Allows you to parameterize in one place for the changes to reflect everywhere and lets you customize the environment, but its load testing feature needs improvement, and costs need to be cheaper
One of the features of ReadyAPI that's worth mentioning is that it allows you to parameterize. I'm working with more than two hundred resources, so I don't have to go and make a small change at each point every time. I have the option to just parameterize in one place for the changes to reflect everywhere. Another valuable feature of ReadyAPI is that it provides a customized environment. In my company, you work in different environments, such as QA, UAT, and LT, so the URLs for every environment are different. In ReadyAPI, you can customize your environment, set it up, then start working on it. Another feature worth mentioning that's offered in ReadyAPI is automating your test value as the tool allows Groovy scripting. In your test case, you can use a Groovy script that says that in a particular test case, you have ten resources, but you just want to exhibit five and that you don't want to exhibit the remaining five. You can write a small Groovy script that lets you execute just five resources out of the ten resources. I also like that ReadyAPI allows you to read the data from CFC and Excel. It also allows you to create or customize your data, but that only works at a certain point because every application has its specific data. ReadyAPI cannot generate every data, but when I'm posting and I want to generate a random name, such as a first name, I can do it in ReadyAPI. The tool also has many different features which I find valuable, including Git integration.

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

"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."
"The most valuable feature is being able to run each version for test suites."
"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."
"When we are doing API testing we have found it to be very efficient to receive results. Additionally, you are able to do tests directly from the API."
"The performance testing capabilities are very good."
"The initial setup is straightforward."
"The most valuable features of ReadyAPI are the drag-and-drop options and the integration with versioning tool solutions, such as Git."
"The great thing about ReadyAPI is that it has a wide variety of functions. You can test any API that you come across. You are not limited to one type of API. It supports many APIs."
"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."
"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."
 

Cons

"It is challenging doing upgrades and patches because sometimes the environmental variables or suits in the projects get erased."
"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."
"Advanced functionalities could be improved."
"The UI should be flexible. Currently, the UI isn't."
"If ReadyAPI had more integration with all of the big tools on the market then this would be very useful."
"The UI is not user-friendly."
"Areas for improvement include the security files, endpoints, and process sessions."
"They have performance testing also. However, it's not that great."
"Result analysis (snap-out tabs for side-by-side comparisons) need improvement."
"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."
"StresStimulus has a dedicated blog where users of the tool can log new feature requests or enhancements to existing features."
 

Pricing and Cost Advice

"For each license, they charge the same amount, which is less than $1,000 for each desktop license."
"The pricing is very competitive."
"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."
"ReadyAPI is moderately priced, with added costs for more plugins."
"It costs approximately $200 000 Taiwan Dollars for three years."
"It is expensive. Each user needs to be licensed, and there are different licenses within the product. It starts with 750 euros for a single user per year, but for the full product features, you need to pay a lot more. There are three versions. This cost is for functional testing, and then there is a cost for load testing and virtual services. If you want to use these areas with the functional test license, you are limited. You hit some limits in these functions. If you have all three licenses, then you have full functionality for the API."
"The price of the solution has been fine."
"The thing with ReadyAPI is that you have to buy different licenses for different purposes."
