| <title>JUnit Task</title> |
| </head> |
| <body> |
| |
| <h2><a name="junit">JUnit</a></h2> |
| <h3>Description</h3> |
| |
| <p>This task runs tests from the JUnit testing framework. The latest |
| version of the framework can be found at |
| <a href="http://www.junit.org">http://www.junit.org</a>. |
| This task has been tested with JUnit 3.0 up to JUnit 3.8.1; it won't |
| work with versions prior to JUnit 3.0.</p> |
| <p><strong>Note:</strong> This task depends on external libraries not included |
| in the Ant distribution. See <a href="../install.html#librarydependencies"> |
| Library Dependencies</a> for more information. |
| </p> |
| <p> |
| <strong>Note</strong>: |
| You must have <code>junit.jar</code> and the class files for the |
| <code><junit></code> task in the same classpath. |
| You can do one of: |
| <ol> |
| <li> |
| Put both <code>junit.jar</code> and the optional tasks jar file in |
| <code>ANT_HOME/lib</code>. |
| </li> |
| <li> |
| Do not put either in <code>ANT_HOME/lib</code>, and instead |
| include their locations in your <code>CLASSPATH</code> environment variable. |
| </li> |
| <li> |
| Do neither of the above, and instead, specify their locations using |
| a <code><classpath></code> element in the build file. |
| |
| See <a href="../../faq.html#delegating-classloader" target="_top">the |
| FAQ</a> for details. |
| </ol> |
| </p> |
| |
| |
| <p>Tests are defined by nested <code>test</code> or |
| <code>batchtest</code> tags (see <a href="#nested">nested |
| elements</a>).</p> |

| |
| <p>By using the <code>errorproperty</code> and <code>failureproperty</code> |
| attributes, it is possible to |
| perform setup work (such as starting an external server), execute the test, |
| clean up, and still fail the build in the event of a failure.</p> |
| |
| <p>The <code>filtertrace</code> attribute condenses error and failure |
| stack traces before reporting them. |
| It works with both the plain and XML formatters. It filters out any lines |
| that begin with the following string patterns:<pre> |
| "junit.framework.TestCase" |
| "junit.framework.TestResult" |
| "junit.framework.TestSuite" |
| "junit.framework.Assert." |
| "junit.swingui.TestRunner" |
| "junit.awtui.TestRunner" |
| "junit.textui.TestRunner" |
| "java.lang.reflect.Method.invoke(" |
| "org.apache.tools.ant."</pre></p> |
| |
| <h3><a name="nested">Nested Elements</a></h3> |
| |
| <p>The <code><junit></code> task |
| supports a nested <code><classpath></code> |
| element that represents a <a href="../using.html#path">PATH like |
| structure</a>.</p> |
| |
| <h4>jvmarg</h4> |
| |
| <p>If <code>fork</code> is enabled, additional parameters may be passed to |
| the new VM via nested <code><jvmarg></code> elements. For example:</p> |
| |
| <pre> |
| <junit fork="yes"> |
| <jvmarg value="-Djava.compiler=NONE"/> |
| ... |
| </junit> |
| </pre> |
| |
| <p>would run the test in a VM without JIT.</p> |
| |
| <p><code><jvmarg></code> allows all attributes described in <a |
| href="../using.html#arg">Command-line Arguments</a>.</p> |
| |
| <h4>sysproperty</h4> |
| |
| <p>Use nested <code><sysproperty></code> elements to specify system |
| properties required by the class. These properties will be made available |
| to the VM during the execution of the test (either ANT's VM or the forked VM, |
| if <code>fork</code> is enabled). |
| The attributes for this element are the same as for <a href="../CoreTasks/exec.html#env">environment variables</a>.</p> |
| |
| <pre> |
| <junit fork="no"> |
| <sysproperty key="basedir" value="${basedir}"/> |
| ... |
| </junit> |
| </pre> |
| |
| <p>would run the test in ANT's VM and make the <code>basedir</code> property |
| available to the test.</p> |
| |
| |
| <h4>env</h4> |
| |
| <p>It is possible to specify environment variables to pass to the |
| forked VM via nested <code><env></code> elements. For a description |
| of the <code><env></code> element's attributes, see the |
| description in the <a href="../CoreTasks/exec.html#env">exec</a> task.</p> |
| |
| <p>Settings will be ignored if <code>fork</code> is disabled.</p> |
| |
| <h4>formatter</h4> |
| |
| <p>The results of the tests can be printed in different |
| formats. Output will always be sent to a file, unless you set the |
| <code>usefile</code> attribute to <code>false</code>. |
| The name of the file is determined by the |
| name of the test and can be set by the <code>outfile</code> attribute |
| of <code><test></code>.</p> |
| |
| <p>There are three predefined formatters - one prints the test results |
| in XML format, the other emits plain text. The formatter named |
| <code>brief</code> will only print detailed information for testcases |
| that failed, while <code>plain</code> gives a little statistics line |
| for all test cases. Custom formatters that need to implement |
| <code>org.apache.tools.ant.taskdefs.optional.junit.JUnitResultFormatter</code> |
| can be specified.</p> |
| |
| <p>If you use the XML formatter, it may not include the same output |
| that your tests have written as some characters are illegal in XML |
| documents and will be dropped.</p> |

| <h3>Examples</h3> |
| |
| <pre> |
| <junit> |
| <test name="my.test.TestCase"/> |
| </junit> |
| </pre> |
| |
| <p>Runs the test defined in <code>my.test.TestCase</code> in the same |
| VM. No output will be generated unless the test fails.</p> |
| |
| <pre> |
| <junit printsummary="yes" fork="yes" haltonfailure="yes"> |
| <formatter type="plain"/> |
| <test name="my.test.TestCase"/> |
| </junit> |
| </pre> |
| |
| <p>Runs the test defined in <code>my.test.TestCase</code> in a |
| separate VM. At the end of the test, a one-line summary will be |
| printed. A detailed report of the test can be found in |
| <code>TEST-my.test.TestCase.txt</code>. The build process will be |
| stopped if the test fails.</p> |
| |
| <pre> |
| <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> |
| </pre> |
| |
| <p>Runs <code>my.test.TestCase</code> in the same VM, ignoring the |
| given CLASSPATH; only a warning is printed if this test fails. In |
| addition to the plain text test results, for this test a XML result |
| will be output to <code>result.xml</code>. |
| Then, for each matching file in the directory defined for |
| <code>${src.tests}</code> a |
| test is run in a separate VM. If a test fails, the build process is |
| aborted. Results are collected in files named |
| <code>TEST-</code><em>name</em><code>.txt</code> and written to |
| <code>${reports.tests}</code>.</p> |
