我有 Hudson 作为持续集成服务器,我想使用“发布 JUnit 测试结果报告”选项。但是我不使用 xUnit 工具进行测试,而是使用 shell 脚本运行测试并以简单格式返回结果。我正在考虑制作一个将这些结果转换为 JUnit 格式的脚本。所以我对 JUnit 文件的外观很感兴趣?
8 回答
几个月前我做过类似的事情,结果证明这种简单的格式足以让 Hudson 接受它作为测试协议:
<testsuite tests="3">
<testcase classname="foo1" name="ASuccessfulTest"/>
<testcase classname="foo2" name="AnotherSuccessfulTest"/>
<testcase classname="foo3" name="AFailingTest">
<failure type="NotEnoughFoo"> details about failure </failure>
</testcase>
</testsuite>
这个问题有更详细的答案:Spec。用于 JUnit XML 输出
我刚刚抓取了其他人已链接到的junit-4.xsd,并使用名为XMLSpear的工具将架构转换为空白 XML 文件,其选项如下所示。这是(稍微清理一下)结果:
<?xml version="1.0" encoding="UTF-8"?>
<testsuites disabled="" errors="" failures="" name="" tests="" time="">
<testsuite disabled="" errors="" failures="" hostname="" id=""
name="" package="" skipped="" tests="" time="" timestamp="">
<properties>
<property name="" value=""/>
</properties>
<testcase assertions="" classname="" name="" status="" time="">
<skipped/>
<error message="" type=""/>
<failure message="" type=""/>
<system-out/>
<system-err/>
</testcase>
<system-out/>
<system-err/>
</testsuite>
</testsuites>
其中一些项目可能会多次出现:
- 只能有一个
testsuites
元素,因为这就是 XML 的工作方式,但testsuite
元素中可以有多个元素testsuites
。 - 每个
properties
元素可以有多个子元素property
。 - 每个
testsuite
元素可以有多个子元素testcase
。 - 每个
testcase
元素可以有多个error
、failure
、system-out
或system-err
子元素。
Anders Lindahl问题的最佳答案是指xsd 文件。
就我个人而言,我发现这个 xsd 文件也非常有用(我不记得我是如何找到那个的)。它看起来不那么令人生畏,而且就我使用它而言,所有元素和属性似乎都被 Jenkins 识别(v1.451)
但有一件事:当添加多个<failure ...
元素时,Jenkins 中只保留了一个。创建 xml 文件时,我现在将所有失败合并为一个。
2016 年 11 月更新该链接现在已断开。一个更好的选择是来自cubic.org 的这个页面:JUnit XML 报告文件格式,其中已经做出了很好的努力来提供一个合理的文档示例。下面复制了示例和 xsd,但它们的页面看起来更好。

我找不到任何关于此的好的信息,所以我做了一些试验和错误。Jenkins (v1.585) 可以识别以下属性和字段(并且只有这些)。
<?xml version="1.0" encoding="UTF-8"?>
<testsuite>
<!-- if your classname does not include a dot, the package defaults to "(root)" -->
<testcase name="my testcase" classname="my package.my classname" time="29">
<!-- If the test didn't pass, specify ONE of the following 3 cases -->
<!-- option 1 --> <skipped />
<!-- option 2 --> <failure message="my failure message">my stack trace</failure>
<!-- option 3 --> <error message="my error message">my crash report</error>
<system-out>my STDOUT dump</system-out>
<system-err>my STDERR dump</system-err>
</testcase>
</testsuite>
(我从这个示例 XML 文档开始,然后从那里向后工作。)
我决定发布一个新的答案,因为一些现有的答案已经过时或不完整。
首先:没有什么像JUnit XML Format Specification
,因为 JUnit 不生成任何类型的 XML 或 HTML 报告。
XML 报告生成本身来自 Ant JUnit 任务/Maven Surefire 插件/Gradle(无论您使用哪个来运行测试)。XML 报告格式首先由 Ant 引入,后来被 Maven(和 Gradle)改编。
如果有人只需要官方的 XML 格式,那么:
- 有一个 maven surefire 生成的 XML 报告的模式,可以在这里找到:surefire-test-report.xsd。
- 对于 ant 生成的 XML,这里有一个 3rd 方模式可用(但它可能有点过时)。
希望它会帮助某人。
基本结构 这是一个 JUnit 输出文件的示例,显示了一个跳过和失败的结果,以及一个通过的结果。
<?xml version="1.0" encoding="UTF-8"?>
<testsuites>
<testsuite name="JUnitXmlReporter" errors="0" tests="0" failures="0" time="0" timestamp="2013-05-24T10:23:58" />
<testsuite name="JUnitXmlReporter.constructor" errors="0" skipped="1" tests="3" failures="1" time="0.006" timestamp="2013-05-24T10:23:58">
<properties>
<property name="java.vendor" value="Sun Microsystems Inc." />
<property name="compiler.debug" value="on" />
<property name="project.jdk.classpath" value="jdk.classpath.1.6" />
</properties>
<testcase classname="JUnitXmlReporter.constructor" name="should default path to an empty string" time="0.006">
<failure message="test failure">Assertion failed</failure>
</testcase>
<testcase classname="JUnitXmlReporter.constructor" name="should default consolidate to true" time="0">
<skipped />
</testcase>
<testcase classname="JUnitXmlReporter.constructor" name="should default useDotNotation to true" time="0" />
</testsuite>
</testsuites>
以下是典型 JUnit XML 报告的文档结构。请注意,报告可以包含 1 个或多个测试套件。每个测试套件都有一组属性(记录环境信息)。每个测试套件还包含 1 个或多个测试用例,如果测试未通过,每个测试用例将包含跳过、失败或错误节点。如果测试用例通过了,那么它将不包含任何节点。有关哪些属性对每个节点有效的更多详细信息,请参阅以下“模式”部分。
<testsuites> => the aggregated result of all junit testfiles
<testsuite> => the output from a single TestSuite
<properties> => the defined properties at test execution
<property> => name/value pair for a single property
...
</properties>
<error></error> => optional information, in place of a test case - normally if the tests in the suite could not be found etc.
<testcase> => the results from executing a test method
<system-out> => data written to System.out during the test run
<system-err> => data written to System.err during the test run
<skipped/> => test was skipped
<failure> => test failed
<error> => test encountered an error
</testcase>
...
</testsuite>
...
</testsuites>
“JUnit”和“xUnit”结果有多种模式。
- Apache Ant 的 JUnit 输出的 XSD 可以在以下位置找到:https ://github.com/windyroad/JUnit-Schema (归功于这个答案:https ://stackoverflow.com/a/4926073/1733117 )
- 来自 Jenkins xunit-plugin 的 XSD 可以在以下位置找到:https ://github.com/jenkinsci/xunit-plugin/tree/master/src/main/resources/org/jenkinsci/plugins/xunit/types (下
model/xsd
)
请注意,Jenkins xunit-plugin 使用了多个版本的模式(当前最新版本junit-10.xsd
增加了对 Erlang/OTP Junit 格式的支持)。
一些测试框架以及“xUnit”风格的报告插件也使用他们自己的秘诀来生成“xUnit”风格的报告,那些可能不使用特定的模式(请阅读:他们尝试但这些工具可能无法针对任何一个模式)。Jenkins 中的 Python 单元测试?给出了其中几个库的快速比较以及生成的 xml 报告之间的细微差别。
关于使用 python 的好答案:(有很多方法可以做到) Jenkins 中的 Python 单元测试?
恕我直言,最好的方法是编写 python unittest 测试并安装 pytest(类似于'yum install pytest')来安装 py.test。然后像这样运行测试: 'py.test --junitxml results.xml test.py'。您可以运行任何 unittest python 脚本并获取 jUnit xml 结果。
https://docs.python.org/2.7/library/unittest.html
在 jenkins 构建配置 构建后操作 使用 result.xml 和您生成的任何更多测试结果文件添加“发布 JUnit 测试结果报告”操作。
