But I am getting following error :

I have been mocking private methods for other classes, everything works fine.
The only difference between other classes and the class for which test case is failing is it has enum called :
private enum PortMetric {
READ_IOS, WRITE_IOS, KBYTES_READ, KBYTES_WRITTEN
}

Please add a small self contained code sample that demonstrates how to reproduce this - with only the enum and stack text it’s hard to help.

Sample code to reproduce the issue : class SampleCode { public void method1() { System.out.println(method2()) } private PortMetricEnum method2() { return PortMetricEnum.READ_IOS } enum PortMetricEnum { READ_IOS } }

Sample testcase : import org.junit.Test import org.junit.runner.RunWith import org.powermock.api.mockito.PowerMockito import org.powermock.core.classloader.annotations.PrepareForTest import org.powermock.modules.junit4.PowerMockRunner @RunWith(PowerMockRunner.class) @PrepareForTest(SampleCode.class) class TestSampleCode { @Test void testMethod1() { SampleCode obj = PowerMockito.spy(new SampleCode()) PowerMockito.doReturn("North").when(obj, "method2") System.out.println(obj.method1()) } }

I have been mocking private methods for other classes, everything works fine.
The only difference between other classes and the class for which test case is failing is it has enum called :
private enum PortMetric {
READ_IOS, WRITE_IOS, KBYTES_READ, KBYTES_WRITTEN
}
java enums powermock powermockito
java enums powermock powermockito

Please add a small self contained code sample that demonstrates how to reproduce this - with only the enum and stack text it’s hard to help.

The issue is because my enum was within a class and according to java specification enum within a class is by default static. Once I put the enum outside class, issue was resolved.
