Object method mocking.

process.nextTick(callback.bind(null, null, 'file contents here'));
});
`
Object props mocking with setter/getter.
`js
const muk = require('muk-prop');
const obj = { _a: 1 };
muk(obj, 'a', {
set: (val) => obj._a = val * 2,
get: (val) => obj._a,
});
obj.a = 2;
console.log(obj.a); // 4
`
Check if member has been mocked.
`js`
muk.isMocked(fs, 'readFile'); // true
Restore all mocked methods/props after tests.
`js
muk.restore();
fs.readFile(file, (err, data) => {
// will actually read from file
});
npm install muk-prop
`bash``
npm test
