Ant task to perform only JUnit tests doesn't run tests_问答_开发者

I'm trying to make an ant target that only runs the JUnit tests on a project without any other prior actions (no depends). I'm using Emma to instrument these in another target, and then I have another target that does a bytecode mutation on these instrumented classes. All that is working and I can get JUnit to run in that target after I've performed the instrumentation/mutation steps but I need to have the ability to just run the JUnit tests separately from this compile-instrument-mutate chain.

I've build a target that looks like this:

<target name="mutant-test-run" description="Run tests with mutation applied">
    <path id="run.classpath">
        <pathelement location="${out.dir}" />
    </path>
    <mkdir dir="${reports}" />
    <junit printsummary="yes" fork="true">
        <classpath>
    <pathelement location="${out.instr.dir}" />
        <path refid="junit.classpath" />
    <path refid="famaLib.classpath" />
    <path refid="run.classpath" />
    <path refid="emma.lib" />
    </classpath>
        <jvmarg value="-Demma.coverage.out.file=${coverage.dir}/coverage.emma" />
        <jvmarg value="-Demma.coverage.out.merge=true" />

        <formatter type="plain" />
        <formatter type="xml" />

        <batchtest todir="${reports}">
            <fileset dir="${src.dir}">
                <include name="test1.java" />
                <include name="test2.java" />
                <include name="test3.java" />
                <include name="test4.java" />
                <include name="test5.java" />
            </fileset>
        </batchtest>
    </junit>
    <emma enabled="${emma.enabled}">
        <report sourcepath="${src.dir}" sort="+block,+name,+method,+class" metrics="method:70,block:80,line:80,class:100">           
            <fileset dir="${coverage.dir}">
                <include name="*.emma" />
            </fileset>
            <!-- for every type of report desired, configure a nested
         element; various report parameters can be inherited from the parent <report>
         and individually overridden for each report type:-->
            <txt outfile="${coverage.dir}/coverage.txt" depth="package" columns="class,method,block,line,name" />
            <xml outfile="${coverage.dir}/coverage.xml" depth="package" />
            <html outfile="${coverage.dir}/coverage.html" depth="method" columns="name,class,method,block,line" />
        </report>
    </emma>
</target>

The jUnit task within the target doesn't get executed however, all I get is the output from the mkdir task and the emma task.

How do you setup an ant target to only do JUnit tests?

It looks like your fileset is wrong for the batchtest element, I think maybe you need to include a **:

<batchtest todir="${reports}">
    <fileset dir="${src.dir}">
        <include name="test1.java" />
        <include name="test2.java" />
        <include name="test3.java" />
        <include name="test4.java" />
        <include name="test5.java" />
    </fileset>
</batchtest>

From the examples on the page JUnit Task, you can use:

<batchtest fork="yes" todir="${reports.tests}">
    <fileset dir="${src.tests}">
        <include name="**/*Test*.java"/>
        <exclude name="**/AllTests.java"/>
    </fileset>
</batchtest>

Where the ** means in any sub-directory.

Another example:

<batchtest todir="${collector.dir}" unless="hasFailingTests">
    <fileset dir="${collector.dir}" includes="**/*.java" excludes="**/${collector.class}.*"/>
</batchtest>
