### Question:
And extends InputFunction implements Serializable { public double getOutput(List<Connection> inputConnections) { if (inputConnections.size() == 0) return 0d; boolean output = true; for (Connection connection : inputConnections) { output = output && (connection.getInput() >= 0.5d); } return output ? 1d : 0d; }  double getOutput(List<Connection> inputConnections);  }### Answer:
@Test public void testGetOutput() { for (int i = 0; i < inputNeurons.size(); i++) { inputNeurons.get(i).setInput(inputs[i]); inputNeurons.get(i).calculate(); } double result = instance.getOutput(inputConnections); assertEquals(expected, result, 0.000001); }
