Jasmine 2.0 Test With A Custom Matcher Fails: Undefined Is Not A Function

I have this function in my source file: function gimmeANumber(){ var x = 4; return x; } And a spec borrowed from this tutorial describe('Hello world', function() { be

Solution 1:

The API for adding custom matchers has changed since 1.3. You can see the changes here.

Here is how it works now:

functiongimmeANumber() {
    var x = 4;
    return x;
}

describe('Hello world', function () {

    beforeEach(function () {
        jasmine.addMatchers({
            toBeDivisibleByTwo: function () {
                return {
                    compare: function (actual, expected) {
                        return {
                            pass: (actual % 2) === 0
                        };
                    }
                };
            }
        });
    });

    it('is divisible by 2', function () {
        expect(gimmeANumber()).toBeDivisibleByTwo();
        expect(5).not.toBeDivisibleByTwo();
    });

});
