Ant task to perform only JUnit tests doesn't run tests - java

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>

how to find the errors in junit classes while running jacoco in Ant build

I'm using Jacoco code coverage in my Ant build and build is success after using instrument for my junit classes as they have powermockito in it.
I'm getting errors in the junit classes when i ran through the ant and tests failed but build success.
I'm comipiling the src and test classes using WAS server jars from another build.xml and placed the class files in the dir.build folder. This folder is given as input for the instrument task to give me the instrumented classes. When the junit task is started it is saying that errors occured in the test classes and test failed. I used the printsummary ="on" and tried to generate logs using verbose.
I want to know what are the errors occuring while running the junit. Can somebody please tell me how can i see the errors in the Test classes.

One way that may help you. Hopefully someone can suggest an easier way - this is snippet from build.xml I used a few years ago before upgrade to JUNIT5.
<junit printsummary="on" showoutput="off" fork="true"
haltonerror="false" haltonfailure="false"
errorproperty="junit.errors" failureproperty="junit.failures" >
<formatter type="plain"/>
<formatter type="xml"/>
You'd need to check what outout files you get from JUNIT4 in your ${result.dir} and add ant action to grab and print out part of the junit output files to the console so that the final error lines were visible
<loadfile srcfile="${junit.stdout}" property="junit.summary">
<filterchain><tailfilter lines="30"/></filterchain>
</loadfile>
<echo>${junit.summary}</echo>
and then bail out of the build if there are errors:
<fail if="junit.failures">JUNIT failed - see ${result.dir}</fail>
<fail if="junit.errors" >JUNIT error - see ${result.dir}</fail>

Please help me find the reason for why this error occurs. The script is able to find the test case but at the end an error is thrown.
Add the required resources to the test classpath:
<pathelement path="${classpath}"/>
that in your case will be:
<classpath>
<pathelement path="bin" />
<pathelement location="hamcrest-core-1.3.jar" />
<pathelement location="junit.jar" />
</classpath>
As explained here
To make things a bit more flexible, we add one extra feature, which makes it possible to match multiple directory levels. This can be used to match a complete directory tree, or a file anywhere in the directory tree. To do this, "" must be used as the name of a directory. When ** is used as the name of a directory in the pattern, it matches zero or more directories. For example: /test/ matches all files/directories under /test/, such as /test/x.java, or /test/foo/bar/xyz.html, but not /xyz.xml.
'**' must be used to match folders, and not as wildcard to select partial file names.
Change your ant with:
<fileset dir="bin">
<include name="*.class" />
</fileset>
If you want to select all '*.class' files under every directory under bin/ then use:
<fileset dir="bin">
<include name="**/*.class" />
</fileset>
You will have now an error cause by the test report writer. You need to create a docs folder and everything will work.
The final build.xml will be:
<?xml version="1.0"?>
<project name="Ant-Test" default="main">
<target name="main">
<mkdir dir="docs"/>
<junit printsummary="yes" fork="yes" haltonfailure="no">
<classpath location="hamcrest-core-1.3.jar" />
<classpath location="junit-4.12.jar" />
<classpath path="bin/" />
<formatter type="plain" />
<batchtest fork="yes" todir="docs">
<fileset dir="bin">
<include name="**/*.class" />
</fileset>
</batchtest>
</junit>
</target>
</project>
Please try with following fileset tag:
<fileset dir="bin">
<include name="**.java" />
</fileset>
I'm not sure if junit task admits more than one classpath node, but anyway, it is a good practice to have just one. Moreover, your classpath is missing the classes directory. The right declaration would be like this:
<junit ...>
<classpath>
<pathelement path="bin"/>
<pathelement location="hamcrest-core-1.3.jar"/>
<pathelement location="junit.jar"/>
</classpath>
...
</junit>

How do I run a pitest ant script

I'm trying to create an ant script to run pitest to be able to automate my mutation testing. I am getting the error:

What is causing this error, and how can I fix it?
Edit: I changed pitClasspath="PhoneBook.path" to pitClasspath="pit.path" and now I have a new error:

I don't know if that is better or worse, but hopefully it will be helpful in finding the problem.
A working example of a pitest ant build is provided at
https://github.com/hcoles/pitest-ant-example
I suggest you start with this and edit it until you have a working build for your codebase.
One difference I can see is that you have not included junit on the pitest path.
Your build looks a little strange as it seems to be tied to eclipse. If you are running from the IDE why not use the eclipse plugin?
Also, if you are not tied to Ant, you might want to consider maven as an alternative.
I believe much of your problem is that you're trying to use the Eclipse generated build.xml file, which doesn't contain the mutation testing target, and the target which you've added to remedy this has some errors.
I would suggest starting with the project here and attempting to understand how it works, and then changing their build.xml file to fit your needs.
However if this doesn't work, judging from your other question, the following build.xml should work if:
You divide your files into two source directories "src" and "test"
Both src and test folders contain the package "pbook"
You change the name of your tests to end in "Test" rather than begin in it

JaCoCo JUnit Ant Error : Process Fork Failed

I have an Ant Build file. I added jacoco coverage task to get the coverage of my junit testcases. It says process fork failed.
<jacoco:coverage output="file" destfile="${result.exec.file}">
<!-- forkmode="perTest" printsummary="on" maxmemory="3072m" failureProperty="test.failure" haltonerror="false" includeAntRuntime="true"-->
<junit printsummary="on" fork="true">
<classpath refid="test.run.path" />
<syspropertyset>
<propertyref builtin="commandline" />
</syspropertyset>
<!-- usefile="true" -->
<formatter type="xml" usefile="true" />
<!-- failureproperty="test.failure" haltonerror="false" -->
<batchtest todir="reports/junit-xml" fork="yes">
<fileset dir="src/test/java">
<include name="**/AllTest.java" />
</fileset>
</batchtest>
</junit>
</jacoco:coverage>
<junitreport todir="${reports.dir}/junit-xml">
<fileset dir="${reports.dir}/junit-xml">
<include name="TEST-*.xml" />
</fileset>
<report format="frames" todir="${reports.dir}/junit-html" />
</junitreport>
Have you tried this without jacoco? I ask because I'm having the same problem with fork failure and I'm not using jacoco. I also have another project's ant script doing the same thing and it works fine. Yet somehow the project and ant script I'm currently working on fails the fork. In both cases I have to have fork set to "yes" because I'm specifying an alternate jvm for the junit block.
Maybe the classpath length issue is worth exploring. I know that in my case the ant script that's failing the fork has a longer class path than the one that's working. I had another project with a longer classpath that was also failing to fork but I didn't really need to fork so I just set it to "no".

TFS Can't Find Unit Test Results from Ant/JUnit build

I have a java project that has just been imported into TFS and I've been trying to get TFS to output the results of the unit tests.
At the end of the TFSBuild.proj file I have the following:
<ItemGroup>
<!-- Ant Call Configuration.
The build file called should be included in the workspace of the build definition.
-->
<AntBuildFile Include="$/PROJECT_NAME/Main/tfsbuild.xml">
<Targets>build,test</Targets>
<Properties>BinariesRoot=$(BinariesRoot);BuildDefinitionName=$(BuildDefinitionName);BuildDefinitionUri=$(BuildDefinitionUri);BuildDirectory=$(BuildDirectory);BuildNumber=$(BuildNumber);DropLocation=$(DropLocation);LogLocation=$(LogLocation);SourceGetVersion=$(SourceGetVersion);TestResultsRoot=$(TestResultsRoot);TeamProject=$(TeamProject);WorkspaceName=$(WorkspaceName);WorkspaceOwner=$(WorkspaceOwner)</Properties>
<Lib></Lib>
</AntBuildFile>
<!-- JUnit XML Results files should be created using the XML formatter
and be located in the following path
-->
<JUnitLogFiles Include="$(BinariesRoot)\**\TEST-*.xml" />
</ItemGroup>
This kicks off the build and tells TFS where to find the junit test results.
The issue is, TFS is not finding the unit test results even though I can see through the logs that the tests were run.
I almost gave up on this, and changed my ant file to produce a junit report and store it with the build artifacts. I changed my ant task to be:
<target name="test" depends="compile-tests">
<echo>Running unit tests, output should be in ${junit.output}</echo>
<junit printsummary="yes">
<classpath>
<pathelement path="${compile.classpath}" />
<pathelement path="${lib.dir}/junit-4.0.jar" />
<pathelement path="${build}" />
<pathelement path="${dist-classes}" />
</classpath>
<formatter type="xml" />
<batchtest fork="yes" todir="${junit.output}">
<fileset dir="${src.test}">
<include name="**/*Test.java" />
</fileset>
</batchtest>
</junit>
<mkdir dir="${DropLocation}/${BuildNumber}/test_results" />
<junitreport todir="${junit.output}">
<fileset dir="${junit.output}">
<include name="TEST-*.xml" />
</fileset>
<report todir="${DropLocation}/${BuildNumber}/test_results" />
</junitreport>
</target>
But after checking the output from the next build, I realised that the JUnit output was saved as TESTS-TestSuites.xml, not TEST-*.xml. I changed my TFSBuild.proj file accordingly, and now have the build results appearing in TFS.
Somehow the junitreport task still picks up the output though.
