Author: jhm Date: Wed Oct 24 03:05:46 2007 New Revision: 587844 URL: http://svn.apache.org/viewvc?rev=587844&view=rev Log: FailureRecorder * remove duplicate "no-op" statement (javadoc + code) * use BuildListener for writing at the end of <junit> instead of overwriting the file all the time * minor comment edit * pass project reference to <junit> nested elements (eg listener) * order methods by interfaces * some log messages in the recorder * can use Ant properties for setting the location
FormatterElement * don't set the project reference if there is already one build.xml * use ant property instead of system property for configuring FailureRecorder Modified: ant/core/trunk/build.xml ant/core/trunk/docs/manual/OptionalTasks/junit.html ant/core/trunk/src/etc/testcases/taskdefs/optional/junit.xml ant/core/trunk/src/main/org/apache/tools/ant/taskdefs/optional/junit/FailureRecorder.java ant/core/trunk/src/main/org/apache/tools/ant/taskdefs/optional/junit/FormatterElement.java ant/core/trunk/src/tests/junit/org/apache/tools/ant/taskdefs/optional/junit/JUnitTaskTest.java Modified: ant/core/trunk/build.xml URL: http://svn.apache.org/viewvc/ant/core/trunk/build.xml?rev=587844&r1=587843&r2=587844&view=diff ============================================================================== --- ant/core/trunk/build.xml (original) +++ ant/core/trunk/build.xml Wed Oct 24 03:05:46 2007 @@ -1605,6 +1605,8 @@ <!-- run the tests --> <mkdir dir="${build.junit.xml}" /> <property name="test.junit.vmargs" value=""/> + <property name="ant.junit.failureCollector" + value="${junit.collector.dir}/${junit.collector.class}"/> <junit printsummary="${junit.summary}" haltonfailure="${test.haltonfailure}" fork="${junit.fork}" @@ -1622,8 +1624,6 @@ <sysproperty key="build.compiler" value="${build.compiler}"/> <sysproperty key="tests.and.ant.share.classloader" value="${tests.and.ant.share.classloader}"/> - <sysproperty key="ant.junit.failureCollector" - value="${junit.collector.dir}/${junit.collector.class}"/> <classpath> <path refid="tests-classpath"/> <pathelement location="${junit.collector.dir}"/> Modified: ant/core/trunk/docs/manual/OptionalTasks/junit.html URL: http://svn.apache.org/viewvc/ant/core/trunk/docs/manual/OptionalTasks/junit.html?rev=587844&r1=587843&r2=587844&view=diff ============================================================================== --- ant/core/trunk/docs/manual/OptionalTasks/junit.html (original) +++ ant/core/trunk/docs/manual/OptionalTasks/junit.html Wed Oct 24 03:05:46 2007 @@ -357,7 +357,7 @@ <p>The fourth formatter named <code>failure</code> (since Ant 1.8.0) collects all failing <code>testXXX()</code> methods and creates a new <code>TestCase</code> which delegates only these -failing methods.
