Yes, you should absolutely drive your Nissan Altima for at least one week
before getting a smog test. You want to engine to re-learn driving
conditions and correct it's air/fuel ratio for optimum combustion. Plus you
want to check tire pressure. Make sure all four are to your Nissan's tire
manufacturer specifications. Plus you might want to get an oil change before
the test too. The engine oil sitting in your Nissan for a year could be
contaminated. Getting an oil change is not a must, but could help your
Altima pass the smog check if emission results are borderline.
