@Test public void testLoadPath() { final Path path = mock(Path.class); final org.uberfire.java.nio.file.Path nioPath = mock(org.uberfire.java.nio.file.Path.class); final String expectedContent = "<dmn/>"; final byte[] contentBytes = expectedContent.getBytes(); doReturn(nioPath).when(helper).convertPath(path); when(ioService.newInputStream(nioPath)).thenReturn(new ByteArrayInputStream(contentBytes)); final Optional<InputStream> inputStream = helper.loadPath(path); assertTrue(inputStream.isPresent()); assertEquals(expectedContent, new Scanner(new InputStreamReader(inputStream.get())).next()); }
