node.js - Bash 错误的退出代码

Question

在 CircleCI 上，我在配置文件中运行 npm run test-ci。

我的 package.json 中有以下脚本:

"test-ci": ". ./envvars/test.sh && nyc --all mocha --recursive --timeout 10000 && npm run report-coverage-ci",
"report-coverage-ci": "nyc report --reporter=text-lcov > coverage.lcov && codecov -f coverage.json && echo CodeCov Done",

问题是，Mocha 测试失败，但在 CircleCI 上仍然显示测试成功。

因此，如果 Mocha 测试失败，它不应该继续到报告代码覆盖率等所有内容的部分。但它正在继续该部分。

您可以看到下面日志的最后一部分(我已经撤回了一些敏感信息)。

我该如何解决这个问题？

Answer 1

就 bash 而言，您的命令行是正确的。问题似乎是命令 nyc --all mocha --recursive --timeout 10000 失败，但以零退出代码完成执行。因此 && 运算符认为可以转到下一个命令。

根本原因似乎是在 mocha 中，或者更具体地说是在 Node 中。 github上发布了一个问题: Mocha exits with 0 exit code with failing tests #2713

从问题评论来看，它似乎已在 Node 8.10 中修复。
