Ive been trying to mock a final class(Paths)

@Test
public void testShouldCheckIfThereAreAnyChangesInTheFolder() throws Exception {
    Paths paths = PowerMockito.mock(Paths.class);
    Mockito.when(Paths.get("test/test/test")).thenReturn(path);

    fileSystem = path.getFileSystem();
    WatchService watchService = fileSystem.newWatchService();
    fileWatcher = new FileWatcher(path, fileSystem, watchService);

    fileWatcher.listenToFolderChanges();


}

But I keep getting this error

org.mockito.exceptions.misusing.MissingMethodInvocationException: when() requires an argument which has to be 'a method call on a mock'. For example: when(mock.getArticles()).thenReturn(articles);

I don't want to do a Paths.get() of the actual path because the test keeps on hanging because its listening to the actual class

Try PowerMockito.when() instead of Mockito.when() – Brandon McKenzie Jun 13 '16 at 13:01

Possibly duplicate of http://stackoverflow.com/questions/10583202/powermockito-mock-single-static-method-and-return-object as you are using static method. – sauumum Jun 13 '16 at 15:48
Thank you I managed to get it right. – Mathabo Matjiu Jun 14 '16 at 07:10
