【问题描述】：

我在 mocha chai 中创建了两个测试文件。我想访问文件 2 中要访问的文件 1 中的变量，以便我可以在文件 2 中使用它们

FILE1.js

const chai = require('chai');
const expect = chai.expect;
const addContext = require('mochawesome/addContext');
const _ = require('lodash');
const customerData = require('./data/customer.json');

let me,accessToken;

const invalidAccessToken = 'e0eXAiOiJKV1QiLCJhbGciOiJIUzI1NiIsImp0aSI6Imh0dHBzOmFjYmZsY2kybmVmcWtheXl6ZHM0In0.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.g0cdX7P34VemXT8nO5uaqKrKmSjc8caXWwS6T3Mo7Cb';


before(async() => {
    //API call 
    expect(response).to.have.property('data');
    expect(response.data).to.have.property('access-token');
    accessToken = (response.data['access-token']) ? response.data['access-token'] : '';  
});

我想在 FILE2.js 中访问这个 accessToken

【解决方案1】：

我建议将所有辅助变量保存在一个单独的文件中：

// variables.js
module.exports = {
  invalidAccessToken: 'e0eXAiOiJKV1QiLCJhbGciOiJIUzI1NiIsImp0aSI6Imh0dHBzOmFjYmZsY2kybmVmcWtheXl6ZHM0In0.eyJpYXQiOjE1NjI3NjMxNDQsIm5iZiI6MTU2Mjc2MzE0NCwiZXhwIjoxNTYzMjI1MTQ0LCJpc3MiOiJodHRwczpcL1wvam95YmlyZC5jb20iLCJhdWQiOiJodHRwczpcL1wvYXBpLXN0Zy5zdGl0Y2hpbmR1c3RyaWVzLmNvbSIsImp0aSI6Imh0dHBzOmFjYmZsY2kybmVmcWtheXl6ZHM0IiwiY3VzdG9tZXJfZmlyc3RfbmFtZSI6IlRvbSIsImN1c3RvbWVyX2xhc3RfbmFtZSI6IkNydWlzZSIsImN1c3RvbWVyX2NvbXBhbnkiOm51bGwsImN1c3RvbWVyX3Bhc3N3b3JkIjoiJDJ5JDEwJHJaWm1JNDlDRVJUa0VxQkNzTG1nemVFYVhVTHh0SVVOTlwvekI5T3phcXVEMnF4UWlJbDZrLiIsImN1c3RvbWVyX2lkIjozMDM2OTAsImN1c3RvbWVyX2VtYWlsIjoidGVzdDMucGFuZGl0QGdtYWlsLmNvbSJ9.g0cdX7P34VemXT8nO5uaqKrKmSjc8caXWwS6T3Mo7Cb'
};

然后你可以在任何文件中访问它：

const variables = require('./variables');

console.log(variables.invalidAccessToken);

// ...
