### Question:
Sphinx extends SphinxBaseRecognizer { @Override protected RecognitionResult startImpl() throws SpeechException { fireRecognizerEvent(RecognizerEvent.RECOGNIZER_LOADING); assert context != null : "cannot start recognition without a context"; csr = context.getRecognizer(); context.getVadListener().setRecognizer(this); vadInSpeech = false; SpeechResult speechResult; boolean isMatch; stopping = false; csr.startRecognition(); do { fireRecognizerEvent(RecognizerEvent.RECOGNIZER_READY); speechResult = csr.getResult(); if (speechResult == null) break; isMatch = isMatch(speechResult); if (!isMatch) fireRecognizerEvent(new RecognizerEvent(this, RecognizerEvent.INVALID_RESULT, sphinx2DOSResult(speechResult))); } while (!isMatch && !stopping && isActive()); csr.stopRecognition(); if (speechResult != null && !stopping) { RecognitionResult sphinxResult = sphinx2DOSResult(speechResult); fireRecognizerEvent(sphinxResult); return sphinxResult; } else { return null; } } Sphinx(); SphinxLanguageSettings getLanguageSettings(Language l); @Override Language[] getLanguages(); @Override void setContext(RecognitionContext context); @Override RecognitionContext getContext(); @Override SphinxContext createTemporaryContext(Grammar g, Domain domain);  }### Answer:
@Test(expected = NullPointerException.class, timeout=10000) public void invalidRecognitionSetupTest() throws SpeechException { Sphinx sphinx = new Sphinx(); try { sphinx.startImpl(); } catch (AssertionError | NullPointerException e) { throw new NullPointerException(); } }
