PowerMockTestCase subclass test crashes #545

Open GoogleCodeExporter opened 8 years ago

GoogleCodeExporter commented 8 years ago
While writing a test with powermock 1.6.2 and TestNG 6.8.21 when a test of 
class that subclasses PowerMockTestCase there is a consistent crash.

Code under test:
package p;

public class Foo {
    public static void foo() throws Exception {
        throw new Exception("huh?");
    }
}

Test class:
package p;

import org.mockito.MockitoAnnotations;
import org.powermock.api.mockito.PowerMockito;
import org.powermock.core.classloader.annotations.PrepareForTest;
import org.powermock.modules.testng.PowerMockTestCase;
import org.testng.Assert;
import org.testng.annotations.BeforeMethod;
import org.testng.annotations.Test;
import p.Foo;

import static org.powermock.api.mockito.PowerMockito.mockStatic;

@PrepareForTest({p.Foo.class})
public class FooTest extends PowerMockTestCase {

    @BeforeMethod
    public void setup() {
        mockStatic(FooTest.class);
        MockitoAnnotations.initMocks(this);
    }

    @Test
    public void test() throws Exception {
        PowerMockito.doNothing().when(FooTest.class,"foo");
        p.Foo.foo();

        Assert.assertEquals(1, 1);
    }
}

The error:
org.testng.TestNGException:

from inside of a branch

PS, converting to JUnit solves the issue, but we prefer TestNG.
