banking application and then we are running a full end-to-end suite, there are many actions that need testing. There's a lot of data getting generated. There should be a variable that we can store for later in our later test cases. We need data management and dynamic data generation to be able to capture the data which is generated.

Quotes from Members

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

Pros

"The initial setup is straightforward."
"For anyone who does not have experience with automation, ReadyAPI provides a sense of comfort, especially for testers who find it hard to go directly into coding."
"I would recommend ReadyAPI to others because it's user-friendly and can handle enterprise-level API testing needs."
"It has the ability to combine it with different CI/CD tools."
"With this solution, we have achieved a fifty-percent gain when it comes to writing test cases."
"It is the best tool that I have ever seen for API testing."
"It is very good from an integrative solution standpoint."
"Technical support from SmartBear is commendable."
"It's a very simple tool for performance testing."
"We are happy with the technical support."
"But for now, we are happy with what have been using."
"SmartBear LoadNinja is easy to use and implement."
"The most powerful aspect is the ease of use."
 

Cons

"The overall scope of this solution is limited and could be improved."
"Advanced functionalities could be improved."
"I would not recommend this product, as there are better products out there."
"The UI should be flexible. Currently, the UI isn't."
"The reporting is not very robust and needs to be improved."
"Lacking flexibility of adding more custom verification for security testing."
"Sometimes, if I changed something in ReadyAPI, it would not quickly pick up the change. It used to give me the same error repeatedly, and when I closed the application completely and restarted it, it would pick up that change."
"Version control does not work well."
"Certainly, the cost could be reduced. It requires attention. Clients have expressed dissatisfaction with the price."
"As we ran the test, we couldn't see the real-time results of how the solution behaved for 200 to 400 virtual users."
"It needs time to mature."
"On a smaller scale, there will be no budget issues, but as we expand to a larger user base, I believe we will face some pricing challenges."
 

Pricing and Cost Advice

"For each license, they charge the same amount, which is less than $1,000 for each desktop license."
"The solution is dynamically priced so you only pay for what you use."
"This is a cheap solution when you consider the money that will be saved in testing."
"The cost of a license is probably around $1,000 to $2,000. Accounting is done by my leadership. I am more into implementations and making sure all things and processes are taken care of and the frameworks are maintained and managed."
"The pricing is very competitive."
"The price of the solution has been fine."
"ReadyAPI is moderately priced, with added costs for more plugins."
"We use fixed licenses, and the last time I checked, I want to say it's around $680 per seat per year."
"Certainly, the cost could be reduced."
