This course shows you how to run clear and reliable load tests with k6. You learn core ideas like virtual users, load stages, checks, and thresholds. You use each idea right away as you test a real REST API.
You also learn how to create custom metrics and add tags to your requests to make your reports easy to read. You use setup and teardown steps to prepare and clean your tests. You set performance SLAs that fail the test when the API is too slow.
What You Learn
You learn how k6 models load so you can test real traffic patterns. You see how to add checks that guard key parts of your API. You also learn how thresholds help you catch slow responses.
Work With Real API Tests
You write simple scripts that send requests to a real API. You read the results and adjust the test when you spot slow parts. You learn to track response times, error rates, and request flow.
Build Clear Test Reports
You add tags that group your requests. You track custom metrics that show the parts of the API that matter to you. These tools help you find issues fast.
Why k6 Matters
k6 is easy to script and runs fast. It gives you clear output and fits well in CI pipelines. This helps you test your API often and catch problems early.
Set Strong Performance Rules
You learn to set SLAs that fail the test when the API slows down. This keeps performance steady as your API grows. You use thresholds to enforce these rules in every test run.
