没有测试发现在IntelliJ中匹配Method main

Question

我的类是一个测试类,它具有以下结构:

import org.junit.Test;
import org.junit.runner.RunWith;
import org.powermock.modules.junit4.PowerMockRunner;

@RunWith(PowerMockRunner.class)
public class MyClassTest {

    public static void main(String[] args) {
        System.out.println("in main");
    }

    @Test
    public void maxTest() {
        System.out.println("test");
    }

}

如果我按下右键单击main方法>运行'main',它会抛出以下异常:

java.lang.Exception: No tests found matching Method main(MyClassTest) from org.junit.internal.requests.ClassRequest@26aa12dd
    at org.junit.internal.requests.FilterRequest.getRunner(FilterRequest.java:35)

    at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:62)
    at com.intellij.rt.execution.application.AppMain.main(AppMain.java:140)

如果我按下类名> Run'MyClassTest.main()',它可以正常打印:

in main

如果我发表评论@RunWith(PowerMockRunner.class),在这两种情况下一切正常.

如果我使用@RunWith(MockitoJUnitRunner.class)而不是,则会出现同样的问题@RunWith(PowerMockRunner.class).

为什么会有这种差异？

细节:

• Windows 7的
• JUnit 4.12
• PowerMock 1.6.2
• Java 8
• Maven 3
• IntelliJ IDEA 14.1.3

Answer 1

抛出异常,因为该main方法没有@Test注释.
