java - TestNG and Powermockito - cannot mock static void -

i can't powermock work testng. same code adjusted junit works fine, somehow in testng fails. testng version 6.8.21 powermockito version 1.6.1

package p;  import org.mockito.mockitoannotations; import org.powermock.api.mockito.powermockito; import org.powermock.core.classloader.annotations.preparefortest; import org.powermock.modules.junit4.powermockrunner; import org.testng.assert; import org.testng.annotations.beforetest; import org.testng.annotations.test;   import static org.powermock.api.mockito.powermockito.mockstatic;  @preparefortest({footest.class}) public class footest {      @beforetest     public void setup() {         mockstatic(footest.class);         mockitoannotations.initmocks(this);     }      @test     public void test() throws exception {         powermockito.donothing().when(footest.class,"foo");         footest.foo();          assert.assertequals(1, 1);     }      public static void foo() throws exception {         throw new exception("huh?");     } } 

the exception on when method:

java.lang.exception: huh?     @ p.footest.foo(footest.java:32)     @ sun.reflect.nativemethodaccessorimpl.invoke0(native method)     @ sun.reflect.nativemethodaccessorimpl.invoke(nativemethodaccessorimpl.java:57)     @ sun.reflect.delegatingmethodaccessorimpl.invoke(delegatingmethodaccessorimpl.java:43)     @ java.lang.reflect.method.invoke(method.java:606)     @ org.powermock.reflect.internal.whiteboximpl.performmethodinvocation(whiteboximpl.java:1873)     @ org.powermock.reflect.internal.whiteboximpl.doinvokemethod(whiteboximpl.java:773)     @ org.powermock.reflect.internal.whiteboximpl.invokemethod(whiteboximpl.java:753)     @ org.powermock.reflect.whitebox.invokemethod(whitebox.java:466)     @ org.powermock.api.mockito.internal.expectation.powermockitostubberimpl.when(powermockitostubberimpl.java:106)     @ p.footest.test(footest.java:25)     @ sun.reflect.nativemethodaccessorimpl.invoke0(native method)     @ sun.reflect.nativemethodaccessorimpl.invoke(nativemethodaccessorimpl.java:57)     @ sun.reflect.delegatingmethodaccessorimpl.invoke(delegatingmethodaccessorimpl.java:43)     @ java.lang.reflect.method.invoke(method.java:606)     @ org.testng.internal.methodinvocationhelper.invokemethod(methodinvocationhelper.java:85)     @ org.testng.internal.invoker.invokemethod(invoker.java:696)     @ org.testng.internal.invoker.invoketestmethod(invoker.java:882)     @ org.testng.internal.invoker.invoketestmethods(invoker.java:1189)     @ org.testng.internal.testmethodworker.invoketestmethods(testmethodworker.java:124)     @ org.testng.internal.testmethodworker.run(testmethodworker.java:108)     @ org.testng.testrunner.privaterun(testrunner.java:767)     @ org.testng.testrunner.run(testrunner.java:617)     @ org.testng.suiterunner.runtest(suiterunner.java:348)     @ org.testng.suiterunner.runsequentially(suiterunner.java:343)     @ org.testng.suiterunner.privaterun(suiterunner.java:305)     @ org.testng.suiterunner.run(suiterunner.java:254)     @ org.testng.suiterunnerworker.runsuite(suiterunnerworker.java:52)     @ org.testng.suiterunnerworker.run(suiterunnerworker.java:86)     @ org.testng.testng.runsuitessequentially(testng.java:1224)     @ org.testng.testng.runsuiteslocally(testng.java:1149)     @ org.testng.testng.run(testng.java:1057)     @ org.testng.remote.remotetestng.run(remotetestng.java:111)     @ org.testng.remote.remotetestng.initandrun(remotetestng.java:204)     @ org.testng.remote.remotetestng.main(remotetestng.java:175)     @ org.testng.remotetestngstarter.main(remotetestngstarter.java:125)     @ sun.reflect.nativemethodaccessorimpl.invoke0(native method)     @ sun.reflect.nativemethodaccessorimpl.invoke(nativemethodaccessorimpl.java:57)     @ sun.reflect.delegatingmethodaccessorimpl.invoke(delegatingmethodaccessorimpl.java:43)     @ java.lang.reflect.method.invoke(method.java:606)     @ com.intellij.rt.execution.application.appmain.main(appmain.java:134)     @ sun.reflect.nativemethodaccessorimpl.invoke0(native method)     @ sun.reflect.nativemethodaccessorimpl.invoke(nativemethodaccessorimpl.java:57)     @ sun.reflect.delegatingmethodaccessorimpl.invoke(delegatingmethodaccessorimpl.java:43)     @ java.lang.reflect.method.invoke(method.java:606)     @ com.intellij.rt.execution.commandlinewrapper.main(commandlinewrapper.java:130) =============================================== custom suite total tests run: 1, failures: 1, skips: 0 =============================================== 

so missing here?

i suspect may same issue , solution this question. in other words make sure using org.powermock.modules.testng.powermockobjectfactory. @fge says, should @preparefortest class containing static method(s) mock, should not test class itself...
