Question

I know that to run junit from command line you can do this:

java org.junit.runner.JUnitCore TestClass1 […other test classes…]

However, I want to run many tests together and manually typing “TestClass1 TestClass2 TestClass3…” is just inefficient.

Current I organize all test classes in a directory (which has sub-directories indicating the packages). Is there any way that I can run junit from command line and let it execute these test classes all at once?

Thanks.

I found that I can write an Ant buildfile to achieve this. Here is the sample build.xml:

<target name="test" description="Execute unit tests">
    <junit printsummary="true" failureproperty="junit.failure">
        <classpath refid="test.classpath"/>
        <!-- If test.entry is defined, run a single test, otherwise run all valid tests -->
        <test name="${test.entry}" todir="${test.reports}" if="test.entry"/>
        <batchtest todir="tmp/rawtestoutput" unless="test.entry">
            <fileset dir="${test.home}">
                <include name="**/*Test.java"/>
                <exclude name="**/*AbstractTest.java"/>
            </fileset>
            <formatter type="xml"/>
        </batchtest>
    <fail if="junit.failure" message="There were test failures."/>
</target>

With this build file, if you want to execute a single test, run:

ant -Dtest.entry=YourTestName

If you want to execute multiple tests in batch, specify the corresponding tests under the <batchtest>...</batchtest>
as shown in the above example.
