TestNG和Powermockito - 無法模擬靜態無效

我無法使用TestNG獲取Powermock。調整爲JUnit的代碼工作正常，但在TestNG中以某種方式失敗。 TestNG的版本是21年6月8日 Powermockito版本是1.6.1TestNG和Powermockito - 無法模擬靜態無效

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?"); 
    } 
}

我得到的例外是在當方法：

那我在這裏失蹤？

好的，除了你不應該在靜態方法中嘲笑第一，我不確定你可以'@ PrepareForTest'你的測試類本身;你有沒有嘗試過，並將該方法放在另一個班級？ – fge 2015-04-01 14:44:23

@fge出於好奇，當需要出現時，嘲弄靜態方法有什麼不對？在一個真實世界的應用程序中，我最近不得不嘲笑其中的一些（在JSF'FacesContext'類中，以及JasperReports的一個類中）;如果我不嘲笑他們，我還會寫測試嗎？爲'FacesContext'和JasperReports創建不必要的包裝器？ – 2015-04-01 21:50:03

@fge，當然了。這只是一個最小化的樣本。順便說一句，當我轉換爲JUnit時，它工作正常。 – 2015-04-07 11:22:00

我懷疑這可能是與this question相同的問題和解決方案。換句話說，確保你使用的是org.powermock.modules.testng.PowerMockObjectFactory。但正如@fge所說，你應該包含靜態方法來模擬這個類，它不應該是測試類本身......
