英文:
Facing issue when import file and use inside jest.mock
问题
我正在尝试从另一个文件中导出对象，并在jest.mock内部使用它。
jest.mock('@theme/theme-provider', async () => {const dummyThemeStyle = await import('app/style/__tests__/themeObjct.json');return {useTheme: () => ({themeStyle: {...dummyThemeStyle,},}),};});
但它始终返回useTheme不是一个函数。如何解决这个问题？

jest.mock('@theme/theme-provider', async() => {const dummyThemeStyle = await import('app/style/__tests__/themeObjct.json');return {useTheme: () => ({themeStyle: {...dummyThemeStyle,},}),};});
but it always return useTheme is not a function How to solve this issue

移除 async/await 并在 factory 函数内部使用 require 加载模块。工厂函数如何被调用？请参阅 v29.5.0/packages/jest-runtime/src/index.ts#L1000
if (this._mockFactories.has(moduleID)) {// 以上的检查使这个操作合法const module = this._mockFactories.get(moduleID)!();mockRegistry.set(moduleID, module);return module as T;}
如您所见，工厂函数不应是异步函数
jest.mock('@theme/theme-provider', () => {const dummyThemeStyle = require('app/style/__tests__/themeObjct.json');return {useTheme: () => ({themeStyle: {...dummyThemeStyle,},}),};});
英文:
Remove async/await for the factory function and use require to load the module inside the factory function. How the factory function be called? see v29.5.0/packages/jest-runtime/src/index.ts#L1000
if (this._mockFactories.has(moduleID)) {// has check above makes this okconst module = this._mockFactories.get(moduleID)!();mockRegistry.set(moduleID, module);return module as T;}
As you can see, the factory function should not be an asynchronous function
jest.mock('@theme/theme-provider', () => {const dummyThemeStyle = require('app/style/__tests__/themeObjct.json');return {useTheme: () => ({themeStyle: {...dummyThemeStyle,},}),};});
