# vitals-tester
small utility to generate the vitals you want.
http://vitals-tester.vercel.app/
### General
Every metric supports categories (GOOD, POOR, NEEDS_IMPROVEMENT) which will randomly pick a value to match that category.
Or numerical values with optional random parameters. So ?lcp=1000 sets the lcp to 1000, ?lcp=1000&random=500 sets the lcp
to some value between 500 and 1500. lcp?=GOOD sets it to a randomly picked "GOOD" value for the metric.
type={DESKTOP|MOBILE} set mobile or desktop thresholds when using categorical values (GOOD, POOR, NEEDS_IMPROVEMENT)
random=Number set a random fluctuation of +/-Number
### LCP and FCP can be used together or individually

https://vitals-tester.vercel.app/?fcp=500&lcp=1000&random=500
