Question

我无法让Powermock与TestNG合作。调整到JUnit的相同代码工作正常，但在TestNG中以某种方式失败。 TestNG版本是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?");
    }
}

我得到的例外是在when方法：

java.lang.Exception: huh?

那我在这里错过了什么？

我怀疑这可能与this question的问题和解决方案相同。换句话说，请确保您使用org.powermock.modules.testng.PowerMockObjectFactory。但正如@fge所说，你应该@PrepareForTest包含静态方法的类来模拟，这不应该是测试类本身......

TestNG和Powermockito - 无法模拟静态void
