【问题描述】：
我无法让 Powermock 与 TestNG 一起工作。调整为 JUnit 的相同代码工作正常，但在 TestNG 中它以某种方式失败。 TestNG 版本为 6.8.21 Powermockito 版本是 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 when 方法：
java.lang.Exception: huh?

那么我在这里错过了什么？
【问题讨论】：

好的，除了你不应该首先模拟静态方法之外，我不确定你是否可以
@PrepareForTest你的测试类本身；您是否尝试过将该方法放在另一个类中？ -
@fge 出于好奇，在需要时模拟静态方法有什么问题？在一个真实世界的应用程序中，我最近不得不模拟其中的一些（在 JSF
FacesContext类和 JasperReports 的类中）；如果我不嘲笑他们，我还能如何编写测试？为FacesContext和 JasperReports 创建不必要的包装器？ -
@fge，我确实做到了。这只是一个最小化的样本。顺便说一句，当我转换为 JUnit 时，它工作正常。
