Question

我们有一个 Jenkins 安装和一些由 NUnit 测试的项目。这工作正常，它写了一个 NUnit 结果 XML 文件。然后我们有一个 'Publish NUnit test result report' post-构建步骤。但是自星期五以来它产生了这个错误：

Recording NUnit tests results
ERROR: Step ‘Publish NUnit test result report’ aborted due to exception: 
java.io.IOException: remote file operation failed: C:\Jenkins\workspace\xxx at hudson.remoting.Channel@205d5d5c:CIAgent: java.io.IOException: Failed to read C:\Jenkins\workspace\xxx\temporary-junit-reports\TEST-xxx_Tests.TestsWithRealServers.TestWithTwoLocals_1_2.xml

XML 文件存在于工作目录中。我提到该文件的第一行如下所示：

<?xml version="1.0" encoding="UTF-8"?><testsuite errors="0" failures="0" name="xxx_Tests.TestsWithRealServers.TestWithTwoLocals" skipped="6" tests="6" time="">

所以我猜它失败了，因为时间属性是空的。

有人知道我该如何解决这个问题或者为什么会出现这个错误吗？谢谢！

Answer 1

您最近是否将 jenkins JUnit 插件升级到 1.12？本次更新有一个reported issue。您可以尝试降级回 1.11。

Answer 2

顺便说一下，Jenkins 插件不支持 Nunit 3 XML 格式。我在 Jenkins 上也有类似的问题。我曾经将 Nunit 3 结果格式转换为 Nunit 2 格式。

"C:\NUnit 3.5.0\nunit3-console.exe" /result:\MyApplication.xml;format=nunit2 "D:\Jenkins\workspace\MyApplication.Tests.dll"
