I'm trying to mock a static method of a final class : Files.exist by example.
I read that I have to user a mock-maker-inline mockito plugin so I set it up :
I put this :
mock-maker-inline
in : src/test/resources/mockito-extensions/org.mockito.plugins.MockMaker
and then I mocked my class and try to verify that my mock is called :
@PrepareForTest(Files.class)
@RunWith(PowerMockRunner.class)
public class StaticFinalMethodTests
{
@InjectMocks
private FileManipulationClass fileManipulationClass;
@Before
public void setUp()
{
PowerMockito.mockStatic(Files.class);
}
@Test
public void fileManipulationTest() throws IOException
{
Mockito.when(Files.exists(Mockito.nullable(Path.class))).thenReturn(false);
Files.exists(getDummyPath());
PowerMockito.verifyStatic(Files.class);
Files.exists(getDummyPath());
}
private Path getDummyPath()
{
return Paths.get("/dummy/path");
}
}
And I have this exception :
