BlazeMeter vs Loader.io: What are the differences?
Developers describe BlazeMeter as "The Load Testing Platform for Developers". Simulate any user scenario for webapps, websites, mobile apps or web services. 100% Apache JMeter compatible. Scalable from 1 to 1,000,000+ concurrent users.
. On the other hand, Loader.io is detailed as "Simple Cloud-based Load Testing". Loader.io is a free load testing service that allows you to stress test
your web-apps/apis with thousands of concurrent connections.
BlazeMeter and Loader.io belong to "Load and Performance Testing" category of the tech stack.
"I can run load tests without needing JMeter scripts. " is the top reason why over 7 developers like BlazeMeter, while over 5 developers mention "Easy to use" as the leading cause for choosing Loader.io.
OpenLabel, DocEngage, and CybrHome are some of the popular companies that use Loader.io, whereas BlazeMeter is used by MIT, Stormpath, and Day Delegate Limited. Loader.io has a broader approval, being mentioned in 14 company stacks & 8 developers stacks; compared to BlazeMeter, which is listed in 6 company stacks and 3 developer stacks.
Kindly suggest the best tool for generating 10Mn+ concurrent user load. The tool must support MQTT traffic, REST API, support to interfaces such as Kafka, websockets, persistence HTTP connection, auth type support to assess the support /coverage.
The tool can be integrated into CI pipelines like Azure Pipelines, GitHub, and Jenkins.
RedLine13JMeter is best suited for generating user load with built-in integrations. To generate that type of load, you’ll need to choose a cloud-based solution that runs JMeter, such as BlazeMeter or RedLine13. They support JMeter for testing RESTful APIs and there is a plugin specifically designed for MQTT. You’ll want to look at subscription options and costs to run at that great a load.
There are JMeter plugins you can configure for all sorts of profiling including persistence of connections. And third-party plugins that you can add as JAR files to your load test, such as this one specifically for Kafka. JMeter also has good support for configuring authorization headers.
With regard to CI/CD integration, both support Jenkins. RedLine13 has a custom Jenkins plugin and allows for resources for tests to be sourced from GitHub and other places like AWS S3.
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)
k6Disclaimer: 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.
