我在一个小项目中一直使用Jest，并且在使用Jest模拟时遇到了麻烦。我有一个实用程序文件，导出命名自定义错误构造函数。我需要在我的测试文件中模拟这些函数。我不想使用Jest文档中显示的手动模拟技术（即将模拟文件放在__mocks__中），而是想在测试文件中定义模拟。我在我的测试文件中尝试这样的事情：
const errorMock = () => {
return {
configNotFoundError: jest.fn(() => new Error()),
invalidJSONError: () => jest.fn(() => new Error()),
}
};
jest.mock('./error', errorMock);
const { configNotFoundError, invalidJSONError } = require('./error');
但是我收到以下错误：
babel-plugin-jest-hoist: The second argument of `jest.mock`
must be an inline function.
有人可以帮我理解我做错了吗？
答案 0 :(得分：1)
我最近在命名导出方面遇到了类似的问题。
