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 most valuable feature has been the assertion as a test step as this has allowed us to increase the scope of testing and validation."
"It's easy to implement."
"The performance testing capabilities are very good."
"The dashboards are very good and consolidate all of the tests that you are performing with the client."
"The most valuable features of ReadyAPI are the scripting tools and the connectivity to external data sources, such as Excel and PDF files. There are plenty of useful features that are useful, such as automating flexibility and usability. Overall, the solution is easy to use."
"The two most valuable features we use are the functional test and the security test."
"The main advantage is that it could be integrated into different CI/CD tools, and that is something that is really valuable and helpful."
"ReadyAPI's best features are user-friendliness, smooth integration with Postman, the speed of creating test cases, and integration with customer data."
"We are happy with the technical support."
"But for now, we are happy with what have been using."
"The most powerful aspect is the ease of use."
"SmartBear LoadNinja is easy to use and implement."
"It's a very simple tool for performance testing."
 

Cons

"I think the security testing with API could be improved as they provide limited templates."
"I would not recommend this product, as there are better products out there."
"The content on ReadyAPI in SmartBear Academy is outdated."
"One issue I found with ReadyAPI is related to event listeners compared to JMeter or SoapUI. We created an in-house dashboard to display automation runs across projects, which required manual updating of event listeners for new project imports."
"We have an older version of ReadyAPI and it's not supporting our whole tests, so we have had to migrate some or we've had difficulties running them because they're very old script."
"In terms of features, I have already raised different change requests on the ReadyAPI side. One of the largest functions I've requested is the validation of the payload for the REST APIs."
"ReadyAPI could improve by having dynamic validation information."
"Based on my experience, ReadyAPI could improve by simplifying the process of scripting."
"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

"This is a cheap solution when you consider the money that will be saved in testing."
"For each license, they charge the same amount, which is less than $1,000 for each desktop license."
"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."
"The thing with ReadyAPI is that you have to buy different licenses for different purposes."
"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 solution is dynamically priced so you only pay for what you use."
"The pricing is very competitive."
"Certainly, the cost could be reduced."
