Surefire report includes other testcases in TEST-XXX.xml files

I am a comitter on WebWork/XWork and we have changed to maven.

I have some strange behaviour using maven and running the unit tests using surefire.

I have discovered that surefire reports more testcases in it's TEST-XXX.xml files than there actually are testXXX methods for within the JUnit testcase.

As an example is this JUnit test file that has 13 methods for testing.

<testsuite errors="0" skipped="0" tests="13" time="0.015" failures="0" name="com.opensymphony.xwork2.interceptor.TimerInterceptorTest">

But in the bottom of the TEST-com.opensymphony.xwork2.interceptor.TimerInterceptorTest.xml file there are much more testcases listed (the 13 from the bottom is the correct tests):

<testcase time="0.109" name="testModelDrivenGetsPushedOntoStack"/>
<testcase time="0" name="testStackNotModifedForNormalAction"/>
<testcase time="0.015" name="testInterception1"/>
<testcase time="0" name="testInterception3"/>
<testcase time="0" name="testInterception2"/>
<testcase time="0" name="testBasicBlocked"/>
<testcase time="0" name="testBasicAllowed"/>
<testcase time="0" name="testAllSubpropertiesAllowed"/>
<testcase time="0" name="testEnsureOnlyPropsBlocked"/>
<testcase time="0" name="testAllSubpropertiesBlocked"/>
<testcase time="0" name="testBasicBlockAll"/>
<testcase time="0" name="testTreeBlocking"/>
<testcase time="0" name="testIncludesAndExcludesMethodWithExcludeWildcard"/>
<testcase time="0" name="testExcludesMethodWithWildCard"/>
<testcase time="0" name="testInvokesActionInvocationIfNoErrors"/>
<testcase time="0" name="testIncludesAndExcludesMethodWithIncludeWildcardAndNoMatches"/>
<testcase time="0" name="testIncludesAndExcludesMethodAllWildCarded"/>
<testcase time="0" name="testIncludesAndExcludesMethodWithIncludeWildcard"/>
<testcase time="0" name="testIncludesMethod"/>
<testcase time="0" name="testIncludesAndExcludesMethod"/>
<testcase time="0.015" name="testNoValidateAction"/>
<testcase time="0" name="testIncludesMethodWithWildcard"/>
<testcase time="0" name="testExcludesMethod"/>
<testcase time="0" name="testReturnsInputWithoutExecutingIfHasErrors"/>
<testcase time="0" name="testErrorLevel"/>
<testcase time="0" name="testInfoLevel"/>
<testcase time="0" name="testInputMethod"/>
<testcase time="0" name="testLogCategoryLevel"/>
<testcase time="0" name="testDebugLevel"/>
<testcase time="0" name="testWarnLevel"/>
<testcase time="0" name="testFatalLevel"/>
<testcase time="0" name="testLogCategory"/>
<testcase time="0" name="testTraceLevel"/>
<testcase time="0" name="testDefault"/>
<testcase time="0" name="testNoNamespace"/>
<testcase time="0" name="testTimerInterceptor"/>
<testcase time="0" name="testInvalidLogLevel"/>

So when you generate the surefire report using: mvn surefire-report:report
The HTML report is wrong as it would list to many testcases when you browse each junit test class.

It can be tested by checking out the source code from XWork and run: mvn test.
