PowerMockito.whenNew Fail !

[jason0909]

The following is my test code ,but some exception information is throw ? can you tell me why/?

package com.example.mock;

import java.io.File;

import org.mockito.Mockito;

import org.powermock.api.mockito.PowerMockito;

import org.powermock.core.classloader.annotations.PrepareForTest;

import org.testng.Assert;

import org.testng.annotations.Test;

public class TestMockito {

@Test

   public void testRegisterService2() throws Exception {  

       String s="A:/aa.txt";  

       File file=PowerMockito.mock(File.class);  

       PowerMockito.whenNew(File.class).withArguments(Mockito.anyString()).thenReturn(file);  

       PowerMockito.when(file.exists()).thenReturn(true);  

       PowerMockito.verifyNew(File.class).withArguments(s);

       File a=new File(s);  

       System.out.println(a.exists());

       Assert.assertEquals(true, a.exists());  

   }  

}

the exception information:

FAILED: testRegisterService2

java.lang.AssertionError: Wanted but not invoked java.io.File(

    "A:/aa.txt"

);

Actually, there were zero interactions with this mock.

You're missing the RunWith and PrepareForTest annotation?

Have you added the PowerMockRunner to suite.xml? Otherwise extend from PowerMockTestCase.
