找不到与IntelliJ中的Method main匹配的测试

Question

My class is a test class and it has the following structure:

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");
    }

}

If I press the right click on the main method > Run 'main', it throws the following exception:

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 com.intellij.rt.execution.application.AppMain.main(AppMain.java:140)

If I press right click on the class name > Run 'MyClassTest.main()' it works fine printing:

in main

If I comment out @RunWith(PowerMockRunner.class) , everything works fine in both cases.

The same problem appears if I use @RunWith(MockitoJUnitRunner.class) instead of @RunWith(PowerMockRunner.class) .

Why is that difference?

Details:

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

Answer 1

抛出异常是因为main方法上没有@Test批注。

Answer 2

Please check that you have a powermock required version of javassist library in your classpath.

Junit seems not able to report the correct root failure reason in this case. For the details,you can see this issue .
