[SOLVED] Is there any QUnit assertion/function who test whether element in array or not

Is there any QUnit assertion/function who test whether element in array or not

I have an array of my expected output in my Qunit function.Now I want to test that Is my result of function is in this array or not.

var a =new array('abc','cde','efg','mgh');

Now my question is Is there any QUnit assertion/function that can do this for me ??

I know that by some JS coding i create a method to check this but i wanna be spefic to OUnit only !!!!

Solution

If you have JavaScript 1.6 you can use Array.indexOf

test("myFunction with expected value", function() {
    var expectedValues = ['abc','cde','efg','mgh'];
    ok(expectedValues.indexOf(myFunction()) !== -1, 'myFunction() should return an expected value');
});

If you want you can extend QUnit to support these kind of assertions:

QUnit.extend(QUnit, {
    inArray: function (actual, expectedValues, message) {
        ok(expectedValues.indexOf(actual) !== -1, message);
    }
});

Then you can use the this custom inArray() method in your tests:

test("myFunction with expected value", function() {
    var expectedValues = ['abc','cde','efg','mgh'];
    QUnit.inArray(myFunction(), expectedValues, 'myFunction() should return an expected value');
});

I created a jsFiddle to show both options.
