Running jUnit with ANT - How to execute all tests without using #Suite? - ant

I'd like to execute all tests in a /test directory without using annotations such as
#Suite.SuiteClasses( ....)
In the past i had a single class, which was calling many other classes to test them all. This approach is no longer acceptable.
I have a /test directory, underneath which i have a number of packages, each containing several tests.
In my current ANT script, i have:
<target name="compileTest" depends="compile" description="compile jUnit">
<javac srcdir="${test}" destdir="${bin}" includeantruntime="true" />
</target>
followed by
<target name="test" depends="compileTest">
<junit printsummary="yes" fork="no" haltonfailure="no">
<classpath location="${bin}" />
<formatter type="plain" />
</junit>
</target>
In the past, i had
<test name="MyCollectionOfTests" />
I'd rather not do this anymore.
What am i missing? Please advise.

You can use a nested batchtest. For instance:
<junit printsummary="on"
fork="on"
dir="${test.build}"
haltonfailure="false"
failureproperty="tests.failed"
showoutput="true">
<classpath>
<path refid="tests.classpath"/>
</classpath>
<batchtest todir="${test.report}">
<fileset dir="${test.gen}">
<include name="**/Test*.java"/>
</fileset>
<fileset dir="${test.src}">
<include name="**/Test*.java"/>
<exclude name="gen/**/*"/>
</fileset>
</batchtest>
</junit>
In its simplest form, you can simply add a nested:
<batchtest todir="report">
<fileset dir="test"/>
</batchtest>
to your junit call.

Jacoco coverage with Ant throws java.lang.instrument.IllegalClassFormatException: Error while instrumenting class

I integrated Jacoco with my Ant build. When I run the build, the test case is executed successfully followed by the below exception in my TEST-com.worker.ManagerTest.xml.
When I add excludes="*" the error is not thrown. But the jacoco.exec is generated with 1kb size and when I run the report nothing is generated. Can someone let me know what am I missing?
Exception:
<![CDATA[java.lang.instrument.IllegalClassFormatException: Error while instrumenting class com/dataaccess/GenericDao.
at org.jacoco.agent.rt_6qyg3i.CoverageTransformer.transform(CoverageTransformer.java:69)
Below is the jacoco build script.
<target name="test" depends="test-compile">
<mkdir dir="${report.dir}" />
<jacoco:coverage destfile="${report.dir}/jacoco.exec" xmlns:jacoco="antlib:org.jacoco.ant" exclclassloader="sun.reflect.DelegatingClassLoader:javassist.Loader">
<junit fork="true" forkmode="once" printsummary="on">

</target>
<target name="report" depends="test">

<property name="report.dir.file" value="${report.dir}/jacoco.exec"/>
<jacoco:report>

<fileset dir="${src.dir}">
<include name="**/*.java"/>
</fileset>
</sourcefiles>
</structure>
<html destdir="${report.dir}/coverage"/>
</jacoco:report>
</target>
This is the empty report I get.

I used the latest version 0.8.7 and it worked.

Can't run Groovy test cases from Ant

My Ant target looks like this:
<target name="junit" depends="compile">
<junit haltonfailure="true" printsummary="true">
<classpath>
<fileset dir="${idea.dir}/lib" includes="junit.jar" />
<fileset dir="${build.dir}" includes="**" />
</classpath>
<formatter type="plain" usefile="true" />
<batchtest fork="false" todir="${out.dir}">
<fileset dir="${build.dir}" includes="test_*/*Test.class" />
</batchtest>
</junit>
</target>
All compiled classes from the project are in ${build.dir}, as well as all compiled test cases. The latter are within ${build.dir}/test_* sub folders.
There is one test class ${build.dir}/test_ecs/EntityManagerTest.class, which apparently is found in batchtest. However, Ant gives me this output in the junit report:
test_ecs.EntityManagerTest
java.lang.ClassNotFoundException: test_ecs.EntityManagerTest
at java.lang.ClassLoader.loadClass(ClassLoader.java:358)
at java.lang.Class.forName0(Native Method)
at java.lang.Class.forName(Class.java:270)
at com.intellij.rt.ant.execution.AntMain2.main(AntMain2.java:30)
Now, what I don't understand is: Why is the test case class file found, but then the error says exactly that class is not found?
try modifying the <classpath>.. section like this:
<junit ..>
<classpath>
<pathelement location="${idea.dir}/lib/junit.jar"/>
<pathelement path="${build.dir}"/>
</classpath>
and see if it runs...
I suspect your issue is the classpath declaration:
<classpath>
<fileset dir="${idea.dir}/lib" includes="junit.jar" />
<fileset dir="${build.dir}" includes="**" />
</classpath>
Are your *.class files located in the build directory? Or a subdirectory of the build dir?
By way of example here's my standard junit task:
<junit printsummary="yes" haltonfailure="yes">
<classpath>
<path refid="test.path"/>
<pathelement path="${build.dir}/classes"/>
<pathelement path="${build.dir}/test-classes"/>
</classpath>
<formatter type="xml"/>
<batchtest fork="yes" todir="${build.dir}/test-reports">
<fileset dir="${test.src.dir}">
<include name="**/*Test*.java"/>
<exclude name="**/AllTests.java"/>
</fileset>
</batchtest>
</junit>
Note the classpath declaration. It includes the path to 3rd party dependency jars, the directory where I compiled my classes to and the directory I compiled my test classes to.

How to run dbunit task in ant?

It doesn't work in ant,
I'd like to run some classes that extend DatabaseTestCase
<path id="libs.dir">
<fileset dir="lib" includes="**/*.jar" />
</path>
<taskdef name="dbunit"
classname="org.dbunit.ant.DbUnitTask"/>
<!-- run all tests in the source tree -->
<junit printsummary="yes" haltonfailure="yes">
<formatter type="xml"/>
<batchtest fork="yes" todir="${reports.tests}">
<fileset dir="${src.tests}">
<include name="**/*Test*.java"/>
</fileset>
</batchtest>
</junit>
It says the following:
Buildfile: D:\kariakin\jdbc_task\build.xml
BUILD FAILED
D:\kariakin\jdbc_task\build.xml:15: taskdef class org.dbunit.ant.DbUnitTask cannot be found
using the classloader AntClassLoader[]
I think the problem is your taskdef, it's missing the path containing the dbunit jar:
<taskdef name="dbunit" classname="org.dbunit.ant.DbUnitTask" classpathref="libs.dir"/>

Running jUnit tests via ANT, clarification needed

Suppose you have a test directory that contains packages each of which contains jUnit tests.
In this setup, using ANT, how would you "run all tests?"
Assuming my jUnit has
<target name="test" depends="compileTest">
<junit fork="yes" printsummary="yes" haltonfailure="no">
<classpath location="${bin}" />
<formatter type="plain" />
<test name="_com.??.project.alltests.MyTests" />
</junit>
</target>
Where, MyTests has
#RunWith(Suite.class)
#Suite.SuiteClasses( { _ThisTest.class, _ThatTest.class })
public class OCTTests {
}
and _ThisTest itself contains some tests ..
Is it possible for the purposes of ANT script to avoid this ans simply say "Run all Tests you find in this directory"
Have a look at the nested batchtest element of the junit task.
You will find the following example on the junit task documentation page:
<junit printsummary="yes" haltonfailure="yes">
<classpath>
<pathelement location="${build.tests}"/>
<pathelement path="${java.class.path}"/>
</classpath>
<formatter type="plain"/>
<test name="my.test.TestCase" haltonfailure="no" outfile="result">
<formatter type="xml"/>
</test>
<batchtest fork="yes" todir="${reports.tests}">
<fileset dir="${src.tests}">
<include name="**/*Test*.java"/>
<exclude name="**/AllTests.java"/>
</fileset>
</batchtest>
</junit>

ant excluding files

I have to write an ant target for Junit report. It is an existing application. Some of the Test class files are named as TestSample.java or SampleTest.java. But there are some few java files which are not to do anything with junit testcases are written HeaderTest.java which doesnt extending TestCase.
How can i filter these calss files?
<junit printsummary="on" fork="off" haltonfailure="false" showoutput="true">
<classpath>
<path refid="CLASSPATH_JUNIT"/>
</classpath>
<batchtest fork="off" todir="${BUILD_TEST_DIR}">
<fileset dir="${TEST_CLASSES_DIR}">
<include name="**/*Test.class" />
<include name="**/Test*.class" />
</fileset>
</batchtest>
<formatter type="xml" />
</junit>
fileset has an exclude as well.
<exclude name="**/DoNotIncludeThisOne.class" />
Exclude them explicitely with <exclude name="**/HeaderTest.class"/>, or even better, refactor them so that they respect the naming convention : *Test classes should be test cases.
See http://ant.apache.org/manual/Types/fileset.html
