How to write test for confirm dialog

[Quazi Marufur Rahman]

Hi,

I have written a code snippet which will show a alert box if there is any text in an input field 

and a user tries to reload the page or redirect to another page.

Here is the code.

I want to write a test for this scenario using Jasmine. I have written a test, but it always fails. 

Here is the test.

Please help me to find the problem. No confirm box is creating during simulation. Why this fails and how to solve this issue?

Thanks in advance.

Mocking window.confirm:
window.confirm = function(msg){
     //return false to simulate the Cancel button having been clicked, or true to simulate the OK button having been clicked
     return false;
};

I would split it up into two suites. Test that your event handler is
bound to the window events by using a spy, and test that your event
handler does what it's supposed to by calling it directly.

describe('beforeunload', function() {
it('should trigger warning', function() {
spyOn(someObject, '_unsavedPublisherWarning');
$(window).trigger('beforeunload');
expect(someObject._unsavedPublisherWarning).toHaveBeenCalled();
});
});

describe('someObject._unsavedPublisherWarning', function() {
describe('when input exists', function() {
beforeEach(function() {
someObject.el_input.val('whatever');
});
it('should return a warning', function() {
expect(someObject._unsavedPublisherWarning()).toBe('navigation_warning');
});
});
describe('when no input exists', function() {
beforeEach(function() {
someObject.el_input.val('');
});
it('should not return a warning', function() {
expect(someObject._unsavedPublisherWarning()).not.toBeDefined();
});
});
});
