I'm not able to cover the handler being executed while writing test cases using Jasmine Karma

Question

I am new in writing test cases using Jasmine and Karma.

This is the piece of code I'm trying to cover.

oncreate: () => addWindowResizeListener(() => this._resizeHandler())

Below is the line referring to the above in my spec file

expect(contentPanelFooterBodyVDOM.getAttr("oncreate")).toEqual(Function)

The code coverage is shown as below

How can I attain complete code coverage?

Answer 1

I don't see your code coverage but you have to actually call your function to get code coverage.

// spy on the function to be called.
spyOn(something, '_resizeHandler');
// call the function
something.oncreate();
// expect for it to be called
expect(something._resizeHandler).toHaveBeenCalled();
