Qunit test property exists in object

I am using Qunit testing engine in JavaScript and I need to check if a property exists in an object.

Here is my setup:

 var tests = [
    {
        foo: 'foo',
        bar: 'bar',
        expected: {}
    },
    {
        foo: '',
        bar: '',
        expected: //I need to expect foo and bar properties to exist
    }
 ]

 for(var i = 0; i < tests.length; i++) {
    assert.deepEqual(validate_foo(tests[i]), tests[i].expected);
 }

The function validate_foo() either will return an empty object {} on success, or an object with the properties of each error. For example, validate_foo() expectes foo to equal foo and bar to equal bar. So in the second test, the result is:

{
    foo: 'foo does not equal foo',
    bar: 'bar does not equal bar'
}

How do I write a test to accomblish this?

Maybe I have totally missed the point, but assuming you are testing the validate_foo function, isn't this all you need to do?

var tests = [
    {
        foo: 'foo',
        bar: 'bar',
        expected: {}
    },
    {
        foo: '',
        bar: '',
        expected: {foo: 'foo does not equal foo',
                   bar: 'bar does not equal bar'}
    }
 ]

 for(var i = 0; i < tests.length; i++) {
    assert.deepEqual(validate_foo(tests[i]), tests[i].expected);
 }

...and if that's not the test you want then can you clarify what specifically you are trying to test in this case?
