我目前在使用Jenkins的CI流程中工作，触发针对nodejs服务器后端的mocha测试。
对于一些reasong xunit测试记者没有与詹金斯合作。 test-resul.xml是空的，工作仍然失败。我们能够通过运行来实现它：
npm install mocha-jenkins-reporter
在测试触发之前，如下所示：
JUNIT_REPORT_PATH=test_report.xml JUNIT_REPORT_STACK=1 NODE_ENV=test node ./node_modules/.bin/mocha --globals * --reporter mocha-jenkins-reporter --no-colors
现在我得到了部分结果，因为某些原因并非所有测试都在运行。他们停在测试套件的中间，没有任何通知或错误消息。我还注意到生成的xml缺少关闭标记的根元素。我通过运行来解决这个问题：
echo '</testsuites>' >> test-result.xml
除此之外，我还注意到在测试执行期间内存消耗激增。 这是npm安装输出，这一步是这项工作的第一步：
+ npm -v
3.8.6
+ npm install

答案 0 :(得分：1)
内存峰值似乎很可能是一支冒烟的枪 - 你超过资源配额并被杀，或者只是崩溃。这似乎可以通过创建的部分文件得到证实 - 文件最终会在片段中间结束，这是一个强烈的崩溃或强制杀戮指示。
我自己使用ActionHero，它使用的内存非常少。 Sequelize是其大部分用法，即便如此，我在生产API节点上使用超过180MB的RAM也是罕见的。您没有具体说明“内存峰值”有多大，但我会先调查一下您的流程使用的程度以及分配方式。有很多工具可用于此，但我建议使用类似StrongLoop，PM2，NewRelic或Ruxit的东西，只是因为它可以帮助您快速找到它。所有这些工具都有免费或试用选项。
除此之外，您还可以通过单独运行测试来进行一些调查。当您致电mocha时，您可以传入一个测试套件来执行
最后，如果您使用Bash作为shell，请尝试删除--globals *作为测试。 Bash可能会在执行Mocha之前扩展它，将其替换为当前工作目录中的文件列表。如果结果是抛出任何东西，你可以把它放在引号中或创建一个mocha.opts文件。这是我的，作为一个例子：
--recursive
--reporter spec
--timeout 15000
--ignore-leaks
--slow 3000
--globals api,assert
--require test/bootstrap
test
请注意，命令行参数可以覆盖opts-file设置。这就是我在这里--reporter spec的原因 - 这减少了我在我的本地开发环境中手动运行mocha的输入（我可以只运行mocha而没有参数）。您仍然可以将报告者设置为CI堆栈中所需的报告者。
