Apache JMeter vs Loader.io: What are the differences?
Introduction
Apache JMeter and Loader.io are both tools used for performance testing, but they have some key differences that set them apart.
Purposes: Apache JMeter is a versatile tool used for load and performance testing of both static and dynamic resources. It can simulate heavy loads on servers, network or objects, and can perform functional testing as well. On the other hand, Loader.io is a cloud-based load testing framework specifically designed for web applications and APIs. It helps to measure the application's performance and identify potential bottlenecks under heavy loads.
Testing Approach: Apache JMeter follows a black-box testing approach as it does not require access to the source code or internal structure of the application being tested. It is capable of simulating different network protocols, recording user scenarios, and replaying them. Loader.io follows a white-box testing approach, where the application's code structure and internal workings are available. It allows the users to write custom JavaScript test scripts to simulate real user interactions.
Scalability: Apache JMeter is a desktop-based application, and its scalability depends on the hardware and resources of the machine on which it is installed. In contrast, Loader.io is a cloud-based service provided by SendGrid, which can scale up to handle large loads by leveraging its cloud infrastructure. It can distribute load tests across multiple servers and locations with ease, allowing for higher scalability.
User Interface: Apache JMeter has a rich desktop-based graphical user interface (GUI) that allows testers to create and manage test plans easily. It provides a wide range of built-in components and functions that can be used to design complex test scenarios. Loader.io, on the other hand, provides a web-based user interface that is intuitive and easy to use. It offers a simple and straightforward way to create and execute load tests without the need for any installation or setup.
Cost: Apache JMeter is an open-source tool and is available for free to users. It can be downloaded, installed, and used without any additional cost. Loader.io, on the other hand, is a commercial service provided by SendGrid, and it offers different pricing plans based on the number of concurrent users and the duration of the load tests. The cost of using Loader.io varies depending on the specific testing requirements.
Integration: Apache JMeter provides extensive integration capabilities with other tools and technologies. It can be easily integrated with frameworks like Selenium for web application testing or with CI/CD pipelines for incorporating load testing as part of the development process. Loader.io offers integrations with popular platforms like Heroku, AWS, and Docker, allowing users to incorporate load testing into their existing workflows seamlessly.
In summary, Apache JMeter is a versatile desktop-based tool that supports various protocols and is suitable for both load and functional testing. On the other hand, Loader.io is a cloud-based load testing framework specifically designed for web applications and APIs, offering convenience, scalability, and a user-friendly interface.
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.
If you have questions or need help, you can ask on Slack and the Community forum.
