Load and Performance Testing
The success of creating a load and performance testing culture will be dependent on various factors. It’s critical to choose a tool that fits the requirements of you/your team and will help you meet your goals.
This worksheet is intended to help guide you to create a proof of concept and stay focused on the core task. A proof of concept should be fairly narrow in focus to start and able to easily expand should you have the time. POCs fail when you try to do too much, too quickly.
The first step should be to define goals you have for your proof of concept. These goals should be both related to your systems and the proof of concept itself. It should be clear so that you can reflect and say to yourself “this is done!”. Feel free to answer the questions below or write your own:
1 - What are you specifically testing?
2 - What SLAs/SLOs do you currently have in place?
3 - Where are you testing?
4 - What do you want to achieve in this POC?
There are many cases where you will need to edit your test scripts to ensure proper functionality or just extend the realism.
|Source code||OSS, built in Go|
|Platform||Independent, can be run on Windows/Mac/Linux.|
|Distributed load generators||Load gens can be spun up on demand across 15+ AWS regions|
|Community||Active Slack and community forum. GitHub repo updated often|
|Recording/Traffic capture||HAR conversion supported, Chrome extension available in cloud|
|Conversion from other tools||Postman and JMeter converters available|
|Virtual Users||Each virtual user is a concurrent user. Virtual users can make multiple requests in parallel. Virtual Users execute test script|
|Script/test configuration||Can be controlled via command line flags, within an object in the script, or in a separate JSON file|
|Scenarios/Modularization||Test scripts can be modularized for organization. Virtual Users can complete different journeys programmatically|
|Protocols supported||HTTP(s) (including HTTP/2), websockets. gRPC planned in the future|
|Extensibility||Custom modules/libraries can be written. Existing libraries that don’t depend on browser APIs can be used. Possible to convert some Node modules using browserify|
|Cloud features||List of Cloud/SaaS features|
Use this section to define some milestones to help you progress. Here’s an example. Your timeline and steps will likely vary.
1 - Run initial test examples. Get familiar with k6 and the cloud service.
2 - Implement and run baseline tests. Configure your test to validate your SLA/SLOs.
3- Fix clear and obvious issues
4 - Run tests frequently. Integrate into CI or schedule tests to run nightly.
Use this section to write down conclusions you came to during testing, good, bad, or indifferent. These should be related to the tool, your systems, and experience. If you have lingering questions, write them down here so you can get answers later.
Don’t let uncertainty bog you down! We’ve helped many users get through just about everything when it comes to load testing websites and APIs. We are happy to share best practices, put another set of eyes on your code, direction of your performance testing automation, or even give some guidance with results. Just send us a note: email@example.com. Feel free to include this worksheet as it can help us guide you!
