node.js - Cypress 在浏览器外部执行 API 调用

Question

我使用 axios 创建了函数，该函数将在每次测试运行之前设置测试数据。它们位于 FOY.js 文件中

const axios = require('axios');

//Get the token needed for Bearer Authorization
async function getJWT() {
    const bearerToken = await axios.post('https://www.example.com', {username: 'user', password: 'test1234'});
    return bearerToken.data.access_token
}

//Get the UserId from the email address.
async function getUserId(emailAddress) {
    var bearerToken = await getJWT();
    const userId = await axios.get('https://example.com/users/search?contains='+emailAddress+'', {'headers':{Authorization: 'Bearer '+bearerToken+''}});
    console.log(userId.data.users[0].id);
    return userId.data.users[0].id
}

//Delete a record for a user
async function TMDeleteFOY (emailAddress) {
    var bearerToken = await getJWT();
    var userId = await getUserId(emailAddress);
    const response = await axios.delete('https://example2.com/'+userId+'/record', {'headers':{Authorization: 'Bearer '+bearerToken+''}});
    return response.status
}
module.exports.TMDeleteFOY = TMDeleteFOY;
module.exports.TMUpdateFOY = TMUpdateFOY;

使用 cy.task()

beforeEach(function() {
    cy.task('TMDeleteFOY', 'example@mail.com');
});

插件/index.js

const FOY = require('../resetScripts/talentMine/FOY');

module.exports = (on, config) => {
    on('task', {
        'TMDeleteFOY': (emailaddress) => {
         return FOY.TMUpdateFOY(emailaddress);
        }
    })
};

您需要从任务代码中返回一些内容，以便 Cypress 知道要等待什么，并在运行其他代码之前知道您的任务已完成。

查看 cy.task() documentation :

In the task plugin event, the command will fail if undefined is returned. This helps catch typos or cases where the task event is not handled.

要解决此问题，您只需修改任务代码即可返回 promise 。目前，您没有返回任何内容。

在您的plugins/index.js中:

const FOY = require('../resetScripts/talentMine/FOY');

module.exports = (on, config) => {
    on('task', {
        'TMDeleteFOY': (emailaddress) => {
            // CHANGED: return a promise so Cypress can wait for it
            return FOY.TMDeleteFOY(emailaddress);
        }
    })
}

在您的 FOY.js 文件中(为简洁起见，排除了不相关的部分):

// start of your FOY.js...

//Delete a record for a user
async function TMDeleteFOY (emailAddress) {
    var bearerToken = await getJWT();
    var userId = await getUserId(emailAddress);
    // CHANGED: return this promise chain so Cypress can wait for it
    return await axios.delete('https://example2.com/'+userId+'/record', {'headers':{Authorization: 'Bearer '+bearerToken+''}});
}

// end of your FOY.js...
