### Question:
NOP extends JVMInstruction { public NOP () { } NOP(); Conditional<Instruction> execute(FeatureExpr ctx, ThreadInfo th); int getByteCode();  }### Answer:
@Test public void testNOP() throws Exception { final One<Integer> first = One.valueOf(3); StackFrame stackFrame = createStackFrame(2, 0, getInstruction()); stackFrame.push(FeatureExprFactory.True(), first); executedCode(stackFrame); assertEquals(first, stackFrame.pop(FeatureExprFactory.True())); }
