Question

我最近将Cobertura集成到了我的Ant构建脚本中，我想知道我是否正确使用它，因为它大大减慢了运行单元测试所需的时间。

以下是控制台输出示例：

...
[junit] Running gov.nyc.doitt.gis.webmap.strategy.markup.ViewportDeterminingMarkupStrategyTest
[junit] Tests run: 5, Failures: 0, Errors: 0, Time elapsed: 0.38 sec
[junit] Flushing results...
[junit] Flushing results done
[junit] Cobertura: Loaded information on 282 classes.
[junit] Cobertura: Saved information on 282 classes.
[junit] Running gov.nyc.doitt.gis.webmap.strategy.markup.VisibleFeatureTypesMarkupInfoTest
[junit] Tests run: 1, Failures: 0, Errors: 0, Time elapsed: 0.434 sec

[junit] Tests run: 3, Failures: 0, Errors: 0, Time elapsed: 2.016 sec
[junit] Flushing results...
[junit] Flushing results done

[junit] Running gov.nyc.doitt.gis.webmap.strategy.markup.basemap.BasemapByZoomLevelAndCenterPointStrategyTest
[junit] Tests run: 4, Failures: 0, Errors: 0, Time elapsed: 1.853 sec
[junit] Flushing results...
[junit] Flushing results done
[junit] Cobertura: Loaded information on 282 classes.
[junit] Cobertura: Saved information on 282 classes.
...

在每次测试之后，Cobertura说：

[junit] Cobertura: Loaded information on 282 classes.
[junit] Cobertura: Saved information on 282 classes.
...

这是我的Ant构建脚本中的单元测试任务：

    <target name="unit-test" depends="compile-unit-test">
    <delete dir="${reports.xml.dir}" />
    <delete dir="${reports.html.dir}" />
    <mkdir dir="${reports.xml.dir}" />
    <mkdir dir="${reports.html.dir}" />

    <junit fork="yes" dir="${basedir}" failureProperty="test.failed" printsummary="on">
        <!--
                Note the classpath order: instrumented classes are before the
                original (uninstrumented) classes.  This is important.
            -->
        <classpath location="${instrumented.dir}" />
        <classpath refid="test-classpath" />

        <formatter type="xml" />
        <test name="${testcase}" todir="${reports.xml.dir}" if="testcase" />
        <batchtest todir="${reports.xml.dir}" unless="testcase">
            <fileset dir="TestSource">
                <include name="**/*Test.java" />
                <exclude name="**/XmlTest.java" />
                <exclude name="**/ElectedOfficialTest.java" />
                <exclude name="**/ThematicManagerFixturesTest.java" />
            </fileset>
        </batchtest>
    </junit>
</target>

我的设置和输出是否正确？当单独运行并且在Cobertura的构建脚本中运行3分钟时，单元测试是否正常需要2.234秒？

来自cobertura-anttask reference：

出于同样的原因，如果您正在使用ant 1.6.2或更高版本可能想设置forkmode =“一次”这将只导致一个JVM 为所有JUnit测试启动，并将减少开销 Cobertura每次读取/写入覆盖数据文件的JVM 启动/停止。

（重点是我的。）

Cobertura的单元测试速度很慢
