    copied!<p>The <a href="http://emma.sourceforge.net/userguide_single/userguide.html#N10291" rel="nofollow noreferrer">User Guide has a good example of how to set up your build script</a> so that you not only seperate the instrumented code from the execution, but it's also all contained in the same <code>&lt;target&gt;</code> so that you don't have to run a series of different targets, but instead you can just do something like <code>ant emma tests</code> (if <code>ant tests</code> was how you normally ran your unit tests, for example).</p> <p>Here's their example:</p> <pre><code>&lt;target name="emma" description="turns on EMMA instrumentation/reporting" &gt; &lt;property name="emma.enabled" value="true" /&gt; &lt;!-- EMMA instr class output directory: --&gt; &lt;property name="out.instr.dir" value="${basedir}/outinstr" /&gt; &lt;mkdir dir="${out.instr.dir}" /&gt; &lt;/target&gt; &lt;target name="run" depends="init, compile" description="runs the examples" &gt; &lt;emma enabled="${emma.enabled}" &gt; &lt;instr instrpathref="run.classpath" destdir="${out.instr.dir}" metadatafile="${coverage.dir}/metadata.emma" merge="true" /&gt; &lt;/emma&gt; &lt;!-- note from matt b: you could just as easily have a &lt;junit&gt; task here! --&gt; &lt;java classname="Main" fork="true" &gt; &lt;classpath&gt; &lt;pathelement location="${out.instr.dir}" /&gt; &lt;path refid="run.classpath" /&gt; &lt;path refid="emma.lib" /&gt; &lt;/classpath&gt; &lt;jvmarg value="-Demma.coverage.out.file=${coverage.dir}/coverage.emma" /&gt; &lt;jvmarg value="-Demma.coverage.out.merge=true" /&gt; &lt;/java&gt; &lt;emma enabled="${emma.enabled}" &gt; &lt;report sourcepath="${src.dir}" &gt; &lt;fileset dir="${coverage.dir}" &gt; &lt;include name="*.emma" /&gt; &lt;/fileset&gt; &lt;txt outfile="${coverage.dir}/coverage.txt" /&gt; &lt;html outfile="${coverage.dir}/coverage.html" /&gt; &lt;/report&gt; &lt;/emma&gt; &lt;/target&gt; </code></pre>
