Apache JMeter vs LoadNinja: What are the differences?
Introduction Apache JMeter and LoadNinja are both performance testing tools used to measure the performance and load capabilities of web applications. While they share similarities in terms of their purpose, there are key differences between the two tools.
Architecture: Apache JMeter is a desktop application that can be installed on various operating systems and requires the user to manually set up and configure test scenarios. On the other hand, LoadNinja is a cloud-based solution that provides a web-based interface for setting up and running performance tests, eliminating the need for local installation and configuration.
Scripting Capabilities: Apache JMeter relies heavily on manual scripting for creating test scenarios and requires the user to have programming skills. It uses a scripting language called JavaSampler for creating custom test cases. In contrast, LoadNinja offers a scriptless approach where users can record their interactions with the application and automatically generate test scripts, making it more accessible to non-technical users.
Real Browser Testing: LoadNinja offers the ability to perform real browser testing by leveraging a real web browser for executing test scenarios. This allows for more accurate simulation of user interactions, including rendering and JavaScript execution. Apache JMeter, on the other hand, does not have built-in support for real browser testing and relies on simulated HTTP requests.
Collaboration and Reporting: LoadNinja provides features for team collaboration, including the ability to share test scenarios, collaborate on test scripts, and generate detailed reports. Apache JMeter, being a desktop application, lacks these collaboration features and requires manual effort for sharing and analyzing test results.
Scalability and Load Generation: LoadNinja is designed to scale up and generate high loads by leveraging multiple cloud-based servers. It offers easy scalability and distributed load generation capabilities, making it suitable for testing large-scale applications. Apache JMeter, although capable of generating load, may require additional infrastructure setup and configuration to achieve high scalability.
Pricing Model: Apache JMeter is an open-source tool and is available for free, making it a cost-effective option for performance testing. LoadNinja, on the other hand, is a commercial tool that requires a subscription, which may be a consideration for organizations with budget constraints.
In Summary, Apache JMeter and LoadNinja differ in terms of their architecture, scripting capabilities, real browser testing, collaboration and reporting features, scalability and load generation abilities, as well as their pricing models.
I have a team that is not heavy on programming skills. I am looking for a load testing tool that is easy to use. Preferably, the tool should be a record and playback tool without much programming. Also, the tool should be able to test APIs apart from web-based applications. What tool should I opt for?
My choice would be Apache JMeter, It's free and opensource plus it comes with lots of plugins and extendability. Apache JMeter needs a small amount of a learning curve and a basic understanding of Network, Protocols (TCP/IP ports, HTTP(S) and REST/SOAP, etc.) for initial setup. But it doesn't require programming skills. it has a nice record and playback option. You can still carry on without the developer skillset if you follow these steps. 1. Take backup. 2. Start recording and interact with the application. 3. stop recording and save the test case. This will give you your test-bed, after this, after these steps, every time just do Restore from backup and then Playback and observer results.
If you have longer recordings then an understanding of how to modify the recorded scripts will come handy.
For some of the advanced features such as Configuring variables, implementing loops, throttling adding think time, and automating test scaling to the number of users will require good planning of test scenarios and a Developer experience but this is true for any tool (even loader.io)
Disclaimer: I work at k6, and I recommend you try our tool.
It might require some coding skills, but we support a few options to record a user session to autogenerate the load test. Read How to record a browser session with k6 OSS.
The k6 Cloud also supports recording a user session with a Browser Extension. Additionally, it provides a Test Builder UI to generate a load test for testing APIs.
