无法使用赛普拉斯中的 mocha-allure-reporter 读取未定义错误的属性“基础”

Question

我正在尝试在Cypress 中使用mocha-allure-reporter。我安装了mocha 和mocha-allure-reporter 作为开发依赖项，并在cypress.json 中提到mocha-allure-reporter 作为记者。

我尝试了example section of mocha allure page中引用的以下代码：

require('mocha-allure-reporter');

describe("simple test demo", () => {
  const testStep = allure.createStep("initial", () => {
    console.log("First Test")
  });

  it("simple passed test", () => {
    testStep();
  });
}

但是，我收到以下错误：

未捕获的类型错误：无法读取未定义的属性“基”

...在第一行本身：

require('mocha-allure-reporter')

在控制台上查看时，我发现错误源自 Allure 记者中的 var Base = require("mocha").reporters.Base 行：

var Base = require("mocha").reporters.Base;
var Allure = require("allure-js-commons");
...
...
global.allure = new Runtime(allureReporter);

/**
 * Initialize a new `Allure` test reporter.
 *
 * @param {Runner} runner
 * @param {Object} opts mocha options
 * @api public
 */
function AllureReporter(runner, opts) {
...
...

请注意，执行完成后，将在allure-results 目录中创建以下输出 xml 文件。

<?xml version='1.0'?>

请指导我。谢谢！

Answer 1

我只需安装它（连同 mocha）就可以使用 mocha-allure-reporter，

npm install mocha mocha-allure-reporter

并在 package.json 中设置脚本，遵循赛普拉斯的 npm 记者指南here

"scripts": {
  ...
  "cypress:run": "cypress run --reporter mocha-allure-reporter"

注意，我认为这些记者只使用赛普拉斯的“运行”命令，而不是赛普拉斯的“打开”命令。

输出是一个名为“allure-results”的文件夹，其中包含一堆 xml 文件。我认为这些可以使用 Allure 框架工具显示。

示例输出文件：

<?xml version='1.0'?>
<ns2:test-suite xmlns:ns2='urn:model.allure.qatools.yandex.ru' start='1547254197911' stop='1547254201289'>
    <name>Tasks Page</name>
    <title>Tasks Page</title>
    <test-cases>
        <test-case start='1547254199721' status='passed' stop='1547254199815'>
            <name>should have a title</name>
            <title>should have a title</title>
            <labels/>
            <parameters/>
            <steps/>
            <attachments/>
        </test-case>
    </test-cases>
</ns2:test-suite>

在 cy.task() 中运行诱惑代码

要运行诱惑代码，需要通过cy.task访问nodejs上下文。

例如，

/cypress/plugins/index.js

require('mocha-allure-reporter');

module.exports = (on) => {
  on('task', {
    allureTestStep () {
      const testStep = allure.createStep("initial", () => {
        console.log("First Test")
      });
      testStep()

      return null
    }
  })
}

规格

describe("simple test demo", () => {

  it("simple passed test", () => {
    cy.task('allureTestStep')
  });
})

请注意，这会在您启动赛普拉斯的命令窗口中生成控制台日志，而不是浏览器控制台。

但是，您可以将任务中的值传回测试中，具体取决于您实际尝试执行的操作（有关详细信息，请参阅文档）。
