hrtimemock

hrtimemock is a mocking function that causes process.hrtime to output what ever time should have elapsed.

hrtimemock(mstime)

monkeypatches process.hrtime and for the second call returns the elapsed time specified by mstime in the familiar array form.

• mstime time in milliseconds

Example

var hrtimemock = require('hrtimemock');

hrtimemock(1000);

var a = process.hrtime();
var elapsed = process.hrtime(a);

console.log(elapsed); //will output [1,0]

Notice:

Works only for a pair of process.hrtime calls.
After that it has to be called again.
