Scalability Issues

Sentiment score
6.6
Apache JMeter is scalable but struggles with high loads, requiring distributed testing and complex configurations for extensive usage.
Sentiment score
6.8
ReadyAPI offers scalable API management for large operations, though cloud migration and flexibility improvements are needed for easier use.
This restricts the number of users and necessitates increasing load agents or distributing the script across multiple machines.
For backend automation and performance testing with web services, web APIs, and queue management systems, I would rate Apache JMeter's scalability as between eight and nine.
JMeter is highly scalable, easily handling increased loads through the use of multiple servers.
I rate ReadyAPI between five to six for scalability due to complexities associated with scripting.
ReadyAPI's performance testing capabilities can impact API scalability assessments.
 

Stability Issues

Sentiment score
7.2
Apache JMeter is generally stable and reliable but may require tuning for optimal performance under high load conditions.
Sentiment score
7.2
ReadyAPI offers stability with occasional bugs; users appreciate its reliability, especially post-configuration, aided by regular updates.
JMeter performs exceptionally well, especially in non-GUI mode, which supports high loads efficiently.
Several necessary features still need improvements, specifically in terms of reports and additional functionalities compared to other commercial tools.
Once all configurations and preparations are done, it is very stable.
 

Room For Improvement

Apache JMeter faces challenges with SSL recording, performance issues, complex scripting, limited support, and inadequate documentation.
ReadyAPI users seek improved integration, performance, UI, version control, scalability, cloud support, security testing, and automation capabilities.
Currently, we need to use multiple separate JMeter instances to simulate reductions in load, which isn't ideal.
Apache JMeter could be significantly enhanced by the integration of BDD frameworks.
Automating report analysis and supporting customized SLAs for script report generation could also enhance functionality.
I'm considering the use of AWS and its Lambda functionalities prepared by the vendor.
 

Setup Cost

Apache JMeter is a cost-effective, open-source tool for smaller projects, with community support; high-scale testing needs additional tools.
ReadyAPI offers flexible enterprise pricing from $1,000-$6,000 annually, cost-effective for functional testing and service virtualization.
Using JMeter helps us avoid additional costs for high-load testing since it is open-source and allows for unlimited virtual users at no extra cost.
It's a cost-effective solution.
Apache JMeter is completely free as it is open-source.
The pricing of ReadyAPI is reasonable, considering its functionality compared to other tools in the market.
Currently, we don't extensively use the performance testing due to license costs.
 

Valuable Features

Apache JMeter is a flexible, scalable, open-source tool for comprehensive performance testing with robust community support.
ReadyAPI simplifies API testing with CI/CD integration, scripting, tool compatibility, drag-and-drop, and robust reporting features.
Despite being open source, it offers features comparable to paid tools.
JMeter facilitates scripting capabilities, which include options for Groovy scripts.
Monetary benefits with Apache JMeter are notable since it doesn’t require a licensed version.
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.
ReadyAPI is valuable for web service automation and allowing us to generate test cases and automate processes.

Leveraging cost-effective customization with powerful plugins but complexity reduction needed
Apache JMeter offers plugins for reporting and preparing test scenarios. It allows recording to customization, letting you download plugins to connect with databases or external systems. Despite being open source, it offers features comparable to paid tools, and its ability to customize and expand is particularly useful. Additionally, its open-source nature makes it cost-effective.
SandeepSingh9 - PeerSpot reviewer
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.
