im currently trying to test the methods that i have created and the methods in my if statement are not being called. and im completely at a loss. I am new too jest though so im sure its something simple im missing.
describe('isSingleScreen', () => { beforeEach(() => { jest.clearAllMocks(); jest.spyOn(utilMethods, 'isDualScreen').mockReturnValue(true); }); it('autoScreenAdd', () => { // Arrange const singleScreenAddSpy = jest.spyOn( singleScreenMethods,'singleScreenAdd' ); const dualScreenAddSpy = jest.spyOn(dualScreenMethods, 'dualScreenAdd'); // Act utilMethods.autoScreenAdd({}); // Assert expect(singleScreenAddSpy).toBeCalledTimes(0); expect(dualScreenAddSpy).toBeCalled(); expect(dualScreenAddSpy).toBeCalledTimes(1); }); });export const isDualScreen = (): boolean => { return Dimensions.get('window').width > 1000 ? true : false;};export const autoScreenAdd = (element: IDualComponent) => { if (isDualScreen()) { dualScreenAdd(element); } else { singleScreenAdd(element); }};this is the error i receive
expect(jest.fn()).toBeCalledTimes(expected) Expected number of calls: 0 Received number of calls: 1 30 | // Assert 31 | expect(autoScreenAddSpy).toBeCalled();> 32 | expect(singleScreenAddSpy).toBeCalledTimes(0); | ^ 33 | expect(dualScreenAddSpy).toBeCalled(); 34 | expect(dualScreenAddSpy).toBeCalledTimes(1); 35 | });
