Question

我正在使用Robotium在Android模拟器上运行UI测试并尝试使用emma进行覆盖。 xml覆盖率报告已成功创建。但我发现覆盖率报告中有一些类不是真实代码的一部分。如。。

<class name="CalculatorData$Message">
        <coverage type="class, %" value="0%   (0/1)"/>
        <coverage type="method, %" value="0%   (0/5)"/>
        <coverage type="block, %" value="0%   (0/43)"/>
        <coverage type="line, %" value="0%   (0/3)"/>

        <method name="&lt;static initializer&gt;">
          <coverage type="method, %" value="0%   (0/1)"/>
          <coverage type="block, %" value="0%   (0/24)"/>
          <coverage type="line, %" value="0%   (0/3)"/>
        </method>
        <method name="CalculatorData$Message (String, int): void">
          <coverage type="method, %" value="0%   (0/1)"/>
          <coverage type="block, %" value="0%   (0/5)"/>
          <coverage type="line, %" value="0%   (0/1)"/>
        </method>
        <method name="CalculatorData$Message (String, int, CalculatorData$1): void">
          <coverage type="method, %" value="0%   (0/1)"/>
          <coverage type="block, %" value="0%   (0/5)"/>
          <coverage type="line, %" value="0%   (0/1)"/>
        </method>
        <method name="valueOf (String): CalculatorData$Message">
          <coverage type="method, %" value="0%   (0/1)"/>
          <coverage type="block, %" value="0%   (0/5)"/>
          <coverage type="line, %" value="0%   (0/1)"/>
        </method>
        <method name="values (): CalculatorData$Message []">
          <coverage type="method, %" value="0%   (0/1)"/>
          <coverage type="block, %" value="0%   (0/4)"/>
          <coverage type="line, %" value="0%   (0/1)"/>
        </method>
      </class>

我们在CalculatorData中根本没有名为Message的内部类。它看起来与内部类覆盖数据相同，因此我无法使用emma过滤器过滤它们。有谁知道如何在覆盖率报告中删除这些数据？

这是我的相关蚂蚁脚本。

<property name="emma.filter" value="-com.example.coverage.R, -com.example.coverage.R$*, -com.example.coverage.BuildConfig" />   
<property name="emma.default.filter" value="com.example.coverage.R, com.example.coverage.R$*, com.example.coverage.BuildConfig" />  
<import file="${sdk.dir}/tools/ant/build.xml" />

<property name="test.runner.with.report" value="com.zutubi.android.junitreport.JUnitReportTestRunner" />

看起来你的Message课程中可能有一个名为CalculatorData的枚举。这会占到它吗？

非源代码类包含在emma xml覆盖率报告中
