What k6 does not
Does not run in a browser
As a result, k6 does not render webpages the same way a browser does. This also means that libraries relying on browser APIs won't be compatible. By skipping the browser, the consumption of system resources are dramatically decreased, making the tool significantly more performant.
Does not run in NodeJS
If you want to import npm modules or libraries using NodeJS APIs, you can bundle npm modules with webpack and import them in your tests.
