I have a code in React
$.get('/bin/data', (response) => {
this.data = response;
});
This is my test case:
$document = {
on: jest.fn().mockName('$document.on'),
};
expect(window.$).toBeUndefined();
$ = jest.fn().mockName('$').mockReturnValue($document);
$.get = () => {};
jest.spyOn($, 'get').mockName('$.get').mockImplementation(response => jest.fn()); // not sure what to do here such that callback function is also covered
window.$ = $;
Everything is working fine, but the callback function is not getting covered.
Got if solved.
jest.spyOn($, 'get').mockName('$.get').mockImplementation((url, myMockFn) => {
myMockFn({ name: 'Tom' });
});
