1You can use PowerMockito.mockStatic() to mock static methods. For example:2public class ClassUnderTest {3    public String someMethod() {4        return UUID.randomUUID().toString();5    }6}7public class ClassUnderTestTest {8    public void testSomeMethod() throws Exception {9        PowerMockito.mockStatic(UUID.class);10        PowerMockito.when(UUID.randomUUID()).thenReturn(new UUID(0, 0));11        assertEquals("00000000-0000-0000-0000-000000000000", new ClassUnderTest().someMethod());12    }13}
