在 mocha 中将变量从 before() 传递给 it()

Question

自动化非常新，我试图将令牌值从block()之前传递给it()并且我得到未定义。

能够成功生成并保存在token中

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);
    });
});

Answer 1

我认为您还需要等待request()调用，或者使用 Cypress cy.request()代替。

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 ，您不必等待

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()函数并在设置令牌后调用它。

这是一个简单的例子，使用 JSONPlaceholder 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
})

您可以使用 cypress 环境变量Cypress.env来保存令牌，然后在整个测试过程中的任何地方使用它。

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"]
      Cypress.env('token', modifyResponse['access_token']) //Set the token in env variable
    })
  })
  it('Create Job should return 201 status code', async () => {
    authToken = Cypress.env('token') //Get the token from env variable
    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)
  })
})

Answer 3

您也可以在it()块中使用function() ，并使用别名进行设置。

let authToken = "";

describe('POST /jobs', function () {
    before(function () {
      option = {...}
      cy.request(option)
        .then(response => {
          token = response.body["access_token"]
        })
        .as('token')   // alias will set "this.token"
    })

    it('Create Job should return 201 status code', async funtion() {
        authToken = this.token                           // "this" can be used here
        console.log('------------>', authToken)

Answer 4

猜猜专家已经回答了你的问题，因为你使用了 pactnum，这可以通过它来完成。

现在来解决这个问题，因为你在it块中有一个回调，这就是它不起作用的原因。 但正如Fody所说，专家们是正确的。

现在使用 pactnum，请按照以下步骤操作。

1. 创建一个文件（名称可以是任何东西，例如测试文件夹中的_base.spec.js ）。

    const userConfig = require('../config/credential.json') before(async function () { await spec() .post('https://login.microsoftonline.com/oauth2/v2.0/token') .withForm({ 'client_id': `${userConfig.client_id}`, 'grant_type': 'password', 'Password': `${userConfig.Password}`, 'UserName': `${userConfig.UserName}`, 'scope': `${userConfig.scope}`, 'client_secret': `${userConfig.client_secret}` }) .expectStatus(200) .stores('AUTH_TOKEN',"access_token") })

2. 现在只需在您的代码中调用它

            .post('https://<target_url>')
            .withHeaders('Authorization', `Bearer $S{AUTH_TOKEN}`)

Answer 5

在这种情况下，因为你有单独的块，只需使用

authToken = token  // no need for "this"
