I am new to Jasmine2 JS framework. I am using Jasmine.js framework to create test suites for my application developed in Backbone.js framework.
When I am creating test cases for Backbone.js -> views home.js file, one of my home.js views function has
event.stopPropagation();
and another function has
event.preventDefault();
If my Backbone.js -> views function has event.stopPropagation(); and event.preventDefault();, my test suites throws error as below:
TypeError: Cannot read property 'stopPropagation' of undefined
Please help me, how to write a test cases for my views function which has event.stopPropagation(); and event.preventDefault();
or
how to skip these has event.stopPropagation(); and event.preventDefault(); when I am calling function from Jasmine.js framework?
Kindly let me know, If you need any further clarification from my transition.
Thanks in advance.
You can try this code, I hope this works for you to test events:
var event = {
type: 'click',
stopPropagation: function () {},
preventDefault: function () {}
};
var stopPropagationSpy = spyOn(event, 'stopPropagation');
var preventDefaultSpy = spyOn(event, 'preventDefault');
{OBJ}.{FUNCTION_TO_CALL}(event);
$("{YOUR_ELEMENT_TO_TRIGGER}").trigger(event);
expect(stopPropagationSpy).toHaveBeenCalledWith();
expect(preventDefaultSpy).toHaveBeenCalledWith();
