What if the class we want to mock is in a different package? In this case, we have to use PowerMockito.mockStatic() method. In the following example we mock the static method of the java.lang.System class:9import org.junit.Test;10import org.powermock.api.mockito.PowerMockito;11import org.powermock.reflect.Whitebox;12import java.io.PrintStream;13import static org.assertj.core.api.Assertions.assertThat;14public class MainMockTransformerTestSupportTest {15 public void testMockStaticReturnMethod() {16 PowerMockito.mockStatic(System.class);17 PrintStream printStream = new PrintStream(System.out);18 PowerMockito.when(System.out).thenReturn(printStream);19 Whitebox.invokeMethod(System.out, "println", "Hello World!");20 assertThat(printStream.toString()).isEqualTo("Hello World!");21 }22}23In the previous example we used the Whitebox.invokeMethod() method to invoke the println() method. In the following example we use the PowerMockito.verifyStatic() method to verify that the println() method was called:24import org.junit.Test;25import org.powermock.api.mockito.PowerMockito;26import org.powermock.reflect.Whitebox;27import java.io.PrintStream;28import static org.assertj.core.api.Assertions.assertThat;29public class MainMockTransformerTestSupportTest {30 public void testMockStaticReturnMethod() {31 PowerMockito.mockStatic(System.class);32 PrintStream printStream = new PrintStream(System.out);33 PowerMockito.when(System.out).thenReturn(printStream);34 Whitebox.invokeMethod(System.out, "println", "Hello World!");35 PowerMockito.verifyStatic(System.class);36 Whitebox.invokeMethod(System.out, "println", "Hello World!");37 }38}39In the previous example we used the Whitebox.invokeMethod() method to invoke the println() method. In the following example we use the PowerMockito.verifyStatic() method
