mock-cpu-length
Mock os.cpus().length in CI env(!!process.env.CI === true). It often gets wrong CPU core length when using os.cpus().length in some CI environments due to containerized technology such as CPU share. It would affect how many child processes should be forked/spawned and cause huge performance issue in Node.js.
Usage
Notice: This package only has impact in CI.
const os = require('os');
const { mockCPULength, resetCPULength } = require('mock-cpu-length');
process.env.CI = true;
mockCPULength(2);
console.log(os.cpus().length); // print `2`
mockCPULength(3);
console.log(os.cpus().length); // print `3`
resetCPULength();
console.log(os.cpus().length); // print the actual CPU cores numberLicense
