1public void testPrivateMethod() {2 PartialMockingExample mock = PowerMockito.mock(PartialMockingExample.class);3 String result = Whitebox.invokeMethod(mock, "privateMethod");4 Assert.assertEquals("privateMethod", result);5}6Let’s take an example of a class named PartialMockingExample. This class contains a static method named staticMethod() which returns a string value “staticMethod”. The following code snippet shows the class:7public class PartialMockingExample {8 public static String staticMethod() {9 return "staticMethod";10 }11}12Now, let’s write a test case for testing the staticMethod() method of PartialMockingExample class. The following code snippet shows the test case:13public void testStaticMethod() {14 PartialMockingExample mock = PowerMockito.mock(PartialMockingExample.class);15 String result = Whitebox.invokeMethod(mock, "staticMethod");16 Assert.assertEquals("staticMethod", result);17}18Let’s take an example of a class named PartialMockingExample. This class contains a final method named finalMethod() which returns a string value “finalMethod”. The following code snippet shows the class:
