What is the simplest way to compare two arrays in QUnit

Question

I'm writing JavaScript unit tests (with the QUnit library). I need to verify that my array contains 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() in lieu of equal(). That will compare array elements and object properties, not just use the == comparison operator, which evaluates to false for objects that don't share the same constructor.
