我试图对我的套接字服务器代码进行单元测试。我使用Mockito但是当SUT运行到下一行时会爆炸，因为这是最后一种方法。
socketChannel.register()
我是PowerMock的新手，我正在尝试使用它，但无论我尝试什么，我都面临各种问题。如果有人可以帮助审核以下内容并提供一些非常好的帮助。
以下是用于测试的代码。
import org.apache.logging.log4j.LogManager;
import org.apache.logging.log4j.Logger;
import org.mockito.Mockito;
import org.powermock.api.mockito.PowerMockito;
import org.powermock.core.classloader.annotations.PrepareForTest;

@ActiveProfiles("QuickTest")
@Component
@ContextConfiguration(classes = AppConfigQuickTest.class)
@PrepareForTest({SocketChannel.class, QuickTest.class})
public class QuickTest extends AbstractTestNGSpringContextTests {
// An error occurred while instantiating class com.QuickTest: Could not initialize class org.apache.logging.log4j.util.PropertiesUtil
// Caused by: java.lang.NoClassDefFoundError: Could not initialize class org.apache.logging.log4j.util.PropertiesUtil

private static final Logger logger = LogManager.getLogger("QuickTest");
@ObjectFactory
public IObjectFactory getObjectFactory() {
return new org.powermock.modules.testng.PowerMockObjectFactory();
}
@Test
public void socketTest() throws IOException {
int bytesWritten = 5;
SocketChannel socketChannel = PowerMockito.mock(SocketChannel.class);
SocketAddress socketAddress = new InetSocketAddress("abc.com", 12340);
Mockito.when(socketChannel.getRemoteAddress()).thenReturn(socketAddress);
Mockito.when(socketChannel.write((ByteBuffer) Mockito.any())).thenReturn(bytesWritten);
// todo: socketChannel.register() is causing Mockito to throw null pointer exception because it's a final method
Mockito.doNothing().when(socketChannel.register(Mockito.any(), Mockito.any()));
// further stuff down here to setup and do test
}
}
第一个问题
以下一行出现问题。
private static final Logger logger = LogManager.getLogger("QuickTest");
这是完整的堆栈跟踪。

第三个问题
如果我删除了＆＃39; extends AbstractTestNGSpringContextTests＆＃39;在课堂上我仍然得到以下内容。在这一点上，我不确定我还能尝试什么。
