在eclipse中運行junit testcase時出錯

我正在使用Junit 4，並且我正在使用2個庫來處理junit中的嘲諷。以下是我的代碼。在eclipse中運行junit testcase時出錯

package tutorials; 

import static org.mockito.Mockito.when; 

import org.junit.Assert; 
import org.junit.Test; 
import org.junit.runner.RunWith; 
import org.mockito.InjectMocks; 
import org.mockito.Mock; 
import org.mockito.runners.MockitoJUnitRunner; 

// @RunWith attaches a runner with the test class to initialize the test data 
@RunWith(MockitoJUnitRunner.class) 
public class MathApplicationTester { 

    //@InjectMocks annotation is used to create and inject the mock object 
    @InjectMocks 
    MathApplication mathApplication = new MathApplication(); 

    //@Mock annotation is used to create the mock object to be injected 
    @Mock 
    CalculatorService calcService; 

    @Test 
    public void testAdd(){ 
     //add the behavior of calc service to add two numbers 
     when(calcService.add(10.0,20.0)).thenReturn(30.00); 

     //test the add functionality 
     Assert.assertEquals(mathApplication.add(10.0, 20.0),30.0,0); 
    } 
}

運行上述方法JUnit測試。繼錯誤信息後進行顯示。

我使用的Mockito - 全1.10.19.jar和powermock模塊，junit4-1.6.6.jar.Can誰能幫我解決這個問題。
