Using AI Code Generation

1I have a question related to mocking static methods. I have a class which is using a static method from another class. I am trying to mock the static method from the other class using PowerMock. I am able to mock the static method using PowerMockito.mockStatic() but the method is not getting mocked. I am using PowerMockito 1.6.2 version. Here is my code:2public class TestClass {3    public void testMethod() {4        System.out.println(OtherClass.getValue());5    }6}7public class OtherClass {8    public static String getValue() {9        return "test";10    }11}12@RunWith(PowerMockRunner.class)13@PrepareForTest(OtherClass.class)14public class PowerMockTest {15    public void testMethod() throws Exception {16        PowerMockito.mockStatic(OtherClass.class);17        PowerMockito.when(OtherClass.getValue()).thenReturn("test2");18        TestClass testClass = new TestClass();19        testClass.testMethod();20    }21}22public class TestClass {23    public void testMethod() {24        System.out.println(OtherClass.getValue());25    }26}27public class OtherClass {28    public static String getValue() {29        return "test";30    }31}32@RunWith(PowerMockRunner.class)33@PrepareForTest(OtherClass.class)34public class PowerMockTest {35    public void testMethod() throws Exception {36        PowerMockito.mockStatic(OtherClass.class);37        PowerMockito.when(OtherClass.getValue()).thenReturn("test2");38        TestClass testClass = new TestClass();39        testClass.testMethod();40    }41}
