это моя первая неделя, связанная с тестированием, и я запутался, я пытаюсь протестировать компонент SignIn, я протестировал снимок, чтобы убедиться, что поведение макета не меняется, затем я хочу протестировать поведение отправки, вот мой код:
signIn-component.jsx
import React, { useState } from 'react';
import FormInput from '../form-input/form-input.component';
import CustomButton from '../custom-button/custom-button.component';
import { connect } from 'react-redux';
import {
googleSignInStart,
emailSignInStart,
} from '../../redux/user/user.actions';
import './sign-in.styles.scss';
export const SignIn = ({ emailSignInStart, googleSignInStart }) => {
const [userCredentials, setCredentials] = React.useState({
email: '',
password: '',
});
const { email, password } = userCredentials;
const handleSubmit = async (event) => {
event.preventDefault();
emailSignInStart(email, password);
};
const handleChange = (event) => {
const { value, name } = event.target;
setCredentials({ ...userCredentials, [name]: value });
};
return (
<div className="sign-in">
<h2>I already have an account</h2>
<span>Sign in with your email and password</span>
<form onSubmit={handleSubmit}>
<FormInput
name="email"
type="email"
handleChange={handleChange}
value={email}
label="email"
required
/>
<FormInput
name="password"
type="password"
value={password}
handleChange={handleChange}
label="password"
required
/>
<div className="buttons">
<CustomButton type="submit"> Sign in </CustomButton>
<CustomButton
type="button"
onClick={googleSignInStart}
isGoogleSignIn
>
Sign in with Google
</CustomButton>
</div>
</form>
</div>
);
};
const mapDispatchToProps = (dispatch) => ({
googleSignInStart: () => dispatch(googleSignInStart()),
emailSignInStart: (email, password) =>
dispatch(emailSignInStart({ email, password })),
});
export default connect(null, mapDispatchToProps)(SignIn);
sign.test. js
import { shallow , mount } from 'enzyme';
import React from 'react';
import toJson from 'enzyme-to-json';
import { SignIn } from '../sign-in.component';
describe('Sign In component', () => {
let wrapper;
const mockemailSignInStart = jest.fn();
const mockgoogleSignInStart = jest.fn();
const mockHandleSubmit = jest.fn();
beforeEach(() => {
wrapper = shallow(<SignIn
emailSignInStart={mockemailSignInStart}
googleSignInStart={mockgoogleSignInStart}/>
);
});
it('expect to render signIn component', () => {
expect(toJson(wrapper)).toMatchSnapshot();
});
it('expect call fn on submit', () => {
wrapper.find('form').simulate('submit');
expect(mockHandleSubmit).toBeCalled();
});
});
Я пробовал монтировать и рендерить, но всегда ожидаю toBeCalled
всегда возвращаю 0
