This agent will be used to suppress the constructor of the SuppressConstructorHierarchyDemo class. So, when we create a new instance of this class, the constructor will not be called. Thus, the call to assertEquals() will fail with an NPE:14    at samples.powermockito.junit4.agent.SuppressConstructorHierarchyDemo.sayHello(SuppressConstructorHierarchyDemo.java:8)15    at samples.powermockito.junit4.agent.SuppressConstructorHierarchyDemoTest.testNotSuppressConstructorWithoutByteCodeManipulation(SuppressConstructorHierarchyDemoTest.java:25)16To fix this, we can use PowerMockito.suppress() to suppress the constructor. The following test will pass:17import org.junit.runner.RunWith;18import org.powermock.core.classloader.annotations.PrepareForTest;19import org.powermock.modules.junit4.PowerMockRunner;20import org.powermock.modules.junit4.agent.PowerMockAgent;21@RunWith(PowerMockRunner.class)22@PrepareForTest(SuppressConstructorHierarchyDemo.class)23public class SuppressConstructorHierarchyDemoTest {24    public void testSuppressConstructor() throws Exception {25        PowerMockito.suppress(PowerMockito.constructor(SuppressConstructorHierarchyDemo.class));26        final SuppressConstructorHierarchyDemo demo = new SuppressConstructorHierarchyDemo();27        assertEquals("Hello World!", demo.sayHello());28    }29}30The PowerMockito.suppress() method can be used to suppress any method, constructor or field. This is useful when you need to test a method that has a dependency on another class
