我最近将 Cobertura 集成到了我的 Ant 构建脚本中,我想知道我是否做得正确,因为它显着减慢了运行单元测试所需的时间。

这是一个示例控制台输出:

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

每次测试运行后,Cobertura 都会说:

[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?单独运行时单元测试需要 2.234 秒,而在使用 Cobertura 的构建脚本中运行时需要 3 分钟,这是否正常?

来自cobertura-anttask 参考

出于同样的原因,如果您使用的是 ant 1.6.2 或更高版本,那么您可能需要设置 forkmode="once"这将导致您的所有 JUnit 测试只启动一个 JVM,并减少 Cobertura 读取的开销/每次JVM启动/停止时写入覆盖数据文件。

(重点是我的。)
