Question

我正在测试一个返回整数的实用函数，我正在尝试模拟调用它，但是即使经过数小时的搜索，我仍然找不到正确的方法。

我也尝试过`$wp_customize->add_section( 'the_event_secction_name' , array( 'title' => __( 'My Section Name', 'starter' ), 'priority' => 30 ) ); $wp_customize->add_setting( 'starter_new_setting_name' , array( 'default' => '#000000', 'transport' => 'refresh', ) ); $wp_customize->add_control( new WP_Customize_Color_Control( $wp_customize, 'link_color', array( 'label' => __( 'Header Color', 'starter' ), 'section' => 'the_event_secction_name', 'settings' => 'starter_new_setting_name', ) ) );`，但似乎没有用。

Authentication.js

spyOn()

Authentication.test.js

export function auth(username) {
  AsyncStorage.getItem('@app:id').then((id) => {
    if (id === username) {
      return 1;
    }
    return 0;
  });
}

我希望模拟调用import 'react-native'; import React from 'react'; import renderer from 'react-test-renderer'; // Note: test renderer must be required after react-native. import mockAxios from 'axios'; import mockAsyncStorage from '@react-native-community/async-storage'; import auth from '../App/Utils/Authorization'; test('should check whether the user whose username is entered as a paramter is the same as the user logged in the application', () => { auth = jest.fn(); expect(auth).toHaveReturned(); expect(mockAsyncStorage.getItem).toHaveBeenCalledTimes(1); expect(mockAsyncStorage.multiRemove).toHaveBeenCalledWith('@app:id'); });并获得成功的测试，相反，每运行auth()时都会得到一个错误"auth" is read-only作为输出。

您正在重新分配导入的成员emailsent，而不是以应有的方式使用SELECT dealercode, coupon_name, emailsent, responders, responserate, rn = rank() OVER (PARTITION BY dealercode, coupon_name ORDER BY responserate DESC, emailsent DESC) FROM table123;。调用jest模拟函数将返回未定义状态，相反，您可以使用mockFn.mockImplementation(fn)将函数绑定到模拟并测试其是否正在被调用或返回某个期望值。

auth

您可以验证函数检查mockFn.mock.results的输出，该检查存储通过调用函数进行的每次调用的结果。

jest.fn()

如何模拟使用玩笑调用效用函数？
