Error while running unit test case with Jest-Enzyme












0














I am trying to write a unit test case for a login page. I am unable to add other test cases as I am getting the error on the first line itself. Below is my login.spec.tsx code



import LoginPage from '../pages/login';
import { shallow } from 'enzyme';

describe('Login button', () => {
it('should login successfully', () => {
const button = shallow(<LoginPage />); // Error on this line
});
})


Below is the error which I am getting. But if I comment out the 'shallow' code, the test case is passed.
