Easy to set up with good documentation and easy management of testing cycles
The solution allows for a complete test cycle. The management of testing cycles are easy. We have good control over test cases. We can capture functional testing very easily. We're actually able to accelerate testing now and have end-to-end cycles for testing. We didn't used to have these capabilities. It's easy to automate and accelerate testing. The product offers very good cross-browser testing capabilities. We can do continuous testing and regression testing.

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.

Quotes from Members

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

Pros

"The major thing it has helped with is to reduce the workload on testing activities."
"The major thing it has helped with is to reduce the workload on testing activities."
"The OCR recognition is great, way over Sikulix or Robot Framework."
"The solution is user-friendly with respect to automation."
"It is a fine product; it is a powerful tool, and it needs commitment."
"Scripting is the most valuable. We are able to record and then go in and modify the script that it creates. It has a lot of generative scripts."
"The statistics that are available are very good."
"SilkTest is best for desktop applications and good for web applications also with the Open agent."
"ReadyAPI is a QA testing tool, and we were able to catch many bugs because we could inject various scenarios running through our data-driven testing, which improves the quality of our products."
"The two most valuable features we use are the functional test and the security test."
"It is the best solution you can get across the globe for API, test automation, and API penetration testing."
"ReadyAPI solves different business problems, and I've seen that, particularly in the education sector where I worked."
"Reporting is more robust than other products because test reports can be exported in multiple ways."
"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."
"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 most valuable features of ReadyAPI are the drag-and-drop options and the integration with versioning tool solutions, such as Git."
 

Cons

"Everything is very manual. It's up to us to find out exactly what the issues are."
"The support for automation with iOS applications can be better."
"We moved to Ranorex because the solution did not easily scale, and we could not find good and short term third-party help."
"Could be more user-friendly on the installation and configuration side."
"They should extend some of the functions that are a bit clunky and improve the integration."
"I've seen a lot of potential users upset with the SilkTest due to broken installation."
"We moved to Ranorex because the solution did not easily scale, and we could not find good and short term third-party help. We needed to have a bigger pool of third-party contractors that we could draw on for specific implementations. Silk didn't have that, and we found what we needed for Ranorex here in the Houston area. It would be good if there is more community support. I don't know if Silk runs a user conference once a year and how they set up partners. We need to be able to talk to somebody more than just on the phone. It really comes right down to that. The generated automated script was highly dependent upon screen position and other keys that were not as robust as we wanted. We found the automated script generated by Ranorex and the other key information about a specific data point to be more robust. It handled the transition better when we moved from computer to computer and from one size of the application to the other size. When we restarted Silk, we typically had to recalibrate screen elements within the script. Ranorex also has some of these same issues, but when we restart, it typically is faster, which is important."
"The browser based testing needs to be improved."
"The UI should be flexible. Currently, the UI isn't."
"ReadyAPI could improve by having dynamic validation information."
"The reporting is not very robust and needs to be improved."
"The initial setup could be less complex."
"What needs improvement in ReadyAPI is its load testing feature because there was a hiccup when my team performed some load testing on the tool. My team had meetings with the ReadyAPI team and tried to get that issue fixed, but it still hasn't improved. This is a shortcoming of the tool, especially when you compare it with HP LoadRunner."
"It doesn't have connectors to the NoSQL database. This is one of the things where they do not have a very solid strategy today."
"We stopped using this solution because of issues with scalability. Performance and memory management both need to be improved because other solutions use less memory for the same amount of data."
"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."
 

Pricing and Cost Advice

"We paid annually. There is a purchase cost, and then there is an ongoing maintenance fee."
"Our licensing fees are on a yearly basis, and while I think that the price is quite reasonable I am not allowed to share those details."
"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."
"For each license, they charge the same amount, which is less than $1,000 for each desktop license."
"The thing with ReadyAPI is that you have to buy different licenses for different purposes."
"We use fixed licenses, and the last time I checked, I want to say it's around $680 per seat per year."
"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."
"We have approximately 12 licenses in place. There are other solutions that are more expensive than ReadyAPI that have more features, but if the scope of the project is limited to SOAP and REST service, then this is the best option."
"This is a cheap solution when you consider the money that will be saved in testing."
