Question

在没有更改测试或测试环境的情况下，成功运行到2019年2月18日的cypress.io测试现在失败并出现错误。

Cypress.io是版本3.1.5

测试由jenkinsfile运行：

sh "npx cypress run --browser chrome  --reporter mocha-multi-reporters   --reporter-options configFile=config-v1-smoke.json  --spec \"cypress/integration/smoke/*.js\""

错误是：

Answer 1

mocha@6.0.0已于2019-02-18发行。通过将mocha从降级到最新版本mocha@5.2.0，可以缓解此问题。使用mocha@5.2.0，可以按照--spec中的指定运行正确的cypress.io测试集。

mocha@6.0.0中的某些内容正在通过mocha报告为cypress.io创建测试规范问题。

华盛顿关于全球问题的评论不正确。 Mocha 6需要实例化统计收集器。

我现在已经更新，测试并发布了更新的模块，这些模块可以用mocha 6修复此问题，但仍保持与mocha 5和更早版本的向后兼容性。

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

Example against Mocha 5 Example against Mocha 6

所需的更改很小

npm i mocha-junit-reporters

npm i cypress-multi-reporters

在ReporterOpts.json中

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

在cypress.json中

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

希望PR可以很快合并到源仓库中，但现在享受吧

截至2019年2月18日，是否还有其他人使cypress.io测试开始失败？
