Mock any executable binary
Useful for mocking tests that run executable binary, especially to fake edge cases and increase test coverage.
$ npm install --save-dev mock-bin
const mockBin = require('mock-bin');
const log = 'mocking git!';
const unmock = await mockBin('git', 'node', `console.log('${log}')`);
let actual = shell.exec('git').stdout;
t.is(log + '\n', actual);
unmock();
actual = shell.exec('git').stdout;
t.not(log + '\n', actual);Returns a promise which resolves with an unmock() function.
