Jasmine spyOn not working for window function

I am trying to spyOn on window.alert.I had spied window's alert function but it still says it has to be spied. My Component has

method1(){
method2();
}
method2{
if(some condition){
alert('hello');
}
}

My unit test :

it('it should say hello', () => {
 spyOn(component, 'method1').and.callThrough();
   spyOn(window, 'alert');
component.method1();
expect(window.alert).toHaveBeenCalledWith('hello');

}

error is Expected spy alert to have been called with [ 'hello'] but it was never called

Because you have spied the method1() and your alert is being called from method2(). So Spying on method2() will pass the test. The following code should run:

 it('it should say hello', () => {
         spyOn(component, 'method2').and.callThrough();
         spyOn(window, 'alert');
         component.method1();
         expect(window.alert).toHaveBeenCalledWith('hello');

    }
