For example:18package samples.fieldmock;19import org.junit.Assert;20import org.junit.Test;21import org.powermock.api.easymock.PowerMock;22import org.powermock.core.classloader.annotations.PrepareForTest;23@PrepareForTest(FieldInitializerDemo.class)24public class FieldInitializerDemoTest {25    public void testFieldInitializerDemo() throws Exception {26        PowerMock.mockStatic(FieldInitializerDemo.class);27        PowerMock.expectPrivate(FieldInitializerDemo.class, "getTestField").andReturn("test");28        PowerMock.replayAll();29        final String testField = FieldInitializerDemo.getTestField();30        PowerMock.verifyAll();31        Assert.assertEquals("test", testField);32    }33}34PowerMock supports mocking final fields. You can mock final fields by using PowerMock.mockFinal() method. For example:35package samples.fieldmock;36import org.junit.Assert;37import org.junit.Test;38import org.powermock.api.easymock.PowerMock;39import org.powermock.core.classloader.annotations.PrepareForTest;40@PrepareForTest(FieldInitializerDemo.class)41public class FieldInitializerDemoTest {
