问题描述

我正在尝试从Testng-result.xml包含套件结果的文件中读取属性,并且我想读取结果状态并将其传递给 kibana,以获取仅 XPath 查询的结果

xpath =>
   [
   "/testng-results/suite/test/class/test-method/text()", "test-method",
   "/testng-results/suite/test/class/test-method[3]/@status/text()", "test-status",
   "/testng-results/suite/test/class/test-method[@name='test']", "test-result"
   ]        

这是 XML 文件:

<testng-results skipped="0" failed="0" total="10" passed="10">
  <suite name="TestSuite" duration-ms="498075" started-at="2018-06-13T07:00:21Z" finished-at="2018-06-13T07:08:39Z">
    <groups>
    </groups>
    <test name="UIHTML5TC10SettingSupportUI" duration-ms="20867" started-at="2018-06-13T07:00:21Z" finished-at="2018-06-13T07:00:42Z">
      <class name="com.mtfilemedia.ifive.testscripts.UIHTML5TC10SettingSupportUI">
        <test-method status="PASS" signature="testSetup()[pri:0, instance:com.mtfilemedia.ifive.testscripts.UIHTML5TC10SettingSupportUI@7e0e6aa2]" name="testSetup" is-config="true" duration-ms="14" started-at="2018-06-13T12:30:21Z" finished-at="2018-06-13T12:30:21Z">
          <reporter-output>
          </reporter-output>
        </test-method> <!-- testSetup -->
        <test-method status="PASS" signature="beforeMethod()[pri:0, instance:com.mtfilemedia.ifive.testscripts.UIHTML5TC10SettingSupportUI@7e0e6aa2]" name="beforeMethod" is-config="true" duration-ms="24" started-at="2018-06-13T12:30:21Z" finished-at="2018-06-13T12:30:21Z">
          <reporter-output>
          </reporter-output>
        </test-method> <!-- beforeMethod -->
        <test-method status="PASS" signature="test()[pri:0, instance:com.mtfilemedia.ifive.testscripts.UIHTML5TC10SettingSupportUI@7e0e6aa2]" name="test" duration-ms="19520" started-at="2018-06-13T12:30:21Z" finished-at="2018-06-13T12:30:40Z">
        </test-method> <!-- test -->
        <test-method status="PASS" signature="afterMethod()[pri:0, instance:com.mtfilemedia.ifive.testscripts.UIHTML5TC10SettingSupportUI@7e0e6aa2]" name="afterMethod" is-config="true" duration-ms="172" started-at="2018-06-13T12:30:41Z" finished-at="2018-06-13T12:30:42Z">
          <reporter-output>
          </reporter-output>
        </test-method> <!-- afterMethod -->
        <test-method status="PASS" signature="testTearDown()[pri:0, instance:com.mtfilemedia.ifive.testscripts.UIHTML5TC10SettingSupportUI@7e0e6aa2]" name="testTearDown" is-config="true" duration-ms="2" started-at="2018-06-13T12:30:42Z" finished-at="2018-06-13T12:30:42Z">
          <reporter-output>
          </reporter-output>
        </test-method> <!-- testTearDown -->
      </class> <!-- com.mtfilemedia.ifive.testscripts.UIHTML5TC10SettingSupportUI -->
    </test>

对于此配置,我得到了test_status,但没有得到测试结果。

解决方案


如果您想获取某个测试方法的属性,例如name属性,则 XPath 表达式的开头必须找到所需的测试方法节点,假设您正在寻找名为“test”的节点 /testng-results/suite/test/class/test-method[@name='test'] :获取该元素的任何属性,将属性轴附加到表达式。因此,您可以获得这些 XPath 表达式来访问属性:

  • 地位: /testng-results/suite/test/class/test-method[@name='test']/@status
  • 签名: /testng-results/suite/test/class/test-method[@name='test']/@signature
  • 姓名: /testng-results/suite/test/class/test-method[@name='test']/@name
  • 是配置: /testng-results/suite/test/class/test-method[@name='test']/@is-config
  • 持续时间-毫秒: /testng-results/suite/test/class/test-method[@name='test']/@duration-ms
  • 开始于: /testng-results/suite/test/class/test-method[@name='test']/@started-at
  • 完成时间: /testng-results/suite/test/class/test-method[@name='test']/@finished-at

您的第一个 XPath 表达式提取所有测试方法的文本内容,只产生空白节点。您的第二个 XPath 表达式不正确 - 属性具有值,但没有 text() 子节点(实际上,根本没有子节点)。如果您需要将属性的值提取为字符串,请使用string()函数,例如string(/testng-results/suite/test/class/test-method[@name='test']/@status). 您的第三个 XPath 表达式获取整个 test-method 元素而不是它的属性。

希望这可以帮助。
