I need some help to get my code coverage up. I have this function in my ts file and need to understand how to have this if statement execute.
setWidth(): void {
let maxHeight = 0;
document.querySelectorAll<HTMLElement>(`.body`).forEach(element => {
if (element.offsetHeight > maxHeight){
maxHeight = element.offsetHeight;
}
});
I am not clear on how I would get the forEach to execute in my spec.ts file.
Try this:
it('should set maxHeight', () => {
// set a spy and return a mocked array.
// add as any here below as well.
spyOn(document, 'querySelectorAll').and.returnValue([{ offsetHeight: 20 }] as any);
service.setWidth();
// below is a bad expectation but I am not sure what to expect for you from the
// code provided. Do an assertion that relates to setWidth.
expect(1).toBe(1);
});
