TestNG和Powermockito-不能模拟静态void

Question

我无法使用TestNG获得Powermock工作。调整为JUnit的相同代码运行良好，但在TestNG中不知何故失败了。TestNG版本为6.8.21Powermockito版本为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?");
    }
}

我得到的例外是在when方法上：

java.lang.Exception: huh?

那么我在这里错过了什么？

我怀疑这可能是与此问题相同的问题和解决方案。换句话说，请确保您正在使用org.powermock.modules.testng.PowerMockObjectFactory。但正如@fge所说，您应该@PrepareForTest包含要模拟的静态方法的类，而不应该是测试类本身。。。
