What is the easiest way to compare two arrays in QUnit

Question

I am writing JavaScript block tests (with the QUnit library). I need to verify that my array contains the expected (and only) elements.

var array = getArrayFunction(a, b); equal(["one", "two", "three"], array, "Test is failing even if 'array' contains needed elements"); 

What would be the easiest way to do this?

Answer 1

You should use deepEqual() instead of equal() . This will compare the array elements and the properties of the object, and not just use the comparison operator == , which evaluates to false for objects that do not have the same constructor.
