Testing

1. Create a workflow with one script able task that has the following code:

var __global = System.getContext() || (function () { return this; }).call(null);
var VROES = __global.__VROES || (__global.__VROES = System.getModule("com.vmware.pscoe.library.ecmascript").VROES()), exports = {};

var array1 = array1 = VROES.Shims.arrayFrom({ length: 5 });
System.log("Array 1  data: " + JSON.stringify(array1, null, 4));

var arr = [{ key1: 1 }, { key2: 2 }, 3, "ddd"];
var array2 = VROES.Shims.arrayFrom(arr);
System.log("Array 2  data: " + JSON.stringify(array2, null, 4));

2. Run the workflow, the output should be array based on the input object.
