A really simple console wrapper that only logs to stdout if process.env.NODE_ENV is set to anything different than test, so it does not pollute your test suite.
Works for any console method.
Made for node.js runtime.
npm install except-on-test-logger --save
process.env.NODE_ENV = 'test';
const logger = require('except-on-test-logger');
// this does not print to stdout
logger.log('hello');
process.env.NODE_ENV = 'production';
// this gets printed to to stdout
logger.log('hello');
