We are currently tasked with testing a function that determines the top position of an element. Specifically, we need to evaluate the top position of an element with the ID 'test'.
function findTopPosition(){
var targetElement = $('#test');
return targetElement[0].getBoundingClientRect().top;
}
As part of our testing process using Jasmine, we attempted the following approach:
var mockedObject = {
name: 'test',
getBoundingClientRect: function () {
return {top: 100}
}
}
spyOn($('#test'), 'getBoundingClientRect').and.returnValue([mockedObject]);
However, this resulted in an error message:
Error: <spyOn> : getBoundingClientRect() method does not exist
Usage: spyOn(<object>, <methodName>) (line 4740)
