javascript - 在 mocha 中将变量从 before() 传递到 it()

Question

自动化的新手，我正在尝试将 token 值从 block() 之前传递到 it() 并且我变得不确定。

能够生成成功并保存在token

const { spec } = require('pactum');
const request = require('request');
const userConfig = require('../config/credential.json')

process.env.NODE_TLS_REJECT_UNAUTHORIZED = '0';

let token = "";
let authToken = "";

describe('POST /jobs', function () {
    before(function () {
        var option = {
            'method': 'POST',
            'url': 'https://login.microsoftonline.com/<tenant_id>/oauth2/v2.0/token',
            'headers': {
                'Content-Type': 'application/x-www-form-urlencoded'
            },
            form: {
                'client_id': `${userConfig.client_id}`,
                'grant_type': 'password',
                'Password': `${userConfig.Password}`,
                'UserName': `${userConfig.UserName}`,
                'scope': `${userConfig.scope}`,
                'client_secret': `${userConfig.client_secret}`
            }
        };
        request(option, function (error, response) {
            if (error) throw new Error(error)
            const modifyResponse = JSON.parse(response.body)
            token = modifyResponse["access_token"]
        })
    })
    it('Create Job should return 201 status code', async () => {
        authToken = this.token
        console.log('------------>', authToken)
        await spec()
            .post('https://localhost:3000/jobs')
            .withHeaders('Authorization', `Bearer ${authToken}`)
            .withHeaders('X-Client-Id', 'AzureDataLoaderUI')
            .withHeaders('X-Message-Created-Ts', '2022-JUN-07 04:06')
            .withHeaders('X-Message-Id', '4e8fb14c-c71f-46f8-b41a-561d393037ce')
            .withHeaders('X-Transaction-Created-Ts', '2022-JUN-07 04:06')
            .withHeaders('X-Transaction-Id', 'f11c97dc-a6eb-4ff7-aff6-de47c4686941')
            .withHeaders('X-User-Id', 'AutoTestUser')
            .withHeaders('Ocp-Apim-Subscription-Key', 'a731ccf0510849c690d23bb42ecef9d3')
            .withHeaders('aeg-sas-key', 'b6LrYspQUAY2XnxkrDFDFDYsb8U2zqMQAzaQoZcQ=')
            .withJson({ "product": "IRT", "entity": "CENTRE PROVISIONING AND RECIPIENT DETAILS", "operation": "UPDATE", "jobName": "AUTOPERF02", "studyId": "AUTO02" })
            .expectStatus(201);
    });
});

我认为您还需要等待 request() 调用，或者改用 Cypress cy.request()。

let token = "";
let authToken = "";

describe('POST /jobs', function () {
    before(async function () {
        var option = {
            'method': 'POST',
            'url': 'https://login.microsoftonline.com/<tenant_id>/oauth2/v2.0/token',
            'headers': {
                'Content-Type': 'application/x-www-form-urlencoded'
            },
            form: {
                'client_id': `${userConfig.client_id}`,
                'grant_type': 'password',
                'Password': `${userConfig.Password}`,
                'UserName': `${userConfig.UserName}`,
                'scope': `${userConfig.scope}`,
                'client_secret': `${userConfig.client_secret}`
            }
        };
        await request(option, function (error, response) {
            if (error) throw new Error(error)
            const modifyResponse = JSON.parse(response.body)
            token = modifyResponse["access_token"]
        })
    })
    it('Create Job should return 201 status code', async () => {
        authToken = token
       ...

使用cy.request，您无需等待

cy.request(option)
  .then(response => {
    // if error, it's already thrown
    token = response.body["access_token"]
  })

使用 Mocha done() 表示请求已完成

以上 async 仅适用于基于 Promise 的请求。

等待 request(options, callback) 完成传入 Mocha 的 done() 函数并在设置 token 后调用它。

这是一个简单的例子，使用 JSONPlaceholder 来请求一些数据

const request = require('request');

let token;

before(function (done) {
  request({
    'method': 'GET', 
     'url': 'https://jsonplaceholder.typicode.com/todos/1' 
  }, function (error, response) {
    const modifyResponse = JSON.parse(response.body)
    token = modifyResponse.title
    done()                          // signal end of request
  })
})

it('sees the token', () => {
  expect(token).to.eq('delectus aut autem')   // passes
})
