### Question:
NonRecurrentActorCriticHelper extends ActorCriticHelper { @Override public INDArray createPolicyLabels(int trainingBatchSize) { return Nd4j.zeros(trainingBatchSize, actionSpaceSize); } NonRecurrentActorCriticHelper(int actionSpaceSize); @Override INDArray createValueLabels(int trainingBatchSize); @Override INDArray createPolicyLabels(int trainingBatchSize); @Override void setPolicy(INDArray policy, long idx, int action, double advantage);  }### Answer:
@Test public void when_callingCreatePolicyLabels_expect_ZeroINDArrayWithCorrectShape() { INDArray result = sut.createPolicyLabels(4); assertArrayEquals(new long[] { 4, 3 }, result.shape()); for(int j = 0; j < 4; ++j) { for(int i = 0; i < 3; ++i) { assertEquals(0.0, result.getDouble(j, i), 0.00001); } } }
