计算Ant执行的JUnit测试的总和

Question

我有一个Ant目标，它使用<batchset>运行JUnit测试。

运行时，显示以下内容：

Tests run: 3, Failures: 0, Errors: 0, Skipped: 0, Time elapsed: 0.497 sec

我想要的是所有类执行的测试的总数。有简单的方法吗？

<junit>任务可以将测试结果输出为XML文件。这些XML文件可以使用免费的第三方XmlTask库进行处理。

首先，在<junit>下，添加<formatter type="xml" usefile="true"/>:

<junit>
    <formatter type="xml" usefile="true"/>
    <batchtest ... />
</junit>

然后<xmltask>可以用于组合XML文件，并计算失败和错误的总和：

<taskdef name="xmltask" classname="com.oopsconsultancy.xmltask.ant.XmlTask" />
<!-- Create a buffer named "testsuiteNode" that holds the -->
<!-- <testsuite> nodes from the JUnit reports. -->
<xmltask>
    <fileset includes="*.xml"/>
    <copy path="/testsuite" append="true" buffer="testsuiteNode"/>
</xmltask>
<!-- Create an XML document containing a single element: <root/>. -->
<!-- Then insert the <testsuite> nodes under <root/> -->
<!-- Then calculate the sums of the various errors and failures. -->
<!-- Finally, store the sums in various properties. -->
<xmltask>
    <insert path="/"><![CDATA[<root/>]]></insert>
    <insert path="/root" buffer="testsuiteNode"/>
    <copy path="sum(/root/testsuite/@errors)" property="test-errors-count"/>
    <copy path="sum(/root/testsuite/@failures)" property="test-failures-count"/>
    <copy path="sum(/root/testsuite/@errors | /root/testsuite/@failures)"
        property="test-failures-and-errors-count"/>
    <copy path="sum(/root/testsuite/@tests)" property="test-total-count"/>
</xmltask>
<echo>test-errors-count: ${test-errors-count}</echo>
<echo>test-failures-count: ${test-failures-count}</echo>
<echo>test-failures-and-errors-count: ${test-failures-and-errors-count}</echo>
<echo>test-total-count: ${test-total-count}</echo>

样本输出

 [echo] test-errors-count: 1
 [echo] test-failures-count: 2
 [echo] test-failures-and-errors-count: 3
 [echo] test-total-count: 5
