---------------------------------
Have you tested this on trunk? I am pretty sure that there are unit tests that
verify the correct behavior.
> Can't listen to file modifications, event raised is fileCreated rather than
> fileChanged
> ---------------------------------------------------------------------------------------
>
> Key: VFS-234
> URL: https://issues.apache.org/jira/browse/VFS-234
> Project: Commons VFS
> Issue Type: Bug
> Affects Versions: 1.0
> Environment: Windows, Java 6
> Reporter: Antonio Terreno
>
> It seems like that a FileCreated event is raised even when the file changes.
> I checked out the tests on the repository and the test is on file creation
> not modification.
> The below test uses mockito to mock the Listener, I had the same result using
> a real listener.
> @Test
> public void testShouldListenToFileChanges() throws Exception {
> FileObject child = folder.resolveFile( "fileToChange.txt" );
> FileSystem fs = folder.getFileSystem();
>
> FileMonitor defaultFileMonitor = new DefaultFileMonitor(fileListener);
> defaultFileMonitor.addFile( child );
> fs.addListener( child, fileListener );
> OutputStream out = child.getContent().getOutputStream();
> out.write( "bla".getBytes() );
> out.close();
> child.getContent().close();
>
> verify( fileListener).fileCreated( argThat( isAFileChangeEventOn(
> child ) ) );
> verify( fileListener).fileChanged( argThat( isAFileChangeEventOn(
> child ) ) );
> }
> class FileChangeEventMatcher extends BaseMatcher<FileChangeEvent> {
>
> private final FileObject fileObject;
> public FileChangeEventMatcher( FileObject fileObject ) {
> this.fileObject = fileObject;
> }
>
> public static FileChangeEventMatcher isAFileChangeEventOn( FileObject
> child ) {
> return new FileChangeEventMatcher( child );
> }
> @Override
> public boolean matches( Object obj ) {
> FileChangeEvent event = (FileChangeEvent) ( obj );
> if ( event.getFile().equals( fileObject ) )
> return true;
> return false;
> }
> @Override
> public void describeTo( Description description ) {
> }
> }
