Try to put initMocks in @Before instead of @BeforeClass method. What you are trying to do is to set some fields in a static method. That's my guess.
Initializing Exception error when using Mockito with PowerMock
Pregunta
I'm using Mockito with PowerMock for the first time and I'm having an error when running the below code at the following line:
MockitoAnnotations.initMocks(SearchTest.class);
The error is:
java.lang.ExceptionInInitializerError

The code for the test class is:

this.expectedPreFile= folder + "/inpRowsExpected.json";
this.postFile= folder + "/outRows.json";
this.expectedpostFile= folder + "/outRowsExpected.json";
}
@Test
/**

*/
public void testHandler() throws Exception {
/**********Set the expected results for the mocked methods****************/
Mockito.when(mockHttpClient.execute(mockHttpPost)).thenReturn(mockHttpResponse);
Mockito.when(mockHttpResponse.getEntity()).thenReturn(mockHttpEntity);
Mockito.when(mockHttpEntity.getContent()).thenReturn(mockInputStream);
PowerMockito.whenNew(InputStreamReader.class).withArguments(mockInputStream).thenReturn(mockInputStreamReader);
PowerMockito.whenNew(BufferedReader.class).withArguments(mockInputStreamReader).thenReturn(mockBufferedReader);
PowerMockito.whenNew(JSONObject.class).withArguments(Matchers.any(String.class)).thenReturn(jsonStub);
searchHandler.pre(); //Call the actual Pre method to be tested
}
}
Any suggestions why I'm getting this error?
Thanks
