得到TypeError：生成mochawesome报告时，无法使用赛普拉斯读取未定义的属性“ passs”

Question

我遇到了令人困惑的错误，实际上我不知道如何解决这样的库问题，我试图生成我的赛普拉斯测试用例，以将下面的报告变成我的package.json设置文件

{
"devDependencies": {
    "cypress": "^3.1.5",
    "mocha": "^6.0.2",
    "mocha-junit-reporter": "^1.18.0",
    "mocha-multi-reporters": "^1.1.7",
    "mochawesome": "^3.1.1",
    "mochawesome-merge": "^1.0.7",
    "mochawesome-report-generator": "^3.1.5"
}

我认为安装它们后没有问题，然后，我运行

柏树奔跑--reporter mochawesome

然后测试完成，在该BOOM之后，我遇到了这样的错误

这是我拥有的stacktrace，有人知道要解决此问题吗？

Answer 1

使用mocha版本6.0.0或更高版本时出现相同的错误。

如果可以，请尝试使用version 5.2.0，直到问题解决为止，并且它将正常工作。

Answer 2

Mocha 6 需要实例化一个统计收集器

\n\n

i\xe2\x80\x99ve 现已更新、测试并发布了更新的模块，这些模块使用 mocha 6 修复了此问题，但也保留了与 mocha 5 及更早版本的向后兼容性。

\n\n

https://www.npmjs.com/package/cypress-multi-reporters \n https://www.npmjs.com/package/mocha-junit-reporters

\n\n

针对 Mocha 5 的示例\n针对 Mocha 6 的示例

\n\n

所需的改变是最小的

\n\n

npm i mocha-junit-reporters

\n\n

npm i cypress-multi-reporters

\n\n

在reporterOpts.json中

\n\n

{\n  "reporterEnabled": "mocha-junit-reporters, mochawesome",\n  "mochaJunitReportersReporterOptions": {\n    "mochaFile": "cypress/reports/junit/test_results[hash].xml",\n    "toConsole": false\n  },\n  "mochawesomeReporterOptions": {\n    "reportDir": "cypress/reports/mocha",\n    "quiet": true,\n    "overwrite": false,\n    "html": false,\n    "json": true\n  }\n} \n

\n\n

在 cypress.json 中

\n\n

{\n  ...\n  "reporter": "cypress-multi-reporters",\n  "reporterOptions": {\n    "configFile": "reporterOpts.json"\n  }\n

\n\n
