Webdriverio 5 用于单元测试和功能测试

Question

我有一个使用node和webpack编写的项目。

我正在为应用程序编写测试，由于我的应用程序的输出是可视化的，我使用了webdriverio 5，它运行得很好(功能测试(。但是，当我添加单元测试时，它只是失败，尽管在测试报告中它显示它是假的，日志表明它失败了。

这是我的package.json文件的样子

{
"name": "webdriverio-test",
"version": "1.0.0",
"description": "",
"main": "app/index.js",
"scripts": {
"install-selenium": "./node_modules/.bin/selenium-standalone install",
"start-selenium": "./node_modules/.bin/selenium-standalone start",
"test": "./node_modules/.bin/wdio wdio.conf.js",
"allure-report": "allure generate allure-results --clean && allure open"
},
"keywords": [],
"author": "",
"license": "ISC",
"devDependencies": {
"@wdio/allure-reporter": "^5.12.1",
"@wdio/cli": "^5.12.5",
"@wdio/local-runner": "^5.12.5",
"@wdio/mocha-framework": "^5.12.1",
"@wdio/selenium-standalone-service": "^5.12.1",
"@wdio/sync": "^5.12.3"
}
}

这是我的测试文件的外观

const assert = require('assert'); 
const index = require('../../app/index').default 
describe('test browser', function () { 
it('should have the right title', function ()  { 
browser.url('https://webdriver.io'); 
const title = browser.getTitle(); 
//assert.strictEqual(title, 'WebdriverIO · Next-gen WebDriver test framework for Node.js'); 
console.log("**********I am here*************"); 
assert.equal(5,5); 
}); 
}); 

describe('test code', function () { 
it('should have do the right thing', function ()  { 
const c = index.add(3,4); 
assert.equal(c, 7); 
}); 
}); 

当我使用 webdriverio 命令运行此代码时，我得到以下堆栈跟踪

我的问题是我可以使用 wdio 运行单元测试和功能测试，还是使用 mocha 和 wdio 来运行这些测试是个好主意？

当我运行浏览器测试时，所有浏览器测试都运行良好

Answer 1

我相信在一个文件中运行不同类型的测试不是一个好主意(因为只有第一个描述可以工作 - 对于您的示例(，并且日志将根据 wdio 设置编写。我在不同的文件中运行了您的示例，它工作正常 - 2 通过 最好将 UI 测试移动到具有 Wdio 的 package.json 设置的同一文件夹，并使用 mocha 将单元测试移动到另一个单独的文件夹。
