Principles of perfect testing

A testing manifesto

The perfect test is concise, unambiguous, safe, with easily understandable logging.

• It is named to concatenate

jimhigson

import {setTimeout} from 'node:timers/promises';

const root2 = 2**0.5;

const circ = (r) => {

  const rr = Math.round(r);

  const buff = Array(rr*2+1).fill(0).map(_ => (Array(rr*2+1).fill(' ')));
