A simple should.js extension for testing approximate values for array-like things. Works like approximately, but with arrays. Usage: [9.3567, 1.23456, 1.11112].should.be.nearly([9.36, 1.24, 1.12], 0.01);

should.nearly.js

const should = require("should");
should.Assertion.add("nearly", function(arr, delta) {
	try {
		for(let i = 0, len = arr.length; i < len; i++) {
			this.obj[i].should.be.approximately(arr[i], delta);
		}
	}
	catch(e) {
		throw new Error("expected ["+this.obj.toString()+"] to be approximately ["+arr.toString()+"] ± "+delta);
	}
});
